    obviously a car locked in a garage with its own seperate garage alarm system, with motion and door sensors adds a great deal of security , especially if its located inside a fenced yard with dogs, or in a yard where the house is almost always occupied, but just as obviously your not always home and your not always parking the car at home.
    steering wheel locks, kill switches, hidden fuel pump switches and wheel locks preventing the car from being easily driven or towed add a significant level of enhanced security, as do tracking systems like LO-JACK, and alarm systems that can,t be disabled by simply disconnecting the battery , or alarms that call your cell phone ,so you'll want to think thru whats correct for your application
    Asa general idea a multi layered redundant approach will provide he best results and simple tricks that slow or disable the car like like switches, hidden fuel pump switches and just making getting access to the car both more difficult and time consuming or very noticeable and well lighted when you park the car tend to make it a bit less likely to be a target.

    given time most alarms can be bypassed , but most thieves won,t want to get into a direct confrontation with the cars owner or try to trouble shoot a car that has an engine that dies constantly or one that's not easily rolled around or towed

    Tips to Prevent Car Theft

    * Take Your Keys. Nearly 20 percent of all vehicles stolen have the keys in them.
    * Lock Your Car. Approximately 50 percent of all vehicles stolen were left unlocked.
    * Never Hide a Second Set of Keys in Your Car. Extra keys can be easily found if a thief takes time to look.
    * Park in Well-lighted Areas. Over half of all vehicle thefts occur at night.
    * Park in Attended Lots. Auto thieves do not like witnesses and prefer unattended parking lots.
    * If You Park in an Attended Lot, Leave Only the Ignition/Door Key. If your trunk and glove box use the same key as the door, have one of them changed. Don't give the attendant easy access to your glove box and trunk. Upon returning, check the tires, spare tire, and battery to be sure they are the same as those you had when you parked.
    * Never Leave Your Car Running, Even if You'll Only be Gone For a Minute. Vehicles are commonly stolen at convenience stores, gas stations, ATMs, etc. Many vehicles are also stolen on cold mornings when the owner leaves the vehicle running to warm up.
    * Completely Close Car Windows When Parking. Don't make it any easier for the thief to enter your vehicle.
    * Don't Leave Valuables in Plain View. Don't make your car a more desirable target and attract thieves by leaving valuables in plain sight.
    * Park With Your Wheels Turned Toward the Curb. Make your car tough to tow away. Wheels should also be turned to the side in driveways and parking lots.
    * If Your Vehicle is Rear-Wheel Drive, Back into Your Driveway. Rear wheels
    lock on four-wheel drive vehicles, making them difficult to tow. Front-wheel drive vehicles should be parked front end first.
    * Always Use Your Emergency Brake When Parking. In addition to ensuring safety, using the emergency brake makes your car harder to tow.
    * If You Have a Garage, Use It. If you have a garage, take the time to use it rather than parking outside where your vehicle is more vulnerable.
    * When parking in a Garage, Lock the Garage Door and Your Vehicle. By locking both the garage and vehicle doors, the chances of deterring a thief greatly improve.
    * Don't leave the registration or Title in Your Car. A car thief will use these to sell your stolen car. File the title at your home or office, and carry registration in your purse or wallet.
    * Disable Your Vehicle When Leaving it Unattended for an Extended Period. Remove the electronic ignition fuse, coil wire, rotor distributor, or otherwise disable your vehicle anytime thieves may have extended access to it.
    * Replace T-Shaped Door Locks With Straight Locks. Some vehicle doors have lock assemblies at window level that flare out in a knob or "T" shape. A thief can use various tools to gain access inside the vehicle, grab and pull the lock. Straight locks prevent this.
    * Vehicle Identification Number (VIN). Stolen cars/parts are more easily traced when vehicle VIN numbers have been etched on car windows and major parts.
    * Engrave Expensive Accessories. Engrave personal ID numbers on car stereos, cellular phones, etc., so the thief will have difficulty disposing of them.

    Investing in Vehicle Protection

    * Ignition Kill Switch. Splice an inexpensive toggle switch into your ignition wire. The trick is hiding the switch well. Keypads, pressure pads and more expensive "immobilizers" and "passkeys" can also be used.
    * Fuel Kill Switch. The valve that halts the fuel supply is closed. Visible Steering Wheel Lock. Prevents the steering wheel from being turned.
    * Floorboard Locks. Devices that disable the gas or break pedal.
    * Gearshift Locks. Disables shifting of the transmission.
    * Tire/Wheel Locks. Prevents the vehicle from moving.
    * Hood Locks. Prevents the thief from gaining access to your security system and battery.
    * Armored Collar Around Steering Column. Protects the column and ignition.
    * Electronic Security Systems. Audio alarms sound loud warnings when doors/hood/trunk are opened. Optional sensors include glass breakage, motion, tampering and towing. Panic buttons and automatic engine disable features are also recommended.
    * Vehicle Tracking This is done with a transmitter hidden in the car that allows police to track the vehicle.

    Top 10 Ways to Steal a Car (and how to defend against them)
    By Caroline Pardilla, Production Editor

    Lists come out every year detailing the most stolen cars and, with that, what steps one can take to deter car thieves. Yet, a car is stolen in the United States every 24 seconds according to the Insurance Information Institute. Auto theft continues to thrive despite those lists and regardless of new anti-theft technology that emerges with every new model year.

    What else can you do besides not drive the most stolen car in America and equip your car with anti-theft protection? We're going to give you the unique opportunity to look inside the mind of the car thief and learn how he steals cars. With the help of police auto theft experts and auto theft professionals, we've compiled this list of some of the ways thieves steal cars followed by suggestions of how to stop them from doing it to you.

    We have no intention of providing new information to the wrong people and simply want to educate the good guys. We haven't disclosed anything that car thieves don't already know and we have left out specific details to avoid making this a "how-to." Knowing the insider tricks of auto thieves will motivate you to take the necessary precautions to defend your vehicle.

    1. Bump against the car to check for a car alarm. Since it seems like everything from a loud Harley to a rumbling garbage truck can set off a car alarm, people have been conditioned to tune them out. Instead of a motion-sensitive car alarm, use one that has a pager that will notify you as soon as your alarm is activated.

    2. Break the window or jimmy the lock to gain entry into a locked car. Don't tempt car thieves. Keep valuables out of plain sight. Take them with you or store them in the trunk. Also, if you have a stereo with a removable face plate, take it with you instead of tucking it away in the glovebox.

    3. Cut the steering wheel itself if there's a steering wheel lock. Instead of locking just your steering wheel, "lock" your car's ability to go by using a starter disable switch and putting it in a place where only you can get to it.

    4. Look for exposed wiring that can be cut or for the central unit of the car alarm to deactivate it. Instead of going to a big retail chain store, have your car alarm installed by a professional car alarm installer, preferably a reasonably shady one. Unlike retail chain employees, these experts know what it takes to make your car elusive to crooks.

    5. Look for car alarm decals to figure out which method to use to eliminate the alarm. Never display stickers that advertise what sort of car alarm you have, or audio system for that matter. Consider using a hood lock cable so the thief can't get to your battery or car alarm mechanism.

    6. Jump into an unattended running car while the owner is at the ATM, dropping off videos, etc. Never leave your keys in the ignition even for a quick errand. Car theft is a crime of opportunity, so don't make it easy for them to grab yours.

    7. Look for the car's title, registration or anything with a home address on it. Keep your registration and insurance information with you and never leave personal information in your car.

    8. Stake out sporting events, movie theaters and shopping center parking lots for the car of your choice since they offer the largest variety of cars in one area. Whenever possible, park in lots and garages that have security and/or parking lot attendants. If not, don't park in the farthest corner of the lot but rather near the entrance of these facilities to insure the most foot traffic (and the most potential witnesses). Also, opt for paying the extra couple of dollars for the monitored parking lot instead of using the free parking on the less-trafficked side streets.

    9. Find the second set of keys the owner "hid" in the car. Don't leave spare keys in your car or in a magnetic box attached to the underside of your car. Thieves know where all the "hiding places" are.

    10. Copy specific vehicle information and take it to the manufacturer to get a replacement key made. Instead of VIN etching the major parts of your vehicle, which doesn't turn most thieves off, drop your business card into the doors through the window slots to identify your car as yours.

    Even though auto theft is a crime of opportunity, if a crook really wants your car, he'll do whatever it takes to get it regardless of steering wheel locks or car alarms. But with the above knowledge, you can slow him down, make your car inconvenient to him and, hopefully, discourage him from attempting to steal your vehicle. Layering your car with anti-theft protection, especially if it's at the top of the most stolen vehicles list, is a good start. But, as with anything that is of value to you, the most important protection you can give your car is to take a proactive approach to security when you leave it unattended. ... affiliates

    a multi- layered approach to car security is the best route, simply things like, remembering to lock your car, and turn on an alarm helps, a hidden fuel pump cut off switch, key accessed ignition cutoff switch, and a steering wheel lock go a good way to prevent theft,systems like lo-jack to track it if it is stolen are a huge asset. simple steps like replacing the coil to distributor wire with a dummy replacement with the conductor removed, can cause a thief to abandon stealing the car.
    investing in a decent set of locks if you store the car helps
    parking in a locked garage with its own alarm obviously helps, and good lighting sure helps

    Re: security, parking your car with a bit more theft resista

    theres several ways to approach the problem and a hundred ways to make it more difficult for someone to drive your car away while your not in it!
    obviously simply steps like parking your car out in the parking lot where you can see it from inside the restaurant or store youll be going into helps keep you aware of whats going on, but you can,t always be looking so it helps to have both a decent quality alarm system and a separate delay device to delay or reduce the chances someone can successfully drive your car without your consent.
    obviously a kill switch MUST be difficult to easily access accidentally or recognize, as a kill switch to be consistently effective, yet be something you can activate without everyone noticing you doing it or the secrets out and useless in no time. hidden magnetic switches or relays that require a simple but precise sequence of events are a big help, so be creative.
    one guy I know had a custom ignition cut off with several small powerful magnets installed in his custom belt and micro magnetic switches inside the drivers seat lower back area, if he was not siting in the seat with his belt against the seat the car would not start.
    and (yes you might guess he got dressed to go to a wedding with a different belt and spent 20 minutes trying to figure out why his car would not start one day)

    an ignition cut off switch ... heft2.html

    a fuel cut off valve, is a good option

    a quick detach steering wheel is a second option,that makes stealing a car more difficult and theres several styles and methods of quickly detaching steering wheels

    Re: security, parking your car with a bit more theft resista

    One of my friends dropped by to show me a new security system idea he had thought up and fabricated /installed for his car, I think its absolutely brilliant, hes an electrical engineer by trade and a bit younger that I am and hes working on patenting the idea already but what it basically is, is hes combined a time delay sensor relay that completes a circuit with a
    magnetic proximity switch, and card scanner, the cars driver inserts a coded chip in his belt,wallet, shoes or what ever you choose that activates the relay,, the sensors about the size of a quarter ,so you could sew or glue or epoxy it into or onto, your belt, wallet, shoes,watch, fanny pack, jacket seam, or what ever, you can dream up, you could have several so the wife could have one so, when you enter the car, if the circuits active the car starts and runs normally, but if its not triggered, the cars ignition is effectively bye-passed. it works similar to the security chips that activate the door alarms like at home depot, where if they don,t scan your package at the cashier the door sensors sound an alarm if you try to exit the store carrying merchandise.
    if you have one of those key button deals that allow you to start a car remotely you have something similar and know how the cars alarm beeps as you get in and out of the car, but this is slightly different, in that its a second sensor, that the key alone won,t disable that works in tandem.
    the sensor knows your within 6-8 feet and the cars drivers compartment and activates the ignition, you still need a key to start and drive the car, but the key alone won,t allow the car to continue driving for more than 3-4 minutes unless it senses the hidden coded chip, in the area, if it does the car starts normally, its got a time delay so the ignition still works if you get out of the car for about 3-4 minutes everything still works, in fact just standing near the cars all thats required to allow the engine to run, but after it senses the chips not in the area, it opens the circuit and stops the car if it fails to sense you in proximity to the car, the idea being that if your car jacked the thief can take your keys and drive off but won,t get all that far before the car stops running.
    you can leave the key in the ignition and walk around the car, check the ignition timing etc. everything works, but walk more than about 15 feet away for more than 4 minutes and the car won,t run, because the sensor disables the circuit relay.
    obviously you would NOT want the security chip in your wallet or purse or on your car ignition key chain as any thief or car jacker might demand those at gun point, effectively making the process useless if he unknowingly has the chip, but it unlikely a car jacker would demand your belt, shoes or hat, if thats where you had the chip, and having a GPS LO-JACK,tracker and alarm in the car is also a great help, as is and fuel pump kill switch or steering wheel locks etc.

    The only obvious problem I see is us older guys forgetting about the layer of security and swapping belts, hats, shoes to new ones without the required chip, etc and spending a hour trying to start the car, due to failing to remember its required and winding up paying a towing charge to get the car "FIXED"

    Re: security, parking your car with a bit more theft resista

    you can also obviously place a HIDDEN, MANUAL fuel line cut off valve, in your cars fuel line at some point, that you can use to make starting the car much more difficult and time consuming for a potential thief

    Re: security, parking your car with a bit more theft resista

    I just read this yesterday, can't beat the price.

    DIY classic car immobiliser
    Under $10 for a remote-controlled immobiliser!
    By Julian Edgar

    At a glance...

    Perfect for an older or classic car
    Automatically arms when you leave the car
    Very cheap and easy to wire into place
    Fully built - no soldering required!

    Over the last 30-odd years the level of security built into cars has skyrocketed. Without having the right key, or a lot of time and electronic ability, thieves find stealing modern cars difficult. But that’s sure not the case for older cars. So what if you have an older car – an outright classic or simply an car you like driving for fun – that you want to make less stealable? And especially less stealable to an opportunistic thief?

    Well, for less than AUD$10 and 30 minutes of your time, you can now add a remote control immobiliser to your older car.

    The system

    Available on eBay for just AUD$5 plus postage is this electronic remote control switch - including postage to my Australian address, the total was about $9! It’s perfect for use as a remote control immobiliser.

    The key remote has a single pushbutton on it, while the associated box contains the receiver and a relay output. ... &_from=R40

    At the time of writing, the module plus remote was being sold on eBay by ‘windeal’ and the vendor called it the “12V Multi-function Learning Remote Control Switch New”. You can also find very similar devices available from other eBay sellers.

    As with a lot of items sold cheaply on eBay, the instructions are less than comprehensive. But that’s OK – here how it works out.

    Inside the receiver box you’ll find a small circuit board with a few LEDs, a configurable link and a 5-terminal strip.

    The functions of the important bits are as shown here.

    By changing the config link position you can set the device in the following ways. (Note that this is with the board orientated as shown in this diagram and viewed from above.)

    · No link – relay closes and green LED turns on only when remote button is being constantly pressed

    · Link set to left - relay closes and green LED turns on when remote button is pushed once, then stays on until power to the receiver is removed

    · Link set to right – relay closes and green LED turns on when remote button is pushed once, stays on until button is pushed again

    Having these different configs available makes the unit very useful.


    To disable the car, you’ll need first to decide on a wire that, if broken, will stop the car starting. A further caveat is that unless you add another relay, that wire should pass less than 10 amps when the car is running. (The remote receiver’s relay is rated at 10 amps.)

    The wire you choose to intercept could be to an electric fuel pump or the ignition coil.

    In the case of my 1979 Mercedes, I chose to disable the ignition coil. Furthermore, I mounted the receiver module under the bonnet and powered it from the wire I was disabling – an approach that made the wiring very simple.

    Here are the steps:

    1. Set the config link as shown – this means the relay will pull-in when the remote button is pressed and will stay latched until power to the unit is removed.

    2. Find the 12V feed to the coil. Note that if the car uses a ballast resistor, you will need to work ahead of the resistor as shown here.

    3. When the relay closes, the ‘common’ and ‘normally open’ connections are joined, so as shown here, when the relay is closed, power gets fed to the ballast resistor (and so then to the coil).

    4. Power for the module is gained from the ignition-switched 12V source feeding the ballast.

    5. You need to add a new ground wire for the module – connect this to the chassis.

    Wired in this way, the steps in starting the car as follows:

    1) Turn ignition key until dash warning lights are lit

    2) Press remote button

    3) Turn key further to start engine

    Note that pressing the remote with the car switched off doesn’t do anything – rather deceptive for a thief! Note also that you don’t need to press the remote button to activate the immobiliser when you leave the car – as soon as you turn the ignition off, the relay automatically opens.

    Here are the coil (black arrow) and ballast resistor (yellow arrow) in the Mercedes.

    The power supply lead to the ballast resistor was parted at the terminal and extensions put in place to connect to the immobiliser module.

    A ground connection for the immobiliser module was made at a convenient screw (and later I moved this to an even more convenient screw!).

    The fitted system, with the receiver module arrowed. Seal the module’s box with some neutral-cure silicone.

    If you wished to, you could disguise the writing by concealing it within the loom, so making it harder for a thief to find. You could also place the immobiliser module inside the cabin – the system has many tens of metres of radio range, so that won’t be a problem.


    A DIY, remote control immobiliser doesn’t get much cheap or easier than this!

    People can steal anything Grumpy .

    Best thing do if you have a classic valuable Musclecars like me is never let it see the light of day to no one.
    Work in secrecy.
    Only pull it out at night when most are asleep.

    Like the fuel shutoff valve.
    Waterman be best.,66617.html

    Battery disconnect switch hid in the trunk be great.

    Take the driveshaft out.
    No matter what they can not driveoff.

    theres a myriad of route's anyone can take to reduce the chances of having a prized muscle car stolen,
    while its true that a skilled determined thief can steal any car, its just not worth the risk involved,
    nothing is fool proof, given enough time anything can be stolen,
    BUT! you can make your cars theft far less attractive by
    greatly increasing the difficulty time and effort required, and risk.

    if you place an obviously multi layer defensive or protective barrier in place,
    the hidden ignition cut off, switches , fuel cut-off valves,motion sensor lighting and alarms,
    a locked garage, in a fenced in yard with an alarm system, a couple dogs, is a good start,
    video surveillance, lo-jack on the car itself, parking the car where its difficult to roll out,
    due to other cars in the way, removable steering wheels,

    a bit of ingenuity,video surveillance, a few relays and electrical contacts, motion sensor lights a cheap battery and trickle charger , and a couple 120db sirens could really help improve any security in a shop.

    Theives have got balls nowadays too! I was using my pressure washer other day, had taken my leather jacket off and laid it on Nova hood, walked inside to pull power cord, walked back out to wind it up! Some black motherfucker had it in his hand, man I was pissed! I reached inside and grabbed my lil helper(S &W 380 semi-auto), pointed it at his face! I said, “ Go ahead, take it motherfucker, but I hope you have enough blood to make it home! Cuz this clip has 7 shells in it! I believe you’ll need a transfusion before you get there!” Haha! He dropped it and ran, prolly pissing all over hisself! I love my lil buddy I keep on that 2X4 ! Best security in the world! I bet I don’t have anymore trouble! He’ll prolly tell his thief buddies, that motherfucker will fuck you up !!!!! Haha!

    Nice Bob.

    Just remember if your in Chicago or Burbs there same likely to occur.
    But if you give a warning they will pull out their Gun & Open Fire on You.
    So Just shoot instant.
    Don't have to kill its optional.

    They all have Guns & will open fire on You if you give a warning.

    here in fla,
    you can,t legally fire on,a criminal who runs
    ,with or without your property,
    "property theft alone, is at risk"
    you can be justified if the criminal
    "threatens you, in a manor that any reasonable person would view as an immediate and realistic threat to life or serious bodily harm"
    that will generally require they have a viable recognized, potential weapon,
    (gun,knife,lug wrench etc)
    and are facing or advancing on you,
    in response too you trying to apprehend them, for property theft
    (video surveillance of your property and shop and home, with a recorded memory, or a witness or two, helps)
