I came out to the my 1998 Buick Park Avenue from voting this morning and it would not start. The dash said unknown driver yet the FOB would unlock the doors. The starter would click, but not turn the engine over. I disconnected the battery for several minutes, but there was no change. After trying several different things the car will not do anything now. The electrical has completely shut down. No starter clicking. Very few dash lights or radio now. I walked home and got my other FOB and it's the same way ...... nothing! These FOB's are a couple of years old now. I bought them new and programmed them. I tried the exact same procedure to program them, but the car will not respond with Lock/Unlock doors like it should when I hold both button down for 30 seconds. See procedure below. I'm wondering if I need to clear some codes? Anything else I might try? 1996 – 1999 Park Avenue FOB Programming 1 Turn OFF the ignition switch. 2 Use a fused jumper wire in order to connect the data link connector terminal 8 (BLK/WHT) to terminal 4 (BLK). 3 Close all of the doors. 4 Turn ON the ignition switch.
