1996 Pontiac Bonneville 3800 V6 non turbo. Security light. Removed keyless starter remote starter and key security was locking me out for days on end would start when it felt like starting.
Question: why does my security keep locking me out, will not identify key. This thing has a mind of its own will start when it feels like it will work fine for weeks on end and all of a sudden you cant start it for hours or days security light some times blinks and some times steady ?
Answer: This sounds like the common problem with the passkey security system. A common problem is the 2 small wires on the ignition key cylinder break. This causes a loss of key data for the system.
Sometimes tilting the wheel in different positions will enable it to start and give an indication of the broken wires.
