Re: How could i reset the security lock on a 1999 chevy...
I can't find a reset for that year of Corvette. It is a Passlock system. So maybe the normal 30 minute procedure will work.
Perform the re-learning procedure
- Turn ON the ignition, with the engine OFF.
- Attempt to start the engine, then release the key to ON (vehicle will not start).
- Observe the SECURITY light, after approximately 11 minutes the light will turn OFF.
- Turn OFF the ignition, and wait 10 seconds.
- Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes ( the vehicle is now ready to relearn the Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).
If not, this site may help. http://diy-gm-security.com/
