Are there any alternatives to recoding ignition lock cylinder keys after replacing the cylinder?

Answer 1

You have to do a 30 minute "learn procedure" or you can take it to auto zone and they can hook up their scanner to your car, then hook it up to their computer and get the codes, rehook it up to your car and go through a "10 minute Learn Procedure". Here is the one you can do yourself at home: 30-Minute Learn Procedure

# Turn ON the ignition, with the engine OFF . #

# Attempt to start the engine, then release the key to ON. The vehicle will not start. # Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF . # Turn OFF the ignition, and wait 5 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 Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK .

NOTE

The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK . You must turn the ignition OFF before attempting to start the vehicle.

# Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. # With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
