It is amazing how effective these systems are at keeping owners out of their vehicles? Fortunately there is a relearn procedure you can do yourself. It is a good idea to have a small battery charger connected during this 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 telltale, after approximately ten minutes the telltale will turn off.
Turn off the ignition, and wait five seconds.
Repeat steps one through four two more times for a total of three cycles/thirty minutes, the vehicle is now ready to relearn the Pass-lock(TM) Sensor Data Code and/or passwords on the next ignition switch transition from off to crank.
Start the engine. The vehicle has now learned the Passlock(TM) Sensor Data Code and/or password.
Important: The vehicle learns the Pass-lock(TM) 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.
