Password must be learned when Passlock™ sensor, BCM or PCM is replaced. BCM must be programmed with proper RPO configurations before performing relearn procedures. If PCM is replaced, after programming, PCM will immediately learn the first password it receives. If password needs to be changed, learn procedure will need to be performed.

If Passlock™ sensor was replaced, SECURITY indicator light will flash for 10 minutes. If Passlock™ module was replaced, SECURITY indicator light will flash for a few seconds, then stay on for 10 minutes. If PCM was replaced, vehicle may start and procedure may not be needed. If replacement PCM was used even momentarily, SECURITY indicator light will flash for a few seconds, then stay on for 10 minutes. After 10 minutes, when light turns off, turn ignition switch to OFF position for 5 seconds.
