2001 Oldsmobile Silhouette. I have lost my car
key and went to a local GM dealership and bought
a passkey III. I was told since I did not have the
original key the only way to reset the code is to
turn the car on with the passkey and let the alarm
go off three times then insert the passkey again
and hopefully the would change the code.
If that did not work the whole component would
have to be replaced. Is there no other way to start
my van than with this theft deterrent relearn?
Here is the correct procedure. Be sure to follow
exactly, and let me know what happened.
With a master passkey III key (Black), turn ON the
ignition, with the engine OFF.
Observe the Security telltale, after approximately 10
minutes the telltale will turn off.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-3 two more times for a total of 3
cycles or 30 minutes.
Important: The vehicle learns the key transponder
information and/or passwords on the ignition switch
transition from OFF to CRANK. You must turn the
ignition OFF before attempting to start the vehicle.
With a master passkey III key, start the vehicle. The
vehicle has now learned the key transponder
information and the PCM has now learned the fuel
With a scan tool, clear any DTCs.
After a key has been learned, you can add other
keys by starting van with the newly learned key, turn
off, install a new key to be learned, turn ignition to
ON position(not crank) for 5 seconds, then forward
