30-Minute Learn Procedure

WARNING: This page is about a different car, the 2003 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

Use this procedure after replacing the Passkey(R) III (PK3) keys, theft deterrent control module or PCM.

NOTE: This procedure is not available on vehicles equipped with option code Z49 or BAE.

NOTE: If replacing a theft deterrent control module with an GM SPO replacement part, perform the procedure to setup a new theft deterrent control module prior to the 30-minute relearn procedure.

With a master Passkey(R) III key (Black), turn ignition on, with engine off.
Observe the SECURITY telltale. After about 10 minutes, the telltale will turn off.
Turn OFF ignition, and wait 5 seconds.
Repeat steps 1 through 3 for 2 more times for a total of 3 cycles or 30 minutes.

NOTE: The vehicle learns the key transponder information and/or passwords on ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the engine.

With a master Passkey(R) III key, start engine. The vehicle has now learned the key transponder information and PCM has now learned the fuel continue password.
Using scan tool, clear any DTCs.
