San Diego Oldsmobile Bravada Key Replacement (1998-2004)

Two-working-key relearn is the only DIY path, and one key alone will not satisfy it. The 1999 Bravada wants the GM 10-minute VATS sequence: insert key one, turn to RUN, hold ten minutes until the SECURITY light extinguishes, repeat for key two, then add your new pelleted blank. Three cycles, thirty minutes, no scan tool needed but you must have two existing keys. Down to one or zero? That is locksmith territory, requires PIN and tools. Dial (619) 876-1271 and we will run it on-site.

Because the blade is only half the puzzle on a 2003 Bravada. Cutting a key to fit the ignition cylinder is mechanical; making the BCM authorize the engine is electronic. The 2003 runs PK3 with a Megamos 13 transponder, and that chip needs to be programmed through OBD-II with a PIN. Local hardware-store cutters skip that step. We bring the Autel, pull the PIN, program in your driveway, and budget runs $150-$225 all-in.

Three-button remote head key with a VATS-pelleted blade (no transponder chip on the 2001) and a CR2032 cell powering the remote side. Buttons are lock, unlock, and panic. If you can dig up your old fob, even broken, the FCC ID printed inside lets us clone the remote directly to a fresh shell. We pair the new remote to your BCM after the VATS side is squared away, total job runs roughly 25 minutes at your address.

Substantially yes. The 1998-2001 Bravadas sit on the GMT330 chassis with VATS resistor-pellet blades, no chip in the key. The 2002-2003 cars upgraded to PK3 with the Megamos 13 transponder and the remote head key. The 2004 final-year Bravada jumped to the GMT360 chassis but kept PK3 with Megamos 13. Blades are interchangeable in shape across the run, but the security tech and programming procedures are entirely different. Always give us the VIN so we roll out with the right blank and PIN already lined up.
