🔧 PRO TIP
The 2003 Grand Prix runs GM's Passlock II system, not a traditional transponder chip in the key. The security sensor lives inside the ignition lock cylinder itself and reads a resistive Hall-effect value off the key as it rotates. If the "SECURITY" light stays solid on the dash, the car kills fuel injector pulse and you sit for ten minutes. The Passlock module is part of the BCM, which is behind the lower dash on the driver side. The key blank is B102-P, Strattec part number 690556.

2003 Pontiac Grand Prix Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy at The Collection at RiverPark in Oxnard. His 2003 Grand Prix GT turned over fine but would not fire. Cranked and cranked, the SECURITY light sitting solid on the dash. He had already tried the ten-minute relearn twice in the parking lot. Nothing.

He popped the hood expecting to see a fuel pump relay issue. It was not that.

I pulled up and ran the Passlock II data through the OBD port. The BCM was not seeing a valid resistive signal from the lock cylinder sensor. The key itself was worn down, and the resistive pellet contact was barely making a reading. The BCM saw an out-of-range value every time he turned the key, so it cut the injectors.

Cut a fresh B102-P blank on the HPC Blitz, matched to code. Then ran the Passlock relearn through the Tech2 so the BCM would store the correct resistance window for the new key. That part takes a few minutes of waiting because GM baked a timed security countdown into the procedure.

Tested it three times cold. Fired right up. Tested the remote on the separate fob, locks cycled at range. He stood there watching the dash like the SECURITY light was going to come back on out of spite.

Whole job, done on site, for a fraction of what the dealer quoted him over the phone.

Pontiac Grand Prix Mobile Service FAQ

Real costs, no dealer surprises

How many buttons does the 2003 Pontiac Grand Prix key have?
The key blade itself has zero buttons. On the 2003 Grand Prix, the remote is a separate fob from the key, not built into the head. The fob (FCC ID: KOBLEAR1XT or KOBUT1BT, depending on trim) has three or four buttons: lock, unlock, trunk, and on some models panic. The key is just a mechanical cut B102-P blank with the Passlock II resistive element. A lot of owners do not realize the key and the remote are two completely different systems that have nothing to do with each other electronically.
What security system does the 2003 Grand Prix use and how does it work?
What if my key broke off inside the ignition of my Grand Prix?
My SECURITY light is on and the car cranks but will not start. Is it the key?
Can I do the Passlock relearn myself without any special tools?
