🔧 PRO TIP
The 2003 Aurora uses GM's PassLock II system, not a traditional transponder chip. The security sensor lives inside the lock cylinder itself, reading a resistor value on the lock housing. The key blank is a B99/P1113, and despite what some parts lists say, there is no RFID transponder in the key head. If your "SECURITY" light is flashing and the car cranks but won't fire, the issue is almost always the PassLock sensor or its wiring, not the key.

2003 Oldsmobile Aurora Transponder Key Replacement - Fast, Affordable & Professional

Got a call from a guy over in Skofield Park in Santa Barbara. His 2003 Aurora was sitting in his driveway doing the thing these cars are known for: crank, no start, SECURITY light flashing on the dash.

He had already tried the 10-minute relearn twice. Turned the key to ON, waited for the light to go off, turned it back, repeated three times. The internet told him that would fix it. It didn't.

I got there in about 20 minutes. Checked the lock cylinder first. The PassLock II sensor was reading intermittently, which is the number one failure point on these second-gen Auroras. The resistor value was drifting, so the BCM kept rejecting the start signal. Classic.

Cut a fresh B99 key on my portable machine, then ran the PassLock relearn through the OBD-II port with my diagnostic tool. That locks in the correct resistance value to the BCM so the car stops second-guessing itself. Whole thing took maybe 25 minutes from the time I pulled up.

He said he had been reading forums for two days trying to figure out if he needed a new ignition cylinder or a whole new BCM. Neither. Just the right relearn procedure done with the right equipment.

The dealer had quoted him days of wait time and wanted the car towed in. He drove it to dinner that night instead.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

Oldsmobile Aurora Mobile Service FAQ

Real costs, no dealer surprises

Do you use OEM or aftermarket keys for a 2003 Oldsmobile Aurora?
The 2003 Aurora uses a standard mechanical key, B99 profile, with no transponder chip inside the head. The security is handled by the PassLock II sensor in the lock cylinder, not by the key itself. We cut from OEM-spec B99 blanks (P1113) that match the factory depth and spacing. As long as the mechanical cut is right and the PassLock sensor reads correctly, the key works. There is no chip to program in the key head, so "aftermarket vs. OEM" comes down to the quality of the brass and the cut, and ours hold up.
How long will a replacement key for my 2003 Aurora last?
What if my new key stops starting the car after a few weeks?
Can I do the 10-minute PassLock relearn myself on my 2003 Aurora?
Is the 2003 Aurora key system the same as other GM cars from that era?
