🔧 PRO TIP
The 1999 Sunfire runs GM's VATS (Vehicle Anti-Theft System), also called Passlock or PASSKey, depending on trim and build date. This is not a transponder chip system. The ignition lock cylinder has a resistor-based hall effect sensor that reads a magnetic code from the key's sidebar. If that sensor drifts or the wiring from the lock cylinder to the Body Control Module (BCM, part number varies but often GM 09364981 or 16236195) corrodes, you get a "SECURITY" light on the dash and a no-start. The key itself might be perfectly fine. Check the sensor harness at the ignition connector first.

1999 Pontiac Sunfire MECHANICAL-KEY Replacement - Fast, Affordable & Professional

Got a call from a guy in the Midtown neighborhood in Ventura who had two cars in the driveway and zero working keys between them. One was a 1999 Pontiac Sunfire, the other was his wife's car. He wanted both handled in one visit.

The Sunfire was the simpler one, and also the more annoying one. Previous owner had given him one key that was so worn the sidebar was almost flat. It still turned the ignition, barely, but it had started triggering the SECURITY light on cold mornings. Ten-minute lockout every time while the Passlock system timed out and reset.

I checked the key against the lock cylinder and it was basically skating through without proper engagement. Cut a fresh B102 blank on the HPC to factory bitting, matched the sidebar cuts, and tested it in the ignition, doors, and trunk. SECURITY light stayed off. Cranked clean on the first turn.

Then I moved to the second car in the driveway, different key blank, different system, same setup and tooling already on site.

The whole visit took under an hour for both vehicles. He told me the dealer quoted him separate appointments on separate days, with a tow for the Sunfire since it was intermittently not starting. He just shook his head and said he wished he had called sooner. That is the part of this job I never get tired of hearing.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Pontiac Sunfire Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 1999 Pontiac Sunfire key use?
None. The 1999 Sunfire uses a plain mechanical key, no transponder chip, no fob, no battery. It is a double-sided B102 key blank that operates the ignition, doors, and trunk purely by mechanical cut and the Passlock sidebar profile. Some owners confuse this with a transponder setup because the SECURITY light comes on, but that light is tied to the Passlock sensor inside the ignition lock cylinder, not to anything in the key itself. There is nothing electronic in the key to power.
Is there an FCC ID for the 1999 Pontiac Sunfire key?
Do I need to tow my Sunfire somewhere for a replacement key?
My Sunfire shows the SECURITY light and won't start. Is the key bad?
Can I get a copy of my Sunfire key at a hardware store?
