🔧 PRO TIP
The 2003 Century's remote (FCC ID L2C0007T, part 10335582) shares the same circuit board and RF electronics as the Chevy Impala and Pontiac Grand Prix remotes from the same W-body platform. Board number is 15042968. You can literally swap a Buick board into a Chevy or Pontiac shell if the FCC ID and button count match. The logo on the case is cosmetic. The CR2032 is the weak link. When it dies, the remote goes silent, but the physical blade still turns the ignition and the Passlock II sensor in the steering column still reads the key. Remote failure is not an immobilizer failure. Two different systems.

2003 Buick Century Remote Replacement - Fast, Affordable & Professional

Guy got back from a business trip overseas, walked out to long-term parking at the Ventura airport area, and his 2003 Buick Century just sat there. Clicked the remote. Nothing. Clicked again. Dead.

The CR2032 in his L2C0007T fob had drained while the car sat for two weeks. Doors locked, trunk locked, and his emergency blade was buried somewhere in a checked bag he hadn't unzipped yet. He was standing in the lot with luggage and no way into his own car.

He called around. Two shops wanted the car towed in. One offered an appointment next week. Then he found EZ Car Keyz.

I got out to him in under an hour. Picked the door open, popped the hood on the remote right there, and swapped in a fresh CR2032. Then I connected my IM608 to the DLC and pulled the BCM to check remote registration status. His remote was still paired. The Passlock II system in the steering column was reading his key blade fine. The whole problem was a dead battery killing the RF signal, nothing deeper.

I cleared a stale communication fault, tested all three buttons, lock, unlock, trunk, and made sure the range was solid from 30 feet out. Tossed a spare CR2032 in his glovebox.

He drove home that morning. The dealer would have wanted the car brought in and probably quoted him a whole new remote on top of the diagnostic fee. This was a fraction of that, done in a parking lot in Downtown Ventura.

Buick Century Mobile Service FAQ

Real costs, no dealer surprises

How many buttons does the 2003 Buick Century remote have, and what do they do?
Three buttons: lock, unlock, and trunk release. The lock and unlock control all four doors. The trunk button pops the trunk lid without using the key blade. These are standard across the L2C0007T remote regardless of trim level. When you call, I already know the specs for this exact vehicle, so there is no research delay on my end. I show up with the right remote and battery in hand.
What exactly is a remote key, and how is it different from a transponder key?
Can I get a replacement key after hours or on a weekend in Ventura?
My 2003 Century cranks but will not start, and the security light is on. Is it the key?
Can I program a replacement remote myself on a 2003 Buick Century?
