🔧 PRO TIP
The 2004 Buick Century runs a conventional remote separate from the ignition key. The fob handles lock, unlock, and trunk, while the ignition key is a separate blade that carries a transponder the immobilizer reads. Two pieces, two potential failure points. A lot of owners come to me thinking the fob is dead when it's actually the ignition key side causing a no-start. Keep them straight. The fob battery is a CR2032, and these contact points corrode from sitting in a cup holder near condensation. Before you assume the fob is toast, pop it open and check the contact spring on the positive terminal. It bends inward over time and loses contact with the cell even when the battery tests good.

2004 Buick Century Remote Replacement - Fast, Affordable & Professional

Pacific View parking lot, middle of a school afternoon. A mom called me because she'd been clicking her 2004 Buick Century fob for ten minutes and nothing was happening. Doors wouldn't unlock remotely, trunk button did nothing. She'd already swapped the CR2032 herself, which was the right first move, but it didn't fix it.

When I got there she handed me the fob and I could see right away the battery contact had a slight outward bow. New battery, wrong contact pressure. Classic. I reshaped the spring, reseated the battery, and the fob woke right up. Locks responding, all three buttons working.

Then I did what I always do after any fob fix: I walked the car. I wanted to confirm the ignition key side was reading correctly too, since these older GM vehicles carry the transponder in the key itself, separate from the remote. She started the car, no warning lights, no hesitation. Clean.

The whole thing took maybe twenty minutes in that lot. She'd already called the dealer before she called me, and they'd told her to bring it in and leave it, possibly overnight. She had a kid in the back seat who needed to be somewhere. That overnight option wasn't happening.

She drove off with a working key and change left in her pocket compared to what the dealer quoted.

Buick Century Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 2004 Buick Century key fob use?
CR2032. Standard size, easy to find at any drugstore or hardware store. The swap itself is simple: a small flathead or a coin to pop the fob case, swap the cell, and close it back up. One thing to watch: the positive contact spring inside these fobs can bend slightly when you pry the case. If you swap the battery and the fob still feels weak or inconsistent, open it back up and check that the spring is actually pressing down on the battery face. That bend is a common cause of a "dead" fob that actually has a fresh battery in it. Every key we deliver goes out with a new CR2032 already installed and tested.
I bought a replacement fob online that matches the factory FCC ID. Can I program it myself?
How fast can you get to Pacific View in Ventura?
My 2004 Century starts fine but the remote stopped working. What usually causes that?
Do I need both the remote fob and the ignition key replaced, or can I replace just one?
