🔧 PRO TIP
The 2004 Buick Century runs a remote with a physical blade and a transponder chip inside the head. The remote side handles lock, unlock, and trunk. The chip side talks to the immobilizer so the engine actually runs. These are two separate functions in one unit, and both have to work. A lot of owners replace the fob thinking that fixes everything, then wonder why the car still won't start. If the blade turns and the engine cranks but immediately dies, that points to the transponder side, not the buttons. The CR2032 powers the remote buttons only. A dead battery kills your range and your lock/unlock, but it does not kill the chip. Worth keeping that straight before you buy anything.

2004 Buick Century Remote Replacement - Fast, Affordable & Professional

Cardiff-by-the-Sea sits right on the water, but Encinitas stretches east, and some of those properties are on long gravel roads that no flatbed driver is excited about.

A caretaker managing one of those estates called me on a weekday afternoon. He had a 2004 Buick Century parked at the gate of the property. The remote had been getting flaky for a week, and that morning it stopped working entirely. Not just short range. Nothing. The blade still turned, but he had no remote function at all, and he wasn't sure the car was going to start reliably much longer. The nearest dealer was over an hour away, and even talking to them on the phone he was looking at scheduling out days, plus the question of how to get the car there in the first place.

He texted me his pin. I loaded everything I needed for that specific vehicle and drove out.

When I got there I went through it in order. Checked the existing remote, confirmed the chip was still communicating, isolated the problem to the remote electronics. Built him a new unit on site, cut the blade to his vehicle, programmed the transponder, and synced the remote to the car right there at the gate. Then I walked every button and the trunk release before I called it done.

Car started. Remote worked. He was back to work in under an hour.

The dealer conversation, just the phone call, had already taken longer than the actual job.

Buick Century Mobile Service FAQ

Real costs, no dealer surprises

How many buttons does the 2004 Buick Century key fob have?
Three buttons. Lock, unlock, and trunk release. The factory fob for this vehicle is a 3-button remote with a blade that operates the ignition and door locks manually. When you call, we already have the specs on file for the Century, so there's no back and forth trying to figure out what you need.
What exactly is a "remote" key and what does it do on this car?
What if I need a replacement key after hours or on a weekend?
My 2004 Century starts fine but the remote buttons stopped working. Do I need a whole new key?
Can I buy a replacement fob online and program it myself?
