🔧 PRO TIP
The 2020 Encore GX runs on GM's newer communication architecture, and not every programming tool on the market has kept up with it. This catches some locksmiths off guard. If a tech shows up and their equipment won't talk to the car, it's not the car's fault and it's not yours either. Just call someone with updated tools. The fob carries a CR2032, so before you assume the key itself is failing, seat a fresh battery properly and make sure the contact clips haven't spread. A loose battery in these fobs can mimic a dead fob or even a programming failure. Also worth knowing: the Encore GX is a different vehicle from the original Encore, and the key systems are not interchangeable. Make sure whoever is cutting and programming your key knows which one they're working on.

2020 Buick Encore Gx Smart Key Replacement - Fast, Affordable & Professional

A guy in Downtown Lemon Grove called me on a Tuesday afternoon. He'd been at a small get-together near the park, set his key down somewhere, and by the time he realized it was gone, he'd already walked the whole area twice. Nothing. His 2020 Buick Encore GX was sitting at the curb and he had no backup.

He'd already called the dealer. They told him to tow it in, they'd get to it when they could, and he should plan on the next day at the earliest. He was not interested in any of that.

I came out to him in Downtown Lemon Grove. All-keys-lost on this generation of GM smart key is a job that requires diagnostic equipment and a timed security sequence through the OBD port. The system has to clear the lost fob from memory and enroll the new one from scratch. There's a countdown built into the process, so even when everything is going right, you're watching a progress bar and waiting. That's normal. I've done enough of these to know not to rush it.

Once the sequence finished, I verified remote operation, confirmed the engine started and held, and tested every button on the fob before I packed up.

He saved a good chunk compared to what the dealer quoted, and he didn't lose his car for a day and a half over it.

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

“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.”
