🔧 PRO TIP
The 2020 Buick Encore runs a five-button smart key on a GM security platform. The fob takes a CR2032, which is good because those are easy to find, but here is the thing owners miss: the battery contact tabs inside the fob case can lose tension over time. A fresh CR2032 sitting on a slightly sprung contact reads almost the same as a dying battery to the car. If you swapped the battery and still get a key-not-detected warning or shortened range, pop the case back open and check that the contacts are actually gripping the battery face before assuming the fob is dead or needs programming. Also worth knowing: the 2020 Encore uses a passive entry system, meaning the car looks for the fob when you touch the door handle. If only one door handle is acting up but the others and the start button still see the fob just fine, the fob is almost certainly not the problem. That points to the handle sensor or the wiring at that door, not the key.

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

Buena Creek on a Tuesday afternoon. A woman called me from the parking lot off Olive Avenue because her 2020 Encore had been throwing a key-not-detected warning on and off for two weeks. She had already gone to the dealer, sat there for two hours, and left with a quote for a replacement smart fob plus labor. She had not bought anything yet.

She met me at her car. The fob looked fine externally. I opened it up on my work mat right there in the lot. The CR2032 inside was still showing decent voltage on the meter, but the positive contact tab had a slight outward bow. Just enough to reduce pressure on the battery face. Took about thirty seconds to seat it correctly and get the contact tension back where it should be.

Then I did the actual test, the part that matters. Walked both door handles for passive entry, checked the start button response, tested all five buttons, locked and unlocked from range. Everything behaved.

She asked if I was sure that was it. I told her I was, and that if it came back I would deal with it then, but that a loose battery contact is one of those things that causes exactly this kind of intermittent behavior.

She did not need a new fob. The dealer quote had sounded authoritative. It just was not the right call for what was actually going on with her car.

Buick Encore Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my 2020 Buick Encore?
Call a mobile locksmith before calling the dealer. An all-keys-lost situation on the 2020 Encore means the car has no working fob registered to it and needs a full security reset through the diagnostic port before any new fob can be enrolled. Dealers typically want the car towed to them for that, which adds cost before they even start the job. I come to wherever the car is sitting, handle the security reset and new fob programming on site, and cut the emergency insert blade to match your door cylinder. The price I quote on the phone is what you pay. No tow, no shop labor surprises, no waiting days for an appointment slot. On a job like this, expect somewhere around 45 to 60 minutes including the security reset countdown the system requires.
Can you wipe a lost or stolen fob so it no longer starts my Encore?
Does the smart key for the 2020 Encore have a hidden emergency blade inside it?
I bought a replacement fob online for my 2020 Encore. Can I program it myself?
My Encore starts fine but the passive door handle unlock stopped working on the driver side. Is the fob failing?
