🔧 PRO TIP
The 2020 Envision is first-gen (2016-2020), and every single trim sold in North America runs the full PEPS proximity system with push-button start. There was no base-trim keyed ignition option here. The fob is FCC HYQ4AA, 315 MHz, CR2032 battery, with an HU100 emergency blade inside. If you get "No Remote Detected" on the DIC, swap the CR2032 first. A dying battery drops the polling range fast and the passive entry on the door handles goes out before the start button does.

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

Over in Sunset Hills Country Club in Thousand Oaks, a guy had just closed on a used 2020 Buick Envision. One key came with the deal. The seller told him to get a spare made before something goes wrong. Good advice.

He called the Buick dealer. They told him to bring the car in, leave it for a few hours, and they would order the fob and program it. The quote made him start looking around.

I met him at the bank lot where they had signed the papers. The car was still warm. His original key was the standard GM HYQ4AA smart fob, part number 13584500, with the HU100 emergency insert blade. I pulled my HU100 Lishi, decoded the lock on the driver door, and confirmed the blade cuts. Then I cut the spare on the spot and connected my IM608 II through the OBD port to register the new fob to the body control module.

GM's procedure on these is clean. The BCM on the 2020 Envision is the Continental part, and it accepts new key registration through the diagnostic port without a timed lockout as long as a working key is present. Took about 20 minutes total, cutting included.

We tested lock, unlock, passive entry on both front handles, remote start, and push-button ignition. Both fobs behaved identically. He drove home with a spare in his kitchen drawer and paid a fraction of what the dealer wanted.

Buick Envision Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 2020 Buick Envision key fob use, and how do I change it?
CR2032. Standard coin cell, available anywhere. To open the fob, slide the release button on the back and pull the emergency HU100 blade out. That exposes a seam. Use a flat tool to separate the two halves gently. The CR2032 sits right inside with the positive side facing up. Pop the old one out, drop the new one in the same orientation, and snap the case back together. If the fob range felt short before the swap, the new battery should bring it back immediately.
What is the FCC ID on the 2020 Buick Envision key and why does it matter?
Do I need to bring my 2020 Envision somewhere for a replacement smart key?
My Envision shows "No Remote Detected" but the key fob battery is new. What is going on?
Can I program a new 2020 Buick Envision smart key myself at home?
