TextEnvista Key Tech by Generation
1st Generation (BPGX)
Single key generation on this nameplate so far. Five-button proximity smart fob with a Philips ID 46 GM EXT transponder under the plastic, push-to-start across every single trim, GM server-authenticated immobilizer behind it. Programming demands a live secure connection to GM during the session; no offline shortcuts exist. FCC ID HYQ4ES, CR2032 cell powering the remote half.
Which Envista Fob Do You Have?
Proximity smart fob that lives in your pocket through the whole drive. Approach the door, the SUV unlocks at the handle, dash button cranks the engine. A short emergency blade tucks inside the housing, but realistically it stays put for years.

Key Fob Battery Drain
Fob behaves at 8 AM, SUV ignores it by mid-afternoon. The 2024 Envista runs hard on CR2032s because remote start and telematics keep waking it. Swap the cell first, two-minute job, three dollars. Drain returns? Marco scopes transmit strength.
Keyless Entry Signal Interference
Strong RF interference is the actual culprit, common near Mission Valley dealer row or Kearny Mesa cell towers. Proximity unlock depends on a clean RF path. Try the lock or unlock button manually; if buttons work, interference is the answer, not a dead key.
Transponder Recognition Delay
First diagnostic is whether the fob cell got swapped recently. The 2024-2025 Envista pauses during push-to-start after a CR2032 swap because the ID 46 chip needs a beat to renegotiate sync. Persists? Marco closes the reprogram in Carmel Valley or Poway.
Can You Self-Program an Envista Key at Home?
Partial path only. Remote functions can be paired in your driveway using the GM door cylinder drill or the ten-minute relearn method if two working fobs already exist. That binds lock, unlock, and remote start buttons. The transponder itself, the half that gates the starter, demands server-authenticated programming through professional kit. Locksmith or dealer for the immobilizer side.

Buick Trivia
Parts trivia worth knowing: your 2024 Envista smart key (part 13547678) shares its HYQ4ES FCC ID and ID 46 transponder with the Buick Encore GX. GM built both nameplates on the same key platform, which means a locksmith with the right server access can program either SUV from the same blank stock and software session. Cross-platform engineering at its quietest.
