Fitment and compatibility

For 2017–2020 Buick Envision with the matching five-function factory smart key. Verify the original part number, FCC identifier, frequency, button layout and emergency-blade profile with a qualified locksmith before ordering. Not for a different-frequency HYQ4AA transmitter or conventional keyed ignition. Shared FCC ID alone does not establish interchangeability. Remote start and power liftgate controls operate only when the vehicle already supports those factory features.

Programming

Professional vehicle programming and emergency-key cutting are required before use and are not included. Confirm aftermarket-key programming support with your locksmith. These are unbranded aftermarket replacements, not genuine GM or Buick keys. Detail photographs show one example of the same key design; this package contains two complete remotes.
