How do I confirm this fob fits my GMC Acadia?

Check three items on your existing remote before ordering: the FCC ID, part number, and transmission frequency. This LYFUCESS fob is made to replace FCC ID: HYQ1EA and fits Part Number 13508275 operating at 433 MHz, specifically for GMC Acadia model years 2017 through 2021.

• Match FCC ID: HYQ1EA printed on your old key.
• Confirm part number 13508275 or equivalent stamping.
• Verify the remote uses 433 MHz frequency on your vehicle's documentation.

What installation and programming steps are required?

The fob arrives uncut and without dealer programming, so a professional must cut the metal blade and program the transponder to your vehicle. Self-programming is not supported—an authorized locksmith or dealer will complete blade cutting and the electronic pairing process.

• Have the key blade cut to match your ignition by a locksmith.
• Have the locksmith or dealer program the transponder into your GMC's system.
• Test remote functions (lock/unlock/panic/proximity start) after programming.
