SUPALAND Keyless Entry Remote Start Key Fob for GMC Terrain 2018-2022 HYQ1AA 315 MHz — Preinstalled Battery & Circuit Board

SUPALAND's keyless entry remote start key fob is a ready-to-program replacement designed to match GMC Terrain models from 2018 through 2022 (FCC ID HYQ1AA, 315 MHz).

This SUPALAND remote fob arrives with electronics and a battery already installed so it's prepared for professional programming right out of the box. It mirrors the factory remote's button layout and communicates on the same 315 MHz frequency, making it a practical hardware replacement when an original fob is lost, damaged, or needs an extra spare. Note that a locksmith or dealership must complete the programming and the uncut metal key blade will require local cutting to match your vehicle.

How will this fob match my GMC Terrain's original remote?

The SUPALAND unit is built to the same functional specifications as the factory HYQ1AA key fob and supports the corresponding part number 13584512. Button positions, signal frequency, and internal electronics are preinstalled to replicate original behavior once programmed by a professional.

• Compatible with FCC ID HYQ1AA and 315 MHz signal frequency.
• Designed to fit GMC Terrain years 2018–2022.
• Supplies the same button layout for lock, unlock, remote start, and panic functions.
• Pre-installed battery and circuit board for immediate programming readiness.

What setup steps are required after I receive it?

SUPALAND ships this replacement key fob pre-assembled with its battery and electronics, but it cannot be vehicle-programmed at home in most cases. You will need a certified locksmith or your dealership to perform the immobilizer pairing; the metal blade arrives uncut and must be cut to your vehicle's key profile by a local locksmith or hardware service.

• Take the fob to a locksmith or dealership for immobilizer programming.
• Have the uncut key blade cut to match your vehicle's ignition/cabinet key.
• Confirm the locksmith can program HYQ1AA / 315 MHz remotes for GMC vehicles.
• Test lock/unlock/remote start/panic functions immediately after programming.

Is this product reliable and ready to use out of the box?

Every SUPALAND key fob is tested with professional locksmith tools before shipping to ensure the electronics and battery operate correctly. While the unit is factory equipped and inspected, programming and cutting are still required to make it functional with your specific vehicle.

• Each fob undergoes functionality checks prior to shipping.
• Battery and circuit board are pre-installed for convenience.
• Arrives complete with electronics but not programmed to your car.
• Packing includes one ready-to-program key fob per order.

Which part numbers and frequencies should I verify before ordering?

Confirm your vehicle’s original remote uses FCC ID HYQ1AA and transmits on 315 MHz, and that the factory part number matches or is cross-referenced to 13584512. These details ensure the replacement will be compatible with your GMC Terrain’s receiver and immobilizer system.

• Verify vehicle compatibility for GMC Terrain model years 2018–2022.
• Confirm FCC ID HYQ1AA and 315 MHz frequency match your original fob.
• Check part number 13584512 as the cross-reference for replacement fitment.
• Use the vehicle fitment tool or owner's manual for additional verification.
