Replacement Key Fob for GMC Terrain 2018-2020

This replacement keyless entry remote operates at 315MHz with FCC ID HYQ1AA. It matches part number 13584502 and fits GMC Terrain models from 2018 to 2020. The unit includes five buttons for lock, unlock, remote start, trunk release and panic functions. A CR2032 lithium battery is supplied inside the black plastic and metal housing.

Reliable Operation Across Daily Use

The remote transmits on a fixed 315MHz frequency to communicate with the vehicle security system. Each button press sends a coded signal that the receiver validates before acting. The CR2032 cell provides consistent voltage for repeated transmissions over an extended period. Performance remains stable as long as the battery retains sufficient charge and the fob is kept free of damage.

Aftermarket Alternative to Factory Remote

This non-OEM accessory replaces a lost or worn factory key fob when the part number and FCC ID match exactly. It requires professional programming and key cutting by a qualified locksmith or dealership before use. The upgrade is worthwhile only when the original remote is unavailable or uneconomical to source. Buyers who cannot confirm programming compatibility or who need an OEM-certified unit should not purchase this product.

Questions about this item

Does the 315 MHz signal draw noticeable power from the CR2032 battery during daily use?

The remote uses a standard CR2032 lithium coin cell; typical current draw is very low so the battery lasts months under normal operation.

What tools or access does a locksmith need to programme the HYQ1AA fob to a 2018-2020 GMC Terrain?

A qualified locksmith or dealer with the correct diagnostic equipment must programme the remote and cut the mechanical key blade to match the vehicle.

Will this five-button remote work alongside an original factory fob already paired to the same Terrain?

Yes, once programmed the replacement operates independently and coexists with any existing factory remotes on the vehicle.
