Replacement Proximity Fob for GMC Terrain 2018-2019

This three-button proximity fob replaces the original keyless entry remote for GMC Terrain models from 2018 and 2019. It operates at 315MHz and carries FCC ID HYQ1AA and part number 13591388. The unit includes a built-in transponder chip and a physical door key blade. It is a complete non-OEM assembly, not a shell.

Battery-Powered Operation With CR2032 Cell

The fob runs on an included CR2032 coin cell that supplies 3V power for wireless locking, unlocking and panic functions. The plastic and metal housing measures 6.5 by 4.1cm (2.53 by 1.61 inches). There are no rechargeable components or additional power requirements. Normal use draws minimal current from the button cell.

Upgrades a Lost or Damaged Factory Remote

This fob substitutes a missing or broken factory proximity key for the listed Terrain years. It adds a spare remote when a working fob is already present, because programming requires an existing programmed key. The jump is worthwhile only when the vehicle accepts the 315MHz frequency and the owner can arrange locksmith or dealer programming and key cutting.

Questions about this item

How do I install the HYQ1AA fob on my 2018 GMC Terrain, and what step is often missed?

A qualified locksmith or dealership must program the remote and cut the door key; the step people miss is confirming the fob can be programmed to the vehicle before the key is cut, otherwise the physical key may not work.

What maintenance will this proximity fob need later?

Replace the CR2032 coin cell battery when range or response slows; the battery is included new and sits inside the black plastic-and-metal housing.

What limit appears first during sustained use of the 315MHz remote?

The CR2032 cell depletes with repeated lock, unlock and panic presses, reducing wireless range until the battery is swapped.
