SUPALAND Keyless Entry Remote Key Fob Replacement Fits GMC Terrain 2010–2021 — 2-Pack, Battery Pre‑installed

SUPALAND's pre-tested keyless entry remote is a ready-to-program OEM-style replacement for compatible GMC, Buick and Chevrolet models, arriving with battery and electronics already installed.

If your factory key fob is lost, damaged, or the buttons no longer respond, this SUPALAND replacement fob offers a cost-effective way to restore remote locking, trunk release and remote start functions for supported vehicles. Each unit ships as a complete electronics module with battery installed and includes two fobs per order — both designed to accept programming using one working key and a local locksmith’s blade cut for the physical key portion.

How easy is setup and programming?

Each replacement comes pre-installed with the battery and electronic board so you can program the fob without opening the case.

What functions does this replacement remote support?

The SUPALAND key fob duplicates the standard remote functions of the original unit so you can lock/unlock doors, open the trunk, and use remote start when supported by the vehicle’s system. Buttons are mapped to the same signals as the factory key and the internal electronics are matched to the vehicle’s receiver protocols.

• Remote lock/unlock and trunk release where applicable.
• Remote start compatibility depends on factory vehicle equipment.
• Fully assembled with button contacts and electronics in place.
• Two fobs included so you have a spare ready to program.

If the unit fails or is incompatible despite correct fitment data, check the return policy and contact support for troubleshooting or replacement options.

• Pre-tested for electronics and battery performance before shipping.
