Understanding the 20835400 GMC Terrain Key Fob

Programming a New 20835400 GMC Terrain Key Fob
Programming a new 20835400 key fob can sometimes seem daunting, but with the right guidance, it can be done relatively easily. There are two primary methods: using an existing programmed key or utilizing a professional diagnostic tool. We’ll cover both methods in detail.
Programming with an Existing Key
This method requires at least one working key fob. Follow these steps:
- Insert the working key into the ignition and turn it to the “ON” position.
- Press and hold the unlock button on the working key fob until the doors lock and unlock.
- Remove the working key and insert the new unprogrammed key.
- Turn the new key to the “ON” position.
- Press and hold the unlock button on the new key fob until the doors lock and unlock.
- Remove the new key. The programming process is complete.
Programming with a Diagnostic Tool
If you don’t have a working key, you’ll need a professional diagnostic tool, typically available at locksmiths or dealerships. This tool directly interfaces with the vehicle’s computer to program the new key fob.
