Frequently Asked Questions

1. Where is the FCC ID located on my GMC smart key?
The FCC ID is usually printed on the back cover of your remote. For newer "brick" style remotes, you may need to remove the emergency key blade to see the ID inside the slot. Common IDs include M3N-40821302, HYQ1EA, or OHT0106051.

2. Can I program a GMC smart key myself?
Some GMC models allow on-board programming if you already have working keys, but most modern vehicles from 2017+ require professional programming via the OBDII port. We recommend contacting a licensed locksmith or dealer.

3. Does the key include the emergency backup blade?
Yes, all our GMC proximity fobs come with an uncut emergency insert blade. This is essential for manually unlocking your door if the vehicle's battery dies. The blade must be cut by a professional locksmith.

4. Will this work for my Denali or AT4 trim?
Yes, as long as the FCC ID and button configuration match. GMC vehicles with premium trims often include specific features like remote start or power tailgate; ensure the replacement fob has the same icons as your original.

5. Is the battery included?
Absolutely. Every GMC remote head key and smart fob includes a fresh, pre-installed battery (typically CR2032). All units are tested for signal frequency before shipping.
