Frequently Asked Questions
How do I know if this 5-button remote is correct for my vehicle?
The best way is to match FCC ID: HUFGM2718 on your original remote. This model features the Hatch Glass release; if your vehicle uses a full Power Hatch button instead, you will need the 6-button version.
Can I program this key myself?
No. Starting with 2021 models, GM introduced a Secure Gateway Module with high-security encryption. This proximity remote must be paired using specialized diagnostic equipment by a professional automotive locksmith or dealer.
What does OEM Refurbished mean?
OEM Refurbished means this is a genuine factory remote that has been professionally inspected, cleaned, and tested to ensure full functionality. It offers the reliability of an OEM part at a lower price point than OEM New.
