What comes in the package and is anything missing?

This KEYECU remote is supplied as a complete replacement assembly with the major components included, so it functions like the factory fob once programmed. The metal blade arrives uncut and requires a locksmith or dealer to cut it to your vehicle key profile.

• Included: key shell, circuit board, preinstalled 4A transponder chip, battery, uncut metal blade.

• Ready to program to your vehicle after cutting the blade.

How do I program and activate this replacement remote?

The KEYECU fob must be programmed to your vehicle and the metal blade must be cut to match your ignition; these steps are typically performed by a locksmith or the dealership. Programming procedures vary by year and trim, so use a professional to ensure the remote and transponder are synchronized with your vehicle’s security system.

• Bring the fob and vehicle to a qualified locksmith or GMC dealer.
• Provide proof of ownership if requested by the dealer for security purposes.
• Expect both blade cutting and electronic programming services to be required.

What should I check before ordering to avoid returns?

Double-check your current key’s appearance and the part information before purchasing — the wrong frequency or part number will prevent the remote from working even after programming. If unsure, open your original fob to view the circuit board or consult the dealer with your vehicle VIN for certainty.

• Verify button layout and shell shape visually against your original key.
• Open the original fob to confirm frequency/part number printed on the circuit board.
• If the original key is missing, contact your dealership for the correct key code and compatibility.
