Setup and Programming
Proper setup of your new key fob involves two main steps: cutting the physical key blade and programming the remote functions to your vehicle.
1. Key Blade Cutting
The key fob includes a blank key blade (visible in the product overview image). This blade must be cut by a qualified professional (e.g., a locksmith) to match your vehicle's existing key. This allows for manual entry into the vehicle if the remote battery is dead or if remote functions are not working.
2. Remote Programming
Important: This key fob requires professional programming. It cannot be self-programmed by the user. You will need to take your vehicle and the new key fob to a dealership or a certified automotive locksmith for programming. They have the specialized equipment and software required to link the key fob to your vehicle's security system.
Refer to your vehicle's owner's manual for specific instructions on key fob programming, as procedures can vary by model year. While some vehicles may have self-programming options for certain key fobs, this specific model (M3N5WY7777A) typically requires professional assistance.

Operating Instructions
Once programmed, your key fob will allow you to control various functions of your Chevrolet Corvette:
- Lock Button: Press once to lock all vehicle doors.

Maintenance
The key fob is powered by an internal battery. When the battery is low, the remote's range may decrease, or it may stop functioning. To replace the battery:
- Carefully open the key fob casing. Refer to your vehicle's owner's manual or a reliable online resource for specific instructions on opening your Corvette's key fob model.
- Note the type and orientation of the existing battery.
- Remove the old battery and insert a new one of the same type, ensuring correct polarity.
- Close the key fob casing securely.
Regularly inspect the key fob for any physical damage or wear. Keep it away from extreme temperatures and moisture.
