Setup and Programming
The USARemote CWTWB1U345 key fob is designed for user self-programming for specific vehicle years and models. Refer to the detailed programming guide included with your purchase for step-by-step instructions specific to your vehicle's make and model year.
Key Blade Cutting
The included key blade is uncut and requires professional cutting to match your vehicle's ignition. This service can typically be performed by a local locksmith or automotive dealership.
Remote Programming
For vehicles that support self-programming, you will generally need at least one currently working key or remote to initiate the programming sequence. Follow the instructions in the provided guide carefully. If self-programming is not supported for your vehicle's year, or if you encounter difficulties, professional programming by a locksmith or dealership may be required.
Operating Instructions
Once programmed and the key blade is cut, your USARemote key fob will provide the following functions:
- Lock Button: Press once to lock all vehicle doors.
- Unlock Button: Press once to unlock the driver's door, press twice to unlock all doors.

Maintenance
To ensure the longevity and proper functioning of your key fob, observe the following maintenance guidelines:
- Battery Replacement: The key fob uses a standard coin cell battery. When the remote's range decreases or it stops responding, replace the battery. Refer to the included programming guide or consult a professional for battery replacement instructions.
- Avoid Water and Moisture: Do not expose the key fob to water or excessive moisture, as this can damage the internal electronics.
- Protect from Impact: Avoid dropping the key fob or subjecting it to strong impacts.
- Cleanliness: Keep the key fob clean and free from dirt or debris that could interfere with button operation.
Troubleshooting
If your key fob is not functioning as expected, consider the following:
- Remote Not Responding: Check the battery. A weak or dead battery is a common cause of remote malfunction. Replace the battery if necessary.
- Reduced Range: This often indicates a low battery. Replace the battery.
- Intermittent Functionality: Ensure there are no strong radio frequency interferences in the area. If issues persist, try re-programming the key fob using the provided guide.
- Key Blade Issues: If the key blade does not turn in the ignition or door lock, it may not have been cut correctly. Consult a professional locksmith.
If troubleshooting steps do not resolve the issue, please contact USARemote customer support.
