If your Kenwood KDC-BT645U radio is in protect mode and the reset button is not working, there are a few steps you can try to resolve the issue.

Check the wiring connections: Make sure all of the wiring connections between the radio and the vehicle are securely connected and not loose or corroded.
Check the speaker wiring: Make sure the wiring for the speakers is not damaged or loose.
Check the fuse: Make sure the fuse for the radio is not blown.
Check the power supply: Make sure the radio is receiving power from the vehicle's battery.
Try a different power source: If you have access to another vehicle, try connecting the radio to it to see if it works.
Consult the manual: Check the manual for troubleshooting steps or contact the manufacturer for further assistance.
Try a professional service: If none of the above steps resolve the issue, it may be best to take the vehicle to a professional audio technician or mechanic for further diagnosis and repair.
