What is happening to your QY-5002 Clarion radio?
The symptoms help describe the problem. We confirm the cause after checking the module.
“Personal Lock” message
The screen asks for a “Personal Code” and the unit does not work. This is an anti-theft lock that activates after a power interruption, for example after a flat battery. We can read the original code or remove the lock, according to your preference.
Radio locked after power disconnection
After the battery is disconnected or runs flat, the radio stops working: there is no access to navigation, radio, CD or settings. This is the Personal Lock protection in action. We check the module, unlock it or permanently remove the lock, and test the operation.
