I have never heard of that......basically, it's not the Theftlock that is the problem, it's the VIN # that is programmed into the radio.....if it doesn't match the VIN of the car, then there are communication problems....
As for the LED's, they don't usually burnout, they last forever.....it's the circuit board that feeds them that is the problem.....sometimes it's just a soldered joint, sometimes it's the board itself....
