I took my car to a shop to replace my Radiator. When I got my car back, I noticed that my Key's Panic button had been tampered with and it was not working at all. it appeared something was missing inside. I know the system worked,prior to sending it, because a week earlier I had mistakenly pushed the panic on the key which set off the alarm and scared the hell out of me. What could the shop have done? This is not a dealer.
Was my my Key's remote system tampered with? on 2002 Mercedes-Benz ML320
