What kind of changes does a police department usually make to their cars when they take them out of service and sell at auction?? I know they usually take out equipment and lights, but what about the chip?? Do they reprogram it or just take it out? I have what used to be a detectives or higher ups car, it didn't have any lights, antennas, or equipment mounting done to the car, so I wonder if I still have a chip?!?! How can I find out?? If I don't have one, where can I get one?? Thanks.
