This device could be a thieves new best friend. It’s called the Electronic Key Impressioner. You insert it into a car door and it scans the position of the tumblers inside. It then sends that info back to a PC over USB when you are told the car’s model, which can provide the necessary information to cut the perfect key on the first try.
At the moment, it only works on Fords with simple metal keys, but the hope is to expand it so that it supports other manufacturers and maybe even electronic keys someday soon. It’s for locksmiths and authorized security professionals, but thieves will be using it as well, we are sure.
