Code scanners?

I wouldn't say it's impossbile, but it doesn't make sense. Also, since your girlfriend's car is much newer than yours, I would somehow doubt that the same scanner could be used to open them both. If someone had the money to buy, and the technical savvy to operate this code scanner.........would he really need to be out stealing radios? I used to drive tow trucks for a living, and naturally we often had to unlock cars.......either the owner was locked out, or we were towing the car away for trespassing, the owner wasn't present, and we needed to get inside to release the parking brake or whatever. Of course accidents happen sometimes, but in general, the idea was that we'd get the car open without breaking or damaging anything..........I don't see any reason the same thing couldn't have happened to your car and your girlfriend's. You said that on your Grand Marquis, ALL the doors were unlocked, right? That would suggest a few things: 1. There were two thieves. The first thief gained access to one door, then used the power unlock to let his buddy get in the other side. 2. (More likely) The thief used some sort of long rod or stick to push the "power unlock" button on the door panel, rather than manipulating the lock mechanism itself, and that's why all of them were unlocked. He would have wedged something between the door frame and the body of the car, and then dropped the tool inside.........open both front doors, and look for fresh scratches around the door frame, or damage to the weatherstripping. 3. Do either of the cars have the optional keyless entry keypad on the exterior of the driver's door? On Fords, there is one permanent code for that keypad, set from the factory, and you can also add your own new, custom code. The original code is printed on the brain of the factory keyless entry module. It would be entirely possible for the car's previous owner (or anyone who had access to the car to learn the code) to use the keypad to open the doors.
