Re: Unlock your car with a tennis ball?
Total BS here. Although you can unlock a Mazda 3 by hitting the door in the right place. You can also break into a Crown Vic or Grand Marquis by pulling off the body molding and poking a screw driver into the hole.
Another good one is the '97-03 F-150, Expedition, Navigator. This one, Ford should be embarrassed about and is COMMON knowledge to dealers (ME) and the Police, so I don't so a problem with sharing it. Lift up the Driver's door handle and look up from underneath it. You will see a small square/rectangle hole that is about 1/4 to 3/8th inch wide. It basically lines up with the lock ****/shaft. Well, all you have to do is put a long screw driver in the hole and push the lock up and open the door. If you get it once, you will only need about 5 seconds to do it again and again.
Another weak security link to these same vehicles, and most other Fords are that they only have between 16 and 32 possible Key Cuts depending on the specific model. It would only take a thief, with all the possible keys, about a minute to try each one and get in. Ford didn't see this as a security risk for vehicle theft, because of the code hopping sentry keys with the started interrupt feature. That may be true, but it doesn't help you if all they want is your stereo, or other valuables left inside. It you own one of these trucks, try the screwdriver thing, it's obscenely easy...
