Cool trick

Ever lock your keys in the car? You fight with the whole coathanger thing to try and jimmy the lock open and sometimes you have to bite the bullet and call AAA.

Okay, no guy would actually call AAA. You know it and I know it. Anyway.

It turns out that some clever woman has come up with a novel use for the tennis ball on the end of your car's antenna. Check out this video:

For the record, my mother used to lock her keys inside her car about twice a year. I bugged her to get one of those Hide-A-Key things and she promptly locked that inside the car with her keyring. This technique would have proven quite useful to her, except I'm convinced that she would have locked the tennis ball inside the car, too.

Does this actually work? Everytime, any car?

No idea. However, I plan to find out.

I tend to doubt it works well, hard to imagine most car locks are airtight enough to do it, but pretty amazing and clever if it works. Also rather disconcerting if you have a decent stereo or anything else of value in the car.

Opening car door locks with air pressure?

I'm dubious.

My guess is that the guy running the camera just hit the "unlock" button on the key chain.

I'd be interested in your findings.

Or maybe we should just send this one to Mythbusters :-)

Sadly enough I know there is some truth to this from personal experience. In the early 90's I was going through college earning my Bachelors in Law. As part of that I took a class in Investigations. Where the instructor told us about this little trick. But in the 90's he caveatted it with, "This will work on some cars, but newer ones with power locks it tends to not work on too well".
