The video above depicts how to unlock a car with a tennis ball. Based on the demo you can apparently use the air pressure in the tennis ball to push the locking mechanism into position. It’s obviously instructional only! Do not attempt this on any car besides your own, in the case that you locked your keys out of the car. Might be a fake. Let us know the results if you’ve tried it.

This is just a video trick. The Mythbusters gave this one a thorough go-over and couldn’t even replicate it with a shop compressor sealed to the lock.

You cant unlock it by the air, it have to turn to unlock the mechnisim, so this is not true,

Yep, it’s a fake.

That’s a joke movie someone made for a romanian forum to fool newbies to push till they bend the door and break the lock.
The movie is shot in romania (you can see lots of romanian Dacias in the background and the car is a Dacia Logan).

The video is fake, BUT, it does unlock cars with vacuum operated door locks, which include some mid ’70s Mercedes.

This is no trick, at least it works on old Ford cars. I once opened my uncles Ford Granada with a sink plunger.

I’m sure I’m echoing everyone else here, but this is, frankly, crap. I work as a locksmith, and I’ve torn down the door of a car before. You can’t move a car door’s lock linkage with air pressure, it’s a metal rod. Also, the air pressure inside the door (which is not airtight, by the way) would only increase fractionally by the addition of the air inside the tennis ball, no matter how hard you push on it. It’s bollocks.
