A few years ago, videos went round claiming to show people opening locked car doors with a tennis ball. If you’ve locked your keys in your car, wouldn’t it be great not to have to phone anyone to come and help, and to just be able to use a tennis ball to gain entry!
The method of opening a car with a tennis ball is simple. Simply cut a hole into the ball and press this as hard as you can against the lock on the door. Pushing into it as hard as you can will send a pressure wave into the door lock which forces it open.
Does it Work?
The answer is categorically no!
Of course, if entering a locked car was as simple as this, it’d make thieves’ jobs a lot easier. Cars are designed to be hard to get into without the correct key.
Opening a car with a tennis ball was even featured in the TV show Mythbusters. When it didn’t work, they took the same principle behind it – air pressure – and applied 100psi to the door lock. This still didn’t work.
So for now, if you’ve locked your keys in the car, you’d better call in a trusted auto locksmith!
