If you’re looking to unlock a car with a tennis ball, there are a few things you’ll need. The first is a tennis ball. The second is some patience. And the third is some skill. Here’s how to do it:

  1. Find the car’s immobilizer key. This is usually located on the inside of the door handle or near the key fob.
  2. Place the tennis ball in between the immobilizer key and the car’s door handle.
  3. Use your other hand to twist the immobilizer key until it pops out of place.
  4. Open the door of the car and remove the tennis ball from between its bars.
