What happens in the movies can't always be accomplished in real life. For instance, jumping out of a window in a movie looks easy, but if you try it for yourself, you might not walk away like that cute actor did.

If you have seen someone (whether in reality or not) open a door with a credit card, then you may want to keep that particular ability in the front of your memory, as it really can help you to get in your house if you have misplaced your key.

Keep in mind that you really have to work hard to make the credit card open the lock, so you may want to use an old beat up credit card or gift card that is no longer valid.

Patience is the key to getting the door opened, so be careful that your neighbors don't call the police if they happen to see you jimmying the lock.

Follow the instructions wikiHow provides, and you should be back in your house in no time. If you happened to lose your key to your combination lock, Francesca can tell you how to figure out the combination, and Brian tells you how to crack a Master combination lock.
