Opening Your Door With a Credit Card.
As those of you who have read my previous posts may have noticed, I like to take a look back at the lock opening methods employed by eighties movies and probably some of today’s shows. You have probably all seen movies or television shows where someone breaks into a home or office using a credit card to pry open the lock.
So what is the methodology behind it? In the simplest form you take a credit card or similar plastic card (i.e. Gift card, library card, shopping rewards card) and insert it in the crack of between the door lock and the doorframe. Your goal is to be able to insert the card and move it in a fashion that will push down the latch of the lock. The direction of the latch will also affect how fast you can accomplish this feat. If the slanted side of the latch is facing you, you will have an easier time than if it was opposite you. While you are working the card, you can lean on the door to add a little pressure. If done right, you will eventually push the latch down and be able to open the door. If there is trim on the doorframe or other obstructions, you may not be able to employ this lock picking method. This method is only intended for spring loaded doorknob locks and will not work on heavier locks like deadbolts.
Again, attempting to open any doors that you are not the owner of is illegal and should not be done. If you want to practice these techniques, do it in your own home.
Here is a video demonstrating the opening of a door lock with a credit card.
