If yes, then worry no more!In this article, we will describe the easiest ways to open a locked door. This tutorial will help you break into your house without using any tools, except for your credit card. What You Need For this tutorial, you won’t need power and hand tools. Only a single item can do the work. However, you must follow the tips below to avoid breaking your card or failing to pick a door lock with a credit card.As much as possible, use a card that you don’t mind bending or damaging since it may be scratched or bent during the tutorial. You can use a membership card, a gift card, or any thick plastic card. Make sure, though, that the card is flexible enough to be inserted between the crack of the door and sturdy enough to push the metal latch of the lock. Can you open a deadbolt with a credit card? A deadbolt is more about resisting kicking open or using a credit card to slide in and raise the bolt. It's not so much about being harder to pick, as the lock mechanism in it is going to be extremely similar to a normal door handle lock. However, bump keys can make most traditional locks quite easy to open. Install a door latch guard. This metal plate follows the contour of the door frame, extending over it. It is designed to prevent someone from sliding a credit card into the space between the door and the frame.Use a dead bolt on your door. A dead bolt is a much longer piece of metal—or bolt—that is inserted far into the door frame, whereas a door handle lock only uses the small piece of metal that can be moved with a credit card. Install additional dead bolts on your door for extra security. At lockpickmall.com, we offer lock pick accessories for sale so that you can affordably replenish your set.
