How to unlock door without keyhole. The most commonly used technique globally is using a credit card to open a locked door that doesn’t have a keyhole. Insert a card made of hard plastic material into the gap created right above the doorknob. Apply great force on the door, using your hand, legs, and part of your body, if you would.

For this method, you will need a small drill, a flathead screwdriver, and lubricant. It is mainly preferred on privacy locks, whereby one targets the latch. Follow the steps below to unlock your door through its pinhole:
