One of the best-known ways to unlock a deadbolt without a key is by using two bobby pins. Start by inserting the closed "looped" side of one bobby pin into the bottom portion of the lock. Use the second bobby pin, broken in half, toward the top of the lock and move it back and forth.
A screwdriver is the most convenient option to unlock a deadlock. This tool is strong enough to rotate the internal lock clip easily. However, users should follow some processes while using this tool for unlocking deadlock.
To loid the lock with a screwdriver, push the tip of your screwdriver between the door and the doorknob until you feel the spring latch. Continue pushing to retract the bolt until the door pushes open.
Start by pulling the bobby pin apart and roughly straightening it as such. Next, stick the straight end of the hairpin about one centimeter, or about 1/3 of an inch, into the keyhole of your lock and apply enough pressure to bend the end of the pin into a hook. The result should look something similar to this.
Take your knife, and at the exact height of the doorknob, insert it between the crack of the door and the doorframe. Probe around until you feel a hunk of metal extruding out of the door—this is the latch, and it should feel springy! Leverage your knife and push the latch into the door.
Generally speaking, deadbolts are sturdy locks that can withstand kick in and other forced entry attempts. However, a door with a deadbolt can still be kicked down if the door itself is not solid. So, to protect your door against kick in, you want to make sure both the lock and door are of high-quality grade.
Picking a Locked Bathroom or Bedroom Door Lock
Most interior locksets have a pinhole on the outside knob for emergencies. All you need to pick one of these locks is a single straightened-out paper clip to substitute for the pinhole door knob key. Insert the paper clip into the pinhole and push on it to unlock the door.
Ideal choices include a small screwdriver or hex wrench, a hair pin, or a heavy-duty paperclip. You can even use a bamboo skewer from the kitchen, or a cotton swab with the fluff removed from one end. If using a hair pin or paper clip, first bend it open so you have a long, straight bit of metal.
A minimum of 10, 75-pound strikes are reported to be the equivalent of over 100 foot pounds, which is why the Grade 1 deadbolt locks have been tested. A really strong criminal would have to kick your door over 100 times in order for it to begin to degrade or show signs of weakness.
The best way to reinforce your frame is by adding a layer of steel to prevent them from splitting. This makes your door kick proof. Installation entails placing high-gauge steel over the door jamb and securing it with long screws. The screws should penetrate through to the wall studs on all sides of the doorway.
The BHMA/ANSI has three, separate grades for deadbolts, simply labeled grades 1 through 3. Grade 1 is the highest quality, and the most dependable deadbolt you can have. Grade 3 is your average deadbolt which will provide an accepted, but minimal, level of security.
If the door or frame are made of wood or a hollow-core material, you should be able to kick it down with minimal force. Exterior doors are usually made of solid-core material, such as chipped or shaved wood and laminate, and are harder to kick down.
If you're locked on the other side, look for a tiny hole on the doorknob. Push an eyeglasses screwdriver, a paper clip hammered flat, or a very small butter knife into this hole. Push it straight through as far as you can, and turn or twist it until it catches a groove and the lock clicks open. Pick the lock.
The most common are paper clips, bobby pins and electrical wire, but in a pinch, implements such as tooth-flossing handles can also work. Bobby pins probably work the best. If the weather is cold, you might also need a means to de-ice the lock because you won't be able to turn it if it's frozen.
