A deadlatch is a locking mechanism that locks automatically without having to turn a knob or use a key. It rests against a metal strike plate mounted on a door frame. The deadlatch works by using a bolt to block the door from opening, giving your door extra security.
Definition of deadlatch
: a spring-bolt latch in which the bolt is deadlocked against end pressure but may be retracted by either the knob or the key.
A deadlatch is not spring-loaded, and provides extra security over a spring latch. A latch is operated with a key on the outside and a turn-style knob on the inside. One great feature of a latch is that it can be set to automatically lock when the door closes. This extra safety feature is helpful in any home.
In the United States, there are two common backsets for residential door locks: 2 3/8 inches and 2 3/4 inches. Pack your locks with a 2-3/8-inch or 2-3/4-inch latch, depending on which backset you specify. Dummy sets have no latch and are surface-mounted so you can install a dummy set wherever you choose on the door.
Strike Plate
This is the plate the latch-tongue, or deadbolt-tongue will connect with. It should sit flush with the door jamb. Any passage or privacy set needs to have a strike plate for the door to latch. Additionally, deadbolts need a strike plate to properly lock.
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 rim automatic deadlatch with key-locking handle is a door latch that's locked and unlocked with a handle from the inside and a key from the outside. It's often used as an additional security measure rather than the main lock.
The guardbolt is designed to move in unison with the latchbolt up until the point where the latchbolt extends into the strike plate. At that point, the guardbolt remains in a depressed position against the strike plate, preventing the common burglary practice of “jimmying” or “shimming” the latchbolt.
Deadlocks vs sashlocks
A deadlock is a lock that is permanently shut once you've locked it, until you unlock it. It doesn't latch shut, nor does it open without a key (unless there is a thumbturn cylinder on the inside). A sashlock is all of the above things, plus there's a latch and a pair of handles.
Do Deadbolts Go Above Or Below The Door Handle? Deadbolts are often put above a door handle, although they can be positioned both on top or under the doorknob. Placing a deadbolt on top of the knob is more likely to prevent clashing and makes the lock easier to access.
Deadlocks require either a key to lock the door or to turn a knob into lock mode, but Deadlatches lock automatically behind you after closing it. This adds a level of convenience and peace of mind, knowing that the door is locked after you closed it.
Lock Grades and Ratings
Deadbolts provide the highest level of front door security. To ensure your door locks provide solid home security, choose locks and deadbolts that are pick-resistant and bump proof.
In the U.S., there is no single comprehensive law against dual-cylinder deadbolts. Individual cities and states have local property and fire codes that may prohibit the use of dual-cylinder deadbolts. The code may prohibit the use of dual-cylinder deadbolts in some buildings and allow them in others.
One way to check your front or back door locks are conforming to BS3621 is to look for the British Standard Kitemark (BSI) on the faceplate of the lock. The faceplate of the lock is viewable when you open the door; you should also see the specific standard number e.g. BS3621 stamped on the plate.

Tape a coin over the door's strike plate.
Use thick tape, like masking tape or duct tape. You may want to place the coin over the door's latch. This can hold the door handle at an open angle, allowing you to push the door open and closed without turning the knob. This will also prevent the door from locking.
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.

Still, having longer screws isn't a guarantee that no one will be able to kick in your door. It might just take a bit longer for it to come apart. “Those longer screws go into the stud that's behind a door jamb, so instead of splitting that initial wood, it's in a deeper sub wood, so it's grabbing more,” Whipple said.
