5 Types of Door Locks 5 Types of Door Locks

Being that doors are such an important part of our civilization, it only makes sense that there are a number of different types of door locks to secure them. From door knob locks to deadbolts to keyless locks, there is a type of lock to suit every door and every security need. It will only take you a few moments to learn what types of locks are on the market today. Maybe you are interested in updating your locking system, or perhaps you are just curious about the technology available. Either way, this article presents an informative look at several door locking options to choose the best one for your door.

Door Handle Locks

This type of lock is the least secure. It is simply a lock that is contained within the handle of a door—either a push-in button or a turning mechanism. It works by preventing the handle from rotating. Because it is so easy to break, this type of lock is usually used on bathroom doors and other inside entryways. Another lock of this kind consists of a button that is found immediately next to the door handle, and it works in the same way. You can find this on front and back doors, but it is not operated the same; it is operated with a key.

Deadbolts

The old standby for front and back doors, deadbolts provide security through the use of a solid metal cylinder that protrudes through the door jam and into the wall to completely secure the door. Deadbolts are often found in use with door handle locks to add a second level of protection. Because deadbolts require a key to lock them from the outside, they are still theoretically vulnerable to picking and bumping. Nevertheless, for most residential homes, deadbolts provide more than enough security for doors leading to outside.

Keyless Locks

Keyless locks work just like the name implies. Using no key for entry, the door is locked and unlocked using a code that is entered into a keypad. This adds yet another level of security. Keyless locks typically employ a deadbolt, but there is no keyhole, so there is no danger of picking the lock. Keyless locks are often found in commercial buildings and other places where heightened security is a necessity.

Electric Locks

Electric lock devices work like any lock, only they are not manually applied. The mechanism that locks and unlocks the door is run through electronics, but they can be opened with either a key or through a code on a keypad. The beauty of electric locks is that they cannot be overridden by manual lock picking tools or brute force. They are wired electronically; therefore any forced entry will require a rewiring of the system. This task is beyond the scope of all but the most sophisticated lock pickers, and even they will have a tough job to do.

Combination Locks

A combination lock is much like a keyless entry, only the keypad functions through a push button mechanism. Rather than a digital or electronic coding device, the keypad on combination locks triggers the movement of a deadbolt mechanically.
