Single dial combination locks are mostly used in school lockers, padlocks and safes, while the multiple dial combination locks can be found in luggages, bikes and briefcases.

Electronic locks are similar to single dial locks in terms of design, however, the mode of entering the sequence is quite different. In the latter, a keypad is used instead of a dial.

In safe locks, you have to turn a dial to enter the combination code before the safe door can be opened.

3. Biometric Locks

Since it only requires a picture of your finger for verification, anyone can easily manipulate the system with a picture of your fingerprint.

Herein, the most reliable scanning technology is the ultrasound scanner which uses sound waves to read the inner layer of your fingerprints.

4. Cylindrical Locks

Unlike a mortise lock which requires a pocket cut to be made in the edges of a door, a cylindrical lock requires a hole to be through the whole door. This is what basically distinguishes the cylindrical lock from its counterparts.
Each end of the cylindrical lock has a knob or lever whose function is to retract the latch on the door lock whenever it’s turned.

Most of the time, cylindrical locks are installed by boring two holes through the door; a larger one from the face or front of the door and a smaller one from the side of the door.

A metal bar goes into the small hole whenever a key is used on the lock. The lock can be opened by turning the knob. In the case of a lever head, you will be required to press it.

In other words, the locking mechanism is two fold. The entire installation process is known as the “boring” method.

5. Knob Locks

Knob locks are the most commonly used door lock in residential settings. Sometimes they might be installed to complement deadbolts on exterior doors.

This type of lock basically has its cylinder in its knob instead of the door. The key cylinder is located on one side of the lock while the knob is found on the other that’s in charge of the locking mechanism.

This is why it is not recommended to use them as the chief method of security for external doors, as its very easy to get behind such doors with basic tools like pliers, screwdriver, wrench or hammer.

So except you are exclusively using them for your interior doors between rooms, it’s always a good idea to use them together with a secondary lock to help them resist brute force attacks. A good example of a secondary lock you can use for this purpose is a deadbolt.

Besides forced break in, knob locks are also prone to shimming and picking.

6. Cam Locks

A cam lock is mostly used in fully constructed cabinets and often hidden away from sight in other not to affect the outward appearance. Just like any other lock or fastener, they are used to secure items, especially sensitive materials.

Cam locks are often cylindrical and are inserted into the cabinet wood or any other furniture wood. They are usually cheap and come with cylindrical base that consists of keyhole and a metal tube known as the cam.

Most cam locks are usually positioned at joints for improved security. And usually require a key for them to be opened.

7. Deadbolt Locks

If you’re looking a budget-friendly way to secure all your external doors, then the deadbolt lock can be a great option.

This type of lock comes with a keyhole on the outside which pushes a bolt in the lock cylinder sideways when turned with a key. The door gets locked as the cylinder causes the bolt to thrust forward into its frame.

The strike plate in the door frame helps to secure the door against forced entry to keeping the bolt in position and ensuring it doesn’t rip through the frame when subjected to a lot of pressure, such as in the case of a burglar trying to force his way through.

This is what makes deadbolt locks reliable for exterior doors. As we indicated earlier, they can be used in addition to knob locks.
