A new lock installation can feel a bit daunting, as there are numerous types of locks. When choosing a lock, you should consider factors like the location of the lock installation, the desired level of security, and the frequency of use. Here are some of the top lock options to research. 

Common Types of Locks

1. Knob Lock

Knob locks are one of the most common types of lock installation. They are typically found on the knobs of inner doors within homes and offices. The knob contains a cylinder, which can be rotated by hand with a thumb turned on the inside. The outside can vary, but some knobs feature a keyhole in which a key is inserted to engage the locking mechanism. 

2. Deadbolt Lock

Deadbolts are most often used on external doors to homes and buildings because they provide strong protection against break-ins. A deadbolt lock relies on a rotating cylinder that moves when a key is turned. The cylinder runs through the door into the frame. 

Deadbolts come in two types: single- and double-cylinder. The former only needs one key on the outside, while the latter requires two keys on both sides to turn. 

3. Electronic Keypad Lock

Electronic keypad locks don't need a key to turn a cylinder. Instead, they function through a numeric pad. When the correct code is entered, a small motor is triggered to move the cylinder. Electric lock installations are most often found in hotels, offices, hospitals, and other places where many people may need to unlock the door. They are becoming more popular for residential use, though one downside is that the lock may not work if the power fails. 

4. Padlock

Padlocks are portable locks that utilize either a key or a combination number dial to unlock a metal U-shaped shackle. They have an almost endless number of uses, such as securing a bicycle, a gate, luggage, a shed door or a school locker. You can find padlocks in all sizes and shapes, though the most typical is a small square for a keyed version or a rectangle for a combination one. They do not provide a high level of security, as they can be compromised by bolt cutters or a drill.
