Types of Garage Door Locks:
Slide Garage Door Lock
Slide door locks are mounted on the inside of the garage door and work just as they look, with the lock aligned with a hole in the track through which a bolt can pass.
Garage Door Handle Locks
Garage door handle locks are extremely uncommon. They’re most generally seen on older garage doors that have to be manually opened. This form of lock necessitates the use of a key to unlock the door. Garage door locks are more likely to need replacement than internal door locks because they are exposed to rain, snow, heat, and other severe weather.
T-Handle Garage Door Locks
T-handle garage door locks, so called because of their design, work similarly like conventional door locks in your home, requiring a key to unlock the handle that must be turned to open the door. The key used in this handle is normally an atypical cylinder shape, and it is mounted on the outside of the lock.
Keyless Coded Garage Door Locks
There are also those who prefer keyless coded garage door locks and those who prefer to lock and unlock their garage doors using a personalized code. These keypads provide versatility, and if a code is broken, a new code can be quickly set up (as opposed to having to rekey or replace a lock if a physical key is misplaced).
