2. Types of Digital Door Lock

Digital door lock can be given the meaning of different ways depending on what it is they are meant to open, how they are wired to your home and how they work.

Every digital door lock can be opened and closed without a key, but a few types can be opened and closed either way. These locks consist of a keypad and a standard key or a smart key card. One of them will open the door. These locks are suitable for:

  • Multiple users

  • Users who usually lose their keys

  • Users who usually go away from home and need a neighbor to check in; the neighbor can be provided a unique password, rather than a key. The new password can be set once the owner comes back home.

Limits of this type of door lock include:

  • Bump keys are able to open this type of lock

  • They are usually spring-locks, not deadbolts, making them easier to open

  • Single-Sided Deadbolt

Single-sided deadbolts are one of the most popular product lines of deadbolt fitted on most homes. They work under the cooperation with a second lock fitted on the doorknob itself. One side of the deadbolt can be moved following its direction without having a key or combination; the other side is in need of a password to unlock. People can install digital deadbolts in place of any existing deadbolt.

  • Double-Sided Deadbolt

For door having glass panes or panels, double-sided deadbolts is very important. Two sides of the deadbolt need a password to open; if the glass of doors was ever broken, the deadbolt could not be flipped by someone accessing in.

  • Battery Operated Digital Door Lock

Door locks have many different ways to operate. One of the most popular ways is to be supplied with power by a battery. Battery operated door locks often have an LCD display, emit lights out when touched and are easy to program again using a master code. The limits of a battery lock, however, is that the batteries always need to be replaced every year; if the battery runs out, the keypad function will not operate. Most locks do have a low-battery light warning to help point out when this case will happens.

People usually mainly use battery-operated door locks for door knobs and interior locks; they do not commonly use them for deadbolts. Many battery-operated locks also have a back-up key; if the battery runs out, the key is the temporary solution.

  • Mechanical digital door lock

Mechanical digital door lock doesn't need a battery or on electricity / energy to operate. Instead, they depend on tumblers like a standard key; press codes / numbers / passwords on the keypads, adjust the tumblers and unlock the door. Mechanical digital door lock is bump proof, kick proof and never wear out even with frequent use. Unluckily, the number of digits in a password, as well as the number of passwords you can use with this type of lock is more limited.

People primarily use this type of digital door lock for deadbolts, exterior locks and high-traffic areas that have a high demand of closing and opening.

  • Alarm Locks

Alarm locks will emit a loud signal if you press the wrong passwords too many times or try to break the lock. They may be linked to your home's warning system, or they can have their own warning system that operates only with the lock. They are almost always lined right into your home's electrical system, so they do not need any battery. If there is no back-up key, a loss of power may stop all their operations.
