These locks constitute an upgrade over the more conventional deadbolt lock that require keys. Instead of keys, these locks utilize electronic keycodes to allow access and egress. They may be especially useful for those who tend to lose their keys.
Electronic Deadbolt Lock Design
These locks, like other deadbolt locks, feature an assembly that is usually mortised into a door with a thick metal strip, called a bolt. Experts recommend that the bolt measure at least inch long. A companion part for the lock, called a keeper plate is mortised into the door jamb. Batteries provide power for the locks' operation. Most models give an indication when battery power is low and need replacement.
These types of locks are available in both single or dual-cylinder models. Single-cylinder models require key insertions on a door's outside, while dual-cylinder locks require key insertions on both sides. Experts recommend the dual-cylinder model as a potential burglar may break glass in a door, reach through the resulting hole and turn the lock's knob to gain entry.
Most models allow the user to change the code frequently and can store multiple keyfob codes. Some also feature an automatic locking feature that many find useful. For example, many children, teenagers, and elderly may be absent-minded and neglect to lock a door after exiting through it. The automatic feature addresses this type of situation.
Installation of Electronic Deadbolt Locks
Experts recommend hiring professionals to install deadbolt locks for the first time they are mortised into a door because of the precision required to bore holes in the door at exactly the points where they are needed. However, if you are replacing a conventional deadbolt, then installation of the electronic variety can be quite simple.
Usage of Electronic Deadbolt Locks
For a conventional lock, the user turns a screw or lever and the locking gear inserts the bolt into the keeper plate or removes it to unlock the door. Electronic deadbolt locks use the same principle except that the user punches a code on a keypad and then the locks mechanism inserts or removes the metal strip. Many of these locks also feature illumination to facilitate the user inputting the keycode in dark surroundings.
Some models also allow users to open or close the lock with a keyfob signal and thus increase the measure of convenience for an individual.. This allows the user to combine the lock with other systems operated by remote control such as a garage door or outside lights.
