You can purchase a digital deadbolt lock in any of three styles—pushbutton combination locks, remote electronic signal locks, or biometric fingerprint-coded locks. All of these work effectively with other home security system components to provide complete protection for your home and family. Read on to learn about how a digital deadbolt lock works.

Digital Deadbolt Lock Parts

A digital deadbolt lock is made up of an external keypad or pressure sensor. This may operate on batteries or another electricity source, or it may be purely mechanical. A standard format deadbolt lock is fitted into the door itself and into the door frame. On the inner face of the door is a lever or turn handle that releases the deadbolt from inside the house.

How These Components Work Together

A digital deadbolt lock with a mechanical keypad works as follows. Set a combination from 10,000 or more possible choices and key it into the keypad. When you are outside with the door locked, pressing the number combination will lift a series of tumblers to release the deadbolt lock. The combination also serves to engage the deadbolt when you leave the house.

You can set an electronic keypad digital lock in the same way that you set a mechanical digital lock. The electronic keypad offers added security features such as an alarm that will sound after four incorrect tries of the numerical password. Distinct audio tones also signal you when the door unlocks successfully, when the batteries are low and when the door lock is jammed.

Biometric Locks

These digital locks are keyed to your fingerprint and those of a few family members. The pressure sensor reads the correct fingerprint and sends an electronic signal to the door lock to release. When the door is locked, a corresponding signal from the fingerprint will unlatch the lock.

Remote Access Locks

These locks are very helpful for people with disabilities who need to maneuver a wheelchair or other mobility assist device through the doorway. The door can be disengaged and ready to swing open when they reach it. You can choose either a radio-frequency or an infrared remote device, both of which can protect against tampering. The lock is programmable with one push button. The remote device will emit different audio tones that signify lock, unlock, low batteries, and a jammed lock. Since some of these locks still can be engaged and unlocked with a key, the possibility of tampering still exists through lock bumping.

Other Uses for Digital Deadbolt Locks

This type of lock can be fitted to create a security door for a medicine cabinet, a gun chest, or even your home office. It will keep medications, valuables, dangerous items, and personal papers. Digital locks can protect your family inside the home as well as keeping intruders out of your property.

When you want to upgrade your home security, installing digital deadbolt locks on all the main entries into your home will deter even the most persistent intruders.
