How Does A Biometric Door Lock Work?

A biometric door lock combines an electric lock with a fingerprint scanner to open or lock doors in homes or businesses. A biometric scanner can sometimes require a fingerprint or thumbprint scanner and a combination of keys, facial recognition, and maybe even a physical key to open.

It all depends on the model of biometric door lock you use and your configuration.

However, you can further increase the effectiveness of biometric door locks at home by adding a deadbolt to the door and using locks that require a key or combination keypad for stronger security.

How to install biometric door locks

Biometric door locks are effortless to install. You don’t even need the help of a professional as you can do it yourself. All you need is a Philip screwdriver to loosen and tighten screws.

You don’t need to drill any holes to install these biometric door locks.

9 Things to look for when buying a biometric door lock

  1. Power source
  2. Multiple fingerprints
  3. Mechanical key option
  4. Low Battery Indicator
  5. Built-in alarm
  6. LCD screen
  7. Live Finger Detection option
  8. False Rejection Rate (FRR)
  9. Lock material

Are you looking for a cheap biometric door lock? It would be helpful to consider these important factors because they will help you make your decision better. It would help if you looked out for the important things when looking for the cheapest biometric door lock online.

1. Power source

This is very important. Some of these systems are tied to house power and only house power. This can obviously be a problem if the power goes out and you have no mechanical way to open the door.

Others are pure battery operated, which is less of a disaster, but means you have to keep them charged at all times. If you can get a combination of both, that’s good peace of mind.

2. Multiple fingerprints

You really don’t want a lock that can only identify one fingerprint profile or finger. Even if you live alone, allowing other people (family, friends) access is critical.

3. Mechanical key option

You still want to have a way to open the lock with a mechanical key in most cases. If the battery is low or the lock is connected to the power grid in the house and the power goes out, you still want to enter without any problems.

The choice of these locks is complicated, and although their presence somewhat reduces the effectiveness of biometrics, sometimes compromises must be made.

4. Low Battery Indicator

If you have an isolated power source for your lock (a good idea), you want a warning when the battery is running low. You don’t want to know when you can no longer easily get into your home.

5. Built-in alarm

An alarm system that beeps when the door is opened can also be helpful. If someone somehow manages to pry it open, the alarm will likely deter them. It also means that no one will be stalking you when you get home!

6. LCD screen

An LCD screen that shows the time, access attempts, and perhaps reasons for denial of access is also handy. A stoic piece of metal with no display other than beeps and flashing lights is remarkably unhelpful under any circumstances.

7. Live Finger Detection option

Live finger detection can determine if it is a real finger still attached to a live body.

8. False Rejection Rate (FRR)

Technology can never be perfect, and you should look for a biometric device that rejects a small percentage of valid users. That’s something I wish the biometric panels I’ve worked on had.

9. Lock material

If possible, choose strong materials like titanium or steel, as they are harder to pierce or break by impact.
