The keypad door lock was previously seen mostly in commercial settings. The numerical, electronic keypad resembles the layout of an ATM or adding machine. A code rather than a key opens the door.

Offices and warehouses often had keypad door locks. It saves the expense of frequent key and lock changes, especially with frequent employee turnover, as well as adding an element of security.

Residential Use

The keypad door lock is becoming more popular for residential applications. They are an excellent choice in several residential situations.

For example, if you have younger family members who are old enough to enter the home alone, but are not completely responsible for keeping track of keys, the electronic keypad is an excellent choice. This also applies for those who tend to lose keys frequently.

A keypad also eliminates the need to leave a key hiding outside the home for a serviceman or occasional guest. This is never a safe idea since burglars tend to look quickly in the obvious key-hiding places.

Cost and Availability

In previous years, finding a keypad door lock meant visiting a specialty, commercial locksmith. However, the average homeowner can now find these locks at home improvement centers.

The cost for the locks varies according to the features you want. However, the range goes from $130 to about $400 for home applications. Commercial locks can be over $1,000, but these expensive locks have features not needed by the average homeowner.

The door locks are excellent for security. You can buy models that accept up to six or eight different codes, meaning that each person in a family or organization can have a different code.

If you have household help that enters the home while you are away, you can give them their own individual codes and see exactly when they entered the home.

When a person moves out or no longer works for you, you can change their individual code without altering the codes for the other members of the household. This adds convenience and security to the family.


Keypad door locks have a variety of features, depending on the model you purchase. Many of the keypad door locks install in the place of a standard door handle, requiring little to no alteration of the standard openings in the door – no drilling, cutting or filing, in many cases.

There are some other features you may want on a keypad door lock. One is a key bypass. If you forget the code, have a person who needs temporary access and you don’t want to give them a code, or encounter any other situation where a key is useful, then the key bypass model is a great idea.

There are also models which feature remote controls. These use either a keypad or a remote control to unlock the door, adding flexibility and control.

Many of the styles of lock come in a variety of decorative finishes, including the bright brass, rubbed brass, chrome, brushed nickel, and other finishes you might want in your home hardware.
