Keyless locks are locks that one would be able to unlock or lock without the use of a key. Keyless locks are locks such as a combination lock, or other types such as a keyless home security center where you can use a remote to lock doors. Generally with a keyless lock you will be required to enter a combination to release the lock.

There are simple combination locks with just a number pad, however they can be more advanced with some including letters and other symbols making the combination more secure.

Other forms of keyless locks include biometric scanner locks (such as fingerprints) and password deadbolt type locks. The password locks are similar to a combination lock but tend to hold a larger number of possible combinations than the standard locks and the biometric scanners increase the security greatly. Although these locks are much more rare, they are increasing in popularity with home owners and business owners a like. Many have no physical lock front, this means that an intruders are unable to pick the lock the conventional way, making them even more secure. Another bonus to these locks is that you will never lose your key.

These scanners tend to be mostly fingerprint scanners as they are the more common and affordable finds on the market. While not exactly the cheapest type of lock system they do provide a fairly easy way to get into your home while preventing and deterring intruders. These scanners prevent the need of a key or a password for even easier use. The only thing you require is your fingerprint and it will unlock the door. The simplicity of use can outweigh the cost in terms of protection and security that these types of electronic locks can bring.

On the down side, biometric scanners are rather difficult to install. They normally require a professional installation which can add up in cost. Although varying in install complexion it is a task that most average home owners are not suited for.
