Combination Locks

As the most known method for locking solutions, the combination lock is also one of the most versatile. Combination locks require a specific sequence of numbers (or letters) for opening. However, because of the versatility, this type of lock may come as a single or multiple dial, electronic keypad, or a combination of dial and key. Often used for school lockers, bikes, and safes, the combination lock is generally the most cost-effective solution depending on the job.

While just as popular, deadbolts serve an entirely different purpose. Deadbolts are one of the most cost-efficient and effective ways to secure an external facing door. Revolving around a cylinder, the key turns not only the lock by the bolt inside of the mechanism. For extra security, the double bolt option requires a key for unlocking from both sides of the door. However, it’s crucial to note that the double bolt can also pose a danger in the event of an emergency, like escaping a fire.

Biometric Locks

For those looking for one of the highest, most technical levels of locking security, let us introduce you to the biometric lock. Often associated with movies, the biometric lock utilizes a fingerprint to unlock. In many cases, both a fingerprint and a PIN are set to ensure the highest security level.

Biometric locks can be used for various scenarios ranging from door opening to safe entry. This type of lock offers some of the most excellent security and some of the highest convenience levels. However, without the need for a key, one is relying upon electricity or batteries. So, staying on top of maintenance is critical for seamless operation.
