Types of commercial door locks 

Commercial door lock types are many depending on the safety provided and pricing. They include cylindrical lever locks, magnetic locks, mortise locks, electronic locks, smart locks, etc. Keypad door locks, biometric door locks, and keyless entry systems are the latest advancements.

Cylindrical lever lock

For the interior doors of your commercial building, this lock is suitable. It has a small cylinder within the locking mechanism. Two handles are provided on either side of the door. This lock can be installed in minutes but provides very little security.

Mortise lock

Mortise locks are popular in commercial applications as they prevent forceful entry. These locks have a strike plate with a deadbolt and this makes it difficult to open them without a key. Mortise locks are best for industrial applications and high-security areas. But they occupy huge space on the door. Only a trained commercial locksmith can fit these locks best.


Deadbolts are used along with other locks. They offer additional protection of security that is hard to breach. Nowadays, deadbolts come with keyless and remote options in automatic door lock systems.

Electronic door locks and smart door locks.

Electronic door locks remove the need for keys and use a code in the form of a PIN to open them. They may also use a magnetic swipe card. If the locks can be operated using a smartphone, they are called smart locks. Keypad and keyless entry systems come under this category.

Grading of commercial door locks.

Commercial locks are graded based on the security they provide as Grade 1, Grade 2, and Grade 3.

Grade 1 and Grade 2 locks are what you must focus on as they provide high security. Grade 1 is for exterior doors while Grade 2 is for office doors for the foyer or lobby area. Grade 3 locks are suitable only for interior doors inside offices and homes. Grade 1 locks are the popular option for storefront doors, garage entry doors, barn doors, main doors of apartment buildings, etc. 

When you think of installing a business door lock system, call a commercial locksmith for consultation. Explore the wide range of commercial door access control systems. Think of both modern features like automatic door opener hardware and traditional features like panic bars for safety. Remember, the security of your office building is the main focus.
