  • Types of locks

The core concepts are broken down into more digestible portions in each segment. I hope you read it all, but if you don’t have time (due to your busy schedule), simply contact a local commercial locksmith. An expert who has assimilated this knowledge and can assess your specific circumstance is beneficial.

Considerations When Replacing a Commercial Door Lock

Several variables must be considered in order for your commercial door lock replacement to be successful. You’re more likely to waste money on items you can’t use, shouldn’t use, or don’t give you what you need if you don’t account for these considerations. However, avoid tunnel vision and concentrating just on your locks.


Commercial door lock replacement isn’t always the sole choice when it comes to changing locks. Rekeying your current locks is a less expensive and less intrusive solution. The primary distinction between rekeying and replacing locks is that rekeying keeps all of your old hardware, including the lock cylinder. Rekeying a lock only affects which keys will operate in the lock, but it can also include security pins to improve the lock’s security. If the lock hardware or cylinder is broken, this is not a suitable option for commercial door lock replacement.

When a key is lost, stolen, or otherwise compromised, rekeying is the best solution. In these cases, it’s time to alter the locks in such a way that all currently working keys are rendered useless. However, you do not have to replace all of the business door locks. Simply alter what makes a specific keyword. Stakes of pins of varying heights match the grooves on your keys in a simple commercial door lock. You can alter the height of the pins to modify the key that opens the lock.

When you replace the pins, the lock is sufficiently altered that only a new key will work. Rekeying is a wonderful way to make several commercial locks function with the same key, reducing the number of keys each employee has to carry. If the locks you want to key alike all have different cylinders, they won’t be keyed alike because the keys will be different sizes, shapes, etc. You may need a business door lock replacement to rekey many locks to work with the same key.

Size & Fit

If you want to preserve your old door or just replace a lock cylinder without replacing the entire lock hardware, you’ll need to pay strict attention to all of the measurements. Your new locks must be compatible with anything you plan to install them in. Fortunately, most new businesses and storefronts use conventional door sizes and are cut to accommodate standard commercial locks. Commercial door lock replacement, on the other hand, cannot be so straightforward. Extenuating conditions might make what should be a simple procedure more difficult.


The major purpose for installing a lock on a door is security. When it comes to commercial door lock replacement, make sure to think about how your lock protects you. You’re attempting to limit access to all unauthorized individuals while also preventing criminals from committing theft or vandalism. Despite the fact that any lock can be picked, most thieves do not do so. They’re more prone to employ bump keys or bypass methods, and they almost always use brute force or destructive entry. As a result, you’ll require locks that are designed to bolster your protection against these more likely threats.

Key Control

Aside from the physical architecture of the lock, key control can also improve security. This is particularly critical in the case of shop security, as anyone with a key has access to your merchandise. As a result, only authorized employees should have access to keys. Certain high-security locks use proprietary key technology, which makes illegal copies extremely difficult. A do not duplicate stamp or etching will not prevent someone from duplicating a key at a self-serve key machine, which may be found at any hardware shop.

Commercial Door Lock Replacement Types

Because there are so many different types of commercial door locks, the specifics of commercial door lock replacement will vary. It’s critical to extrapolate the information in each part and apply what’s relevant to your scenario while ignoring what isn’t. Contact a Locksmith Service for assistance recognizing your lock, although the most prevalent types of business door locks fall into the following categories:

  • Basic Locks
  • Push Bars
  • Electronic Locks

Basic Locks

Adams-Rite locks are the most frequent locks used on storefront door hardware (aka. aluminum storefront door locks, glass storefront door locks). This implies you’ll be dealing with mortise locks for the normal commercial door lock replacement. The mortise lock gets its name from the space (or mortise) carved into the door into which the lock goes. Your new lock must fit into the same pocket as the old one, or the new cylinder must be secured to the door/hardware.

Push Bars

Push bars (sometimes known as panic bars or exit bars) are used for safety or convenience rather than security. Push bars, on the other hand, can provide commercial-grade security on the side of ingress, unlike bathroom door locks, which are designed to just suggest a denial of access.

Electronic Locks

Electronic locks are now used in many business buildings. If your electronic locks are hardwired, as they often are in business areas, they should not be replaced without professional assistance. The only electronic locks you should try to install yourself are those that are powered by batteries. Battery-operated electronic locks are designed for home use and are easier to remove and replace than mechanical locks. You can get an overview of the process by consulting the paperwork that comes with them.
