About Simplex locks
Simplex locks are mechanical push-button locks that allow keyless entry using a numeric code. They are designed for durability and do not require electricity, making them a dependable option for properties that want consistent access control without relying on batteries or wiring.
These locks are commonly installed on office doors, storage rooms, employee entrances, and restricted areas. Their simple design makes them easy to use while still providing controlled access.
Simplex lock change services
Simplex lock change service is recommended when the lock is worn, damaged, or no longer functioning correctly. Replacing the lock ensures reliable operation and allows you to upgrade to a newer or more suitable model.
We replace Simplex lock bodies, lever sets, and internal components depending on the condition of the hardware. For doors that require additional security, we may also recommend installing a compatible deadbolt or coordinating with a full lock replacement for other entry points.
If your door does not currently support a keypad lock, we can also perform fresh lock installation to create a proper setup for a Simplex system.
Code change and access updates
One of the main advantages of Simplex locks is the ability to change access codes without replacing the hardware. Updating the code is an effective way to maintain security when access needs to change.
Code changes are commonly requested after employee turnover, tenant changes, or when the existing code has been shared too widely. We can reset the code, configure a new combination, and ensure the lock operates correctly after the update.
Regular code changes help maintain control over access and reduce the risk of unauthorized entry.
Simplex rekey services
Some Simplex locks include a keyed cylinder for additional access control. In these cases, rekeying can be performed to change the key without replacing the entire lock.
Rekeying is useful when keys are lost or when access needs to be updated. It can also be combined with other services such as lock rekey for additional doors or lock repair if the lock requires adjustment.
If the lock does not include a keyed cylinder, access control is managed entirely through code changes rather than traditional rekeying.
Common applications
Simplex locks are commonly used in commercial and institutional settings where controlled access is needed without the complexity of electronic systems. These include offices, schools, storage areas, and employee entrances.
They are also used in environments where reliability is critical, since they do not depend on batteries or wiring. In some cases, Simplex locks are paired with other hardware such as mortise locks to meet specific door requirements.
When to service or replace
Customers usually request Simplex lock service when the keypad becomes difficult to use, the lock does not engage properly, or the code mechanism becomes unreliable. These issues can often be resolved with adjustment or repair, but replacement may be necessary for heavily worn units.
Code updates are recommended whenever access needs change. Replacement is recommended when the lock no longer operates smoothly or consistently.
