What a Detex Door Alarm Does
A Detex door alarm combines an exit device with an alarm function. It is commonly used on business and building exit doors where staff need an alert when someone uses the door. The exit device must still allow people to leave; the alarm does not replace the door’s basic exit function.
A Detex alarm lock or exit device can be part of a building’s daily security routine. If it is loose, difficult to operate, or making an unexpected sound, the door and alarm hardware may need attention. We provide commercial locksmith service at your property, with the work done on site.

Signs Your Detex Door Alarm Needs Service
The alarm does not sound as expected
If using the door no longer produces the expected alert, the alarm hardware may need inspection. We assess the device and its operation on site.
The alarm sounds unexpectedly
An alarm that activates without normal door use can disrupt staff and building operations. The device and door should be checked to identify what is causing the issue.
The exit device feels loose or sticks
A loose, stiff, or sticking device can make the door harder to use. We inspect the moving hardware and make adjustments or recommend repair or replacement.
The door does not close or latch reliably
A door that will not close and latch as intended may have a hardware or alignment issue. We assess the door and related hardware before deciding what work it needs.
The hardware shows visible damage
Bent, broken, or worn parts can affect the door’s operation. Have the assembly checked so the needed repair or replacement can be identified.
Detex Door Alarm Repair and Installation
- Inspect the door and device — We look at the Detex hardware, the door’s operation, and the reported problem before recommending work.
- Adjust the hardware — When an adjustment can address the issue, we work on the device and door so the hardware operates as intended.
- Repair the assembly — We address repair needs involving the commercial exit hardware and its operation.
- Replace hardware when needed — If repair is not the right solution, we can discuss replacing the affected hardware. The choice depends on what we find at the door.
- Install commercial exit hardware — We provide installation service for commercial panic bars and related door hardware. We assess the opening and the work required on site.
- Coordinate with other door needs — If the building also needs work on door closers or access arrangements, tell us when you call. We also offer panic bars and door closers and master key systems.

Frequently asked questions
Can you service a Detex door alarm at my Gaithersburg business?
Yes. Locksmith Xpress provides mobile commercial hardware service in Gaithersburg and across Montgomery County. We come to your business to assess the door and Detex device on site.
Can you repair a Detex exit device that sticks or will not latch?
We can assess the exit device, door, and related hardware at your property. Based on what we find, we can adjust or repair the hardware, or discuss replacement if needed.
What should I do if my Detex door alarm keeps sounding?
Arrange for the alarm and door hardware to be inspected rather than ignoring repeated alerts. We can assess the device at your Gaithersburg-area business and identify the service it needs.
Can you replace a Detex door alarm at a commercial property in Gaithersburg?
We provide commercial door hardware replacement service. We first assess the existing device and opening on site, then discuss the replacement work indicated by the condition of the hardware.
Will a Detex alarm device prevent people from exiting the building?
An exit device must allow people to leave through the door. The alarm function is separate from the need for the door to operate for exit, and we assess both the device and door during a service visit.
