Commercial Door Hardware in Billings, MT
A door that slams, will not latch, or needs a shoulder to open is a security problem and a liability. We install, repair, and adjust the hardware on commercial doors: panic bars, door closers, storefront locks, and heavy-duty lever sets.

Panic bars and exit devices
Exit doors on a business have to open from the inside with one motion, no key and no knowledge. Panic bars and exit devices do that job, and they take a beating. We install new devices, replace worn ones, and repair the common failures: bars that stick, latches that will not retract, and devices that no longer lock from outside.
We install and service Von Duprin hardware and other commercial exit devices, including rim devices, vertical rod devices, and exit trim with a keyed cylinder for the outside.
Door closers
A door closer controls how the door swings shut. When it wears out, the door slams, drifts open, or stops latching, and a door that does not latch is not locked. Most of the time the fix is an adjustment of the closing and latching speed. When the closer is leaking oil or the arm is bent, we replace it with a unit rated for the door and the traffic.
- Adjust sweep speed, latch speed, and back-check on existing closers
- Replace worn or leaking closers with the correct grade
- Surface-mounted and parallel-arm installations
- Hold-open arms where the door is meant to stay open
Storefront and aluminum door locks
Glass storefront doors in aluminum frames use their own family of hardware: narrow-stile deadlatches, hook-bolt deadlocks, paddles, and pivots. We carry Adams Rite style hardware and repair or replace it on site, including the small parts that fail first, like the latch and the cylinder cam.
Our service call starts at $65 plus parts and labor, and the technician quotes before starting. All work is guaranteed.
- Deadlatch and hook-bolt repair or replacement
- Cylinders keyed into your master system
- Paddle and lever handle replacement
- Commercial lever sets and deadbolts from Schlage and other Grade 1 and Grade 2 lines

What your Billings neighbors are saying
★★★★★I needed to have a lock changed at a property I have listed. I called and they answered right away. They were responsive, available, speedy and very professional. I was very impressed. I have and will continue to refer them to my clients.
Kathleen Candelaria, Billings, MT
★★★★★I can't recommend Independent Lock strongly enough! They have helped me rekey new businesses, installed key pads, got me back into my house (on more than one occasion!), and cut keys on the spot. This locally owned business is one I always trust!
Erica Schuppe, Cody, WY
★★★★★They are awesome! We couldn't get our key out of the door and they came and fixed it for us within a half hour. They also helped us fix another lock that was a security issue. I give them 10/10!

Frequently asked questions
My door will not latch on its own. Can you fix it?
Usually the closer needs adjustment or the strike is out of line. Both are quick fixes on site. If the closer is worn out, we replace it the same visit.
Do you install panic bars?
Yes. We install, replace, and repair panic bars and exit devices, including Von Duprin hardware, with keyed outside trim where you need it.
Can you repair the lock on an aluminum storefront door?
Yes. Storefront doors use narrow-stile hardware such as Adams Rite style deadlatches and hook bolts. We carry the common parts and repair or replace them on site.
How fast can you come out?
During business hours, Monday to Friday 8 to 5, our typical response in Billings is 15 to 30 minutes. Bring us the make of the door hardware if you know it and we will bring the right parts.
What does commercial door hardware work cost?
The service call starts at $65 plus parts and labor. Adjustments are quick; a new closer or exit device costs more because of the hardware. You get a quote before we start.
