Commercial lock repair

Most commercial lock faults fall into a short list, and most can be fixed without replacing the whole lock.

Storefront door locks

Glass and aluminum storefront doors use a narrow deadlock with a swinging hook or bolt. Typical faults are a key that spins without throwing the bolt, a loose cylinder or a bolt that no longer reaches the frame because the door has dropped.

Mortise locks

Common in older DC office buildings. Springs, latches and cylinders wear out long before the lock body does. We rebuild them and keep the original hardware where it makes sense.

Commercial levers and knobs

Sagging levers, handles that spin freely and latches that stick are usually worn internal parts or loose mounting, both repairable.

Exit devices that will not latch or release

A panic bar that does not latch leaves the door unsecured. One that does not release is a safety problem. We adjust and repair the latch, dogging and strike.

Keypad and electronic locks

We replace failed keypads, fix locks straining against a misaligned door and reset units after a lost code.

Commercial lock installation

New hardware has to suit the door, the traffic and the way the space is used. We install:

Commercial-grade lever locks with the right function for each room: entrance, office, storeroom, classroom or privacy.
Mortise locks and cylinders for heavy-use doors.
Storefront deadlocks, latches and cylinders for aluminum-framed glass doors.
Deadbolts and auxiliary locks for back doors and stock rooms.
Keypad and electronic locks for staff entrances.
Exit devices and door closers where the door needs them.

New locks can be keyed into your existing key system, so staff are not handed another key.

Choosing the right grade and function

Two things separate commercial hardware from what goes on a house.

Grade. Commercial locks are rated for how many cycles they survive. A front entrance needs the heaviest grade. A rarely used closet does not.

Function. The same-looking lever can behave differently: always locked from outside, locked only by key, or lockable from inside by a button. Picking the wrong one is the most common reason offices end up with doors propped open or people locked out. We go through each door with you.

Doors on an exit route have to let people out without a key. We will point out where that affects the choice.

Repair or replace?

We repair when the lock body is sound and parts are available. That is usually the case with good commercial hardware, which is built to be serviced.

We recommend replacing when the lock was forced, parts are discontinued, the lock is a residential grade on a busy door, or it has already been repaired more than once.

If the door itself is sagging or the frame is damaged, the lock will keep failing until that is fixed. We will show you if that is the real cause.

What it costs

Commercial locksmith service starts at $125. Simple adjustments and cylinder repairs sit at the low end. Mortise rebuilds, exit devices and new hardware cost more, depending on the parts.

You get a price before work starts. See our price list for other starting prices.

Commercial lock FAQs

My storefront key turns but the door does not lock. What is wrong?

Usually the cylinder has worked loose or the cam behind it has slipped, so the key no longer drives the bolt. It is a common fault and normally a quick repair.

Can you match new locks to our existing keys?

In most cases, yes, if the new hardware accepts the same keyway. We check your current key before ordering.

Can you come before we open or after we close?

Yes, within our hours of 6:30 a.m. to 11:30 p.m. Early and late appointments are common for shops and restaurants.

How long does a commercial lock repair take?

Many repairs take under an hour. Mortise rebuilds and exit devices can take longer, and special-order parts may need a second visit.

Do you work on panic bars and door closers?

Yes. We repair, adjust and replace exit devices and closers as part of commercial lock work.

Should we switch to keypad locks?

They work well on staff entrances with regular turnover. For several doors or a need for entry records, see access control systems.
