Why storefront locks are different
Aluminum storefront doors have a narrow frame (stile) around the glass, so they can’t take an ordinary residential deadbolt or knob. Instead they use compact locks built to fit inside that stile, operated by a mortise cylinder from outside and a thumbturn, paddle, or second cylinder from inside.
Because the parts are specialized and the aluminum is soft, a “close enough” replacement often leads to a cylinder that won’t turn or a bolt that won’t throw. We measure before we order or install; storefront lock parts are ordered for your door, not stocked.
Hookbolt deadlocks
Narrow-stile hookbolt deadlocks throw a curved hook bolt into the frame or the other door. They’re common on the main entry of retail and office storefronts and on pairs of doors without a center post.
Deadlatches
Narrow-stile deadlatches latch automatically and are opened with a paddle, push or lever, so the door can operate during business hours and still latch when it closes.
Mortise cylinders
The keyed cylinder screws into the lock body and uses a specific cam. A wrong cam is a common reason a new cylinder “almost” works. We match cylinders to your existing key system when needed.
Storefront problems we fix
The key turns but the bolt doesn’t throw. The bolt throws but won’t go into the frame. The deadlatch won’t catch, so the door drifts open. The paddle or push handle is broken. The cylinder spins loosely in the door. The lock was pried or damaged in a break-in.
Misalignment is a frequent culprit. Storefront doors sag over time on their pivots or hinges, and the bolt starts hitting the edge of the strike instead of the hole. Adjusting the door or strike can save the lock entirely.
Measuring matters: backset and cylinder
Narrow-stile locks come in several backsets, the distance from the door edge to the center of the cylinder. Older and newer storefront doors may use different backsets, and installing the wrong one leaves the cylinder misaligned with the hole in the door.
Cylinder length depends on door thickness and any trim rings. We check both, along with the cam type, so the replacement fits the door you have rather than the one in a catalog.
- Order or call. Use the order page and text or email us a photo of the lock face on the door edge if you can.
- Approve the price. You review the price and deposit before submitting.
- Diagnose on site. We check the cylinder, lock body, strike and door alignment.
- Repair or replace. If the job differs from what was described, we explain the change and get your approval first.
- Lock and test. We operate it from both sides with your keys so you can lock up confidently.
What does storefront lock repair cost?
Standard price: quoted before dispatch. The final price depends on whether an adjustment solves it or parts must be ordered (billed at standard rates), the lock body and backset, cylinder type, and whether you want the new cylinder keyed to your existing keys.
- Standard rate: orders placed 7 AM–8 PM
- After hours (orders placed 8 PM–7 AM): 1.5×
- Federal holidays (calendar date and observed date): 2×
- Federal holiday, after hours: 3×
- No weekend surcharge
- Mileage: $1.25/mile beyond 5 miles from the city center
Multipliers apply to everything on the job (service, labor, parts and hardware) except the flat $15 (inside city limits) or $25 (outside city limits) service call and mileage. The after-hours rate is set by the time the order is placed. Holidays are U.S. federal holidays, billed on both the calendar date and the observed weekday.
Online orders pay the $15–$25 service call at checkout as the deposit: $15 inside city limits, $25 outside. It is a flat fee added to the service price, and the time-of-day multipliers never apply to it. See our Payment & Deposit Policy and Cancellation Policy. See how our pricing works.
Can’t lock up at closing time?
A front door that won’t lock is one of the most urgent calls a business makes. We are open 24/7/365, with late-night and holiday calls at the published rates above, and generally aim to deploy within about one hour in Nashville, Murfreesboro, Franklin and the other core metro cities when feasible. If a part has to be ordered, we secure the door first where possible. That timing depends on demand, availability, traffic, weather, location and job complexity, so it’s a goal rather than a promise.
After a break-in, see our break-in lock repair service for securing damaged doors.
Storefront lock FAQ
Can you rekey my storefront lock instead of replacing it?
Usually, yes. The keyed part of a storefront lock is a mortise cylinder that can be rekeyed or swapped. If the lock body itself works, rekeying the cylinder is often the simplest way to cut off old keys.
Why does my key turn but the storefront bolt won’t lock?
Common causes are a worn or incorrect cylinder cam, a broken lock body, or a door that has sagged so the bolt hits the frame. We test each part to find which one has failed.
Can you install a deadbolt on a glass door that doesn’t have one?
Many aluminum storefront doors are prepped for a narrow-stile deadlock even if one isn’t installed. If yours isn’t, we’ll tell you what the door can accept before doing any work.
Do storefront locks come in different sizes?
Yes. Narrow-stile locks come in different backsets, and cylinders come in different lengths and cam styles. We measure your door to match them.
Can my storefront cylinder be on a master key system?
In most cases, yes. A mortise cylinder can be pinned to work with a master key system so managers and staff have the appropriate access.
Do you fix the push paddle on a storefront deadlatch?
Yes. Broken paddles, push handles and levers on deadlatches can often be replaced without changing the whole lock, depending on the model.
