Everyday Commercial Locksmith Complaints We Fix

We've handled every exit hardware and access control issue a business can run into. Here are the problems our clients call us about most often.

🚪

Push Bar Won't Latch Properly

A push bar that releases but doesn't latch the door closed usually has a worn internal latch mechanism. Left unaddressed, the door can swing open unexpectedly and compromise building security. We inspect and repair or replace the failing internal components.

💪

Exit Device Requires Excessive Force to Open

A push bar that needs a hard shove instead of light pressure usually has a worn spring or misaligned latch assembly. This is also a code violation, since exit hardware must operate with minimal effort. We diagnose the internal cause and restore proper operation.

🔒

Locked Out of the Business

A lost key, jammed cylinder, or broken key stuck in the lock can shut down access at the worst possible time. Every minute locked out is lost business and frustrated staff or customers waiting outside. We provide fast commercial lockout service to get doors open again.

🔑

Employee Left With a Working Key

A staff departure without a rekey means a former employee may still have working access to the building. This creates a real security gap that grows the longer it goes unaddressed. We rekey affected doors quickly so old keys stop working immediately.

🗝️

Master Key System Is Disorganized

A key system that grew without documentation over the years often means nobody knows exactly who has access to what. This creates liability risk and makes it hard to respond quickly to a lost key. We assess the current system and redesign a clear, documented hierarchy.

🔥

Exit Device Failed a Fire Inspection

An inspector flagging exit hardware as noncompliant usually means the wrong category of device is installed for the door's fire rating. Operating with noncompliant hardware creates real liability exposure until it's corrected. We assess the door and install hardware that meets code.

🚨

Alarm Trips Unexpectedly on Exit Door

An exit device alarm module that triggers without cause usually has a wiring fault or a sensor that has drifted out of calibration. False alarms train staff to ignore real ones, which defeats the purpose of the alarm. We diagnose and repair the alarm module or replace it if needed.

🏗️

New Doors Need Egress Hardware Installed

New construction or a renovated exit route without proper egress hardware cannot legally open for business. Skipping proper hardware selection risks a failed inspection down the line. We assess occupancy load and fire rating before installing correctly graded hardware.

🏢

Access Control Doesn't Match Business Growth

A business that has added doors or departments faster than its key system can track often ends up with inconsistent or overly broad access. This makes it hard to control who can enter sensitive areas. We redesign the key hierarchy or recommend electronic access control to match how the business actually operates.

Reviews

Straight From the People We Served

Harold V.

Push bar fixed in under an hour

Our front exit push bar had started sticking and I was worried it would fail an inspection. The technician from Prime Windows Toronto opened it up, replaced a worn latch component, and had it working smoothly again fast.

Simone A.

Explained panic hardware versus fire exit hardware

I had no idea these were two different regulated categories until Prime Windows Toronto walked me through it. Turns out our previous installer used the wrong type on our fire-rated door and it was quietly a compliance issue for years.

Walter B.

Great master key system, took a bit longer to document

The redesign of our key hierarchy was thorough and exactly what we needed after years of nobody knowing who had which key. Documenting every door and holder took an extra day beyond the original estimate, but the result was worth it.

Naomi C.

Same day rekey after an employee departure

We needed locks rekeyed fast after a manager left on bad terms. They came out the same day and had every affected door rekeyed within a couple hours. Genuinely relieved at how quickly it happened.

Derek P.

New push bar installed correctly the first time

Our renovated exit route needed a fresh push bar and the technician confirmed occupancy load and fire rating before installing anything. Passed inspection without a single issue, which our contractor said doesn't always happen.

Ingrid F.

Honest about repair instead of replacement

I was expecting to pay for a whole new exit device but Prime Windows Toronto checked the internals first and found a simple repair would do the job. Saved us a good chunk of money and it still works perfectly months later.
