Locksmith
Commercial Locksmith Cost Calculator
Prices commercial lock work, where life safety and accessibility requirements decide what may be fitted.
Result
A planning estimate, not a quote. Access, the age of the equipment, what is found once it is opened up and local labour rates all move the real figure, sometimes a long way.

Time, hardware and the call-out, at a rate reflecting that commercial hardware is heavier, more expensive and more regulated than residential. The labour is longer because mortise locks, exit devices and closers involve more fitting and adjustment than a cylindrical lockset, and because the work often has to happen outside trading hours. What genuinely separates commercial work is that the hardware on a door is frequently determined by code rather than chosen: egress, accessibility and fire rating requirements each constrain what may be fitted, and they apply together.
What moves the number
- Whether the door is a required exit, in a rated assembly, or on an accessible route, since each adds requirements.
- Hardware type, as mortise locks and exit devices take considerably longer than cylindrical locksets.
- Out of hours working, which is often necessary and priced accordingly.
- Whether the site runs a keying system that new cylinders have to fit into.
Where this one goes wrong
The requests that cause trouble are the ones aimed at stopping people going out. A chain, a padlock, a keyed deadbolt or a thumbturn removed from an exit door defeats egress, and it is both a code violation and the reason people die in fires. When a business owner asks for it because of theft or unauthorised exits, the answer is delayed egress or alarmed hardware where permitted, not a lock that traps people. Fire rated doors are the other area: listed hardware and a working closer are part of what makes the assembly rated, so substituting unlisted hardware or disabling a closer voids it. Accessibility requirements on operable parts apply on accessible routes regardless of what looks better.
Before you quote
- Establish the door's role, rating and accessibility status before specifying.
- Refuse hardware that defeats egress and offer a compliant alternative.
- Use listed hardware and a functioning closer on rated assemblies.

Questions
About this calculator
Can I lock a fire exit to stop people using it?
Not with anything that prevents egress. Chains, padlocks and keyed locks on exits are code violations and a genuine life safety hazard. Where unauthorised use is the problem, alarmed exit hardware or delayed egress devices where permitted address it while still letting people out, which is the compliant answer.
Why is commercial hardware so much more expensive?
It is built for far higher cycle counts, it is often required to be listed for fire rated assemblies, and it includes components residential doors do not have such as exit devices and closers. Fitting takes longer too, particularly mortise work, and the job frequently has to happen outside trading hours.
What makes a fire door assembly rated?
The door, frame, hardware and closer together, all listed and correctly installed. Substituting unlisted hardware, propping the door or disconnecting the closer defeats the rating even though the door itself is unchanged. That is why hardware on a rated door is a compliance matter rather than a preference.
The formula
total = hours x people x rate + parts + call-out, then sales tax

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Hours on site | 0.8 h |
| People needed | 1 |
| Labour rate charged | $120 |
| Parts and materials | $35 |
| Call-out or diagnostic fee | $95 |
| Sales tax | 0% |
What comes out
| Result | Value |
|---|---|
| Estimated total main result | $226 |
| Labour | $96 |
| Before tax | $226 |
| Sales tax | $0 |
About $226: $96 of labour, $35 of parts and a $95 call-out.
How sensitive the answer is
Holding everything else steady and changing only labour rate charged, this is what happens to estimated total. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Labour rate charged ($) | Estimated total |
|---|---|
| $60 | $178 |
| $90 | $202 |
| $120 example above | $226 |
| $180 | $274 |
| $240 | $322 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.
