Locksmith Access Control Cost Calculator
Prices an access control installation, where the electrical failure mode has to be decided before anything is ordered.
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. An access control door is several components rather than a lock: a credential reader, a controller, a locking device, a power supply with battery backup, a door position switch, a request to exit device and cabling to all of it. The labour is largely pulling cable and commissioning rather than fitting hardware, so the cost scales with how far the door is from the controller and power and whether there is a route for cable at all.
What moves the number
- Cable routing distance and whether there is a practical path, which is most of the labour.
- Fail safe against fail secure locking, which has to be decided by the door's role.
- Number of doors on one controller, since the head end cost spreads.
- Integration with the fire alarm, which is required where the locking affects egress.
Where this one goes wrong
Fail safe and fail secure is the decision that matters and it is frequently got wrong. A fail secure lock stays locked when power is lost, which suits protecting a room. A fail safe lock releases when power is lost, which is what an egress door on a locked stair or a door that must free up in an alarm needs. Getting it backwards produces either a door that unlocks in a power cut or, far worse, one that stays locked when the building is on fire. Electrically locked egress doors generally have to release on fire alarm activation and on loss of power, and must retain a mechanical means of egress, so this is a code question rather than a specification preference. Reader mounting height and operating force also fall under accessibility requirements on accessible routes.
Before you quote
- Decide fail safe or fail secure from the door's egress role, not from convenience.
- Confirm fire alarm interface and power loss behaviour for any egress door.
- Check reader height and operating force against accessibility requirements.

Questions
About this calculator
What is the difference between fail safe and fail secure?
Fail secure stays locked when power is lost; fail safe releases. Which you need is determined by the door's role: a store room wants fail secure, while a door on an egress route that must free up in an alarm or a power cut needs fail safe. Getting it backwards is the common and potentially serious error.
Does an access controlled door have to unlock in a fire?
Where the locking affects egress, generally yes, and it usually has to release both on fire alarm activation and on loss of power, with a mechanical means of egress retained. The specifics come from the adopted building and life safety codes, so they need confirming for the jurisdiction and occupancy.
What drives the cost of adding a door to access control?
Mostly cabling. The reader, lock and controller are predictable, but running cable from the door to the controller and power, through an existing building, is where the hours go. A door close to the head end is far cheaper than one across the site, and several doors share the controller cost.
The formula
total = hours x people x rate + parts + call-out, then sales tax

How to use this calculator
- Hours on site (h). Enter your own figure; the page starts at 0.8 h.
- People needed. Enter your own figure; the page starts at 1.
- Labour rate charged ($). Enter your own figure; the page starts at $120.
- Parts and materials ($). Enter your own figure; the page starts at $35.
- Call-out or diagnostic fee ($). Enter your own figure; the page starts at $95.
- Sales tax (%). Leave at zero if you are quoting before tax.
The result updates as you type, so you can try a figure, see what it does to estimated total, and change it back. Nothing you enter is sent anywhere or saved.
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.
