Most small businesses we visit still run on a handful of brass keys and a mental list of who has one. That works fine right up until it doesn't: an employee leaves on bad terms, a key goes missing at the beach, or the owner realizes nobody actually knows how many copies of the front door key exist. At that point the conversation shifts from "keys are cheaper" to "what would fobs cost us." Here is how we walk through that math with owners.
The real cost of a lost key
A key itself costs a few dollars to cut. That is not the problem.
The problem is that when a key leaves your control, the only way to be sure it no longer opens your door is to rekey the lock. For a single storefront with one or two doors, a locksmith visit typically lands somewhere in the low hundreds of dollars. If you have a front door, a back door, an office, and a stock room on the same key, it climbs from there. Do that twice a year because of staff turnover and you have quietly spent more than a basic access control system would have cost.
With a fob or card system, revoking access is a thirty-second task in software. The fob in the ex-employee's junk drawer becomes a piece of plastic. Nobody calls a locksmith, nobody hands out new keys to the remaining staff, and nothing about the door changes.
If your business has more than a couple of employees and any meaningful turnover, that one difference usually decides the question on its own.
Audit trails answer questions keys can't
A mechanical key tells you nothing. If stock goes missing or the alarm was left off overnight, a keyed door offers no evidence about who came and went.
An access control system logs every entry: which credential, which door, what time. We are careful to tell owners this is not about spying on staff. In practice the log mostly clears people. When something goes wrong at 9:40 p.m. and the log shows nobody badged in after close, you can stop wondering about your own team and start looking at other explanations. Pairing door logs with camera timestamps makes both systems more useful than either alone.
For businesses with compliance obligations, or landlords with cleaners and contractors coming through, the log stops being a nice-to-have and becomes the main event.
Door schedules do the remembering for you
The feature owners end up loving most is the one they didn't ask about: schedules.
A scheduled door can unlock itself at opening time and lock itself at close, every day, without anyone thinking about it. Staff fobs can work from 7 a.m. to 9 p.m. but not at 3 in the morning. A cleaner's fob can work Tuesday evenings only. The weekend manager can open the building without being trusted with a master key to the office.
None of this is possible with metal keys, where every credential is all-or-nothing, around the clock, forever.
We wrote earlier about why smart locks should keep working offline, and the same principle applies here: a properly installed access control system runs its rules locally at the door controller. If the internet drops, doors keep obeying their schedules and fobs keep working. You manage it from software; you do not depend on the cloud minute to minute.
When keys are still the right answer
We are not going to pretend every business needs this. A two-person shop with no turnover and one door is fine on keys. A business that shares a door controlled by the landlord may not be allowed to change the hardware anyway.
The tipping points we see are: more than four or five credential holders, any regular staff turnover, more than two doors on the same key, after-hours access for cleaners or contractors, or any incident where you found yourself wishing you knew who opened the door. Hit two of those and fobs generally pay off within a couple of years, then keep paying every time someone moves on.
Cost-wise, a small single-door system is typically in the low thousands installed, with multi-door systems scaling per door. Compare that honestly against your locksmith spend, key management headaches, and the risk carried by every unaccounted-for copy.
