Commercial Rekeying

Two people left over the summer and the keys they handed back came up one short. Nobody is sure whether the missing key was for the front door, the stockroom or both, and the sign-out sheet stopped being filled in a year ago.

In plain words

Losing a master key exposes every door it opened, and a commercial rekey brings that exposure back to zero. The locksmith first works out which level the missing key sat at: a single change key affects one or two cylinders, while a master reaches every lock in its group. Only the affected cylinders are repinned, which keeps the rest of the system intact and the response proportionate. Where a keying chart exists the work is precise; where the chart has been lost, the visit begins by reading and recording the existing cylinders so the new plan starts from facts rather than memory.

Sound familiar?

You have just signed the lease on a unit the previous tenant ran for a decade. The landlord handed over three keys, the back door wears a padlock nobody can open, and nobody can say how many front-door keys are still out there.

How the visit goes

How the visit goes

1
Reading the keys that already exist
Before deciding anything new, it helps to understand the old. Gather every key the business can find, including the ones with faded tape labels, and the locksmith reads them against the cylinders on the walk. Some will turn out to be duplicates of each other, some will belong to hardware that was replaced years ago, and some may operate doors nobody expected them to. Hardware-store copies stand out by their blanks and by the way they wear. This reading shows how far the key count has drifted and whether an old master still exists, and it lets the new plan retire everything found in the drawer rather than only the keys anyone remembered.
2
Storefront and mortise cylinders
Aluminum storefront doors carry a threaded mortise cylinder held by a small set screw in the door edge. The locksmith loosens the screw, spins the cylinder out, repins it, and threads it back to the same depth so the cam engages the deadbolt or hook bolt behind it and nothing else. Mortise locks in older office doors work on the same principle with a heavier lock body. On both, the depth and cam type matter as much as the pinning: a cylinder a turn too far in or a cam of the wrong shape will feel right in the hand but fail to throw the bolt, so each is cycled open and closed.
3
Adding a door without starting over
The pinning records kept from the visit mean the system can grow. When the business takes the unit next door, adds a storage cage or replaces a worn lever set, the new cylinder is pinned into an unused combination on the existing chart and handed a key from the right group, and nobody already carrying a key notices anything changed. That is the value of leaving reserve combinations in a master system rather than using them all up on day one. Keep the locksmith's reference number for the system with the chart, mention it when you call, and a single new door becomes a short visit instead of a fresh plan.

What affects the quote

1
How many keys are cut
Each key cut to code and stamped is counted into the quote. Two per door group for a small shop and forty for a warehouse shift are different numbers.
2
Restricted keyway
Moving to a patented, restricted keyway means new cylinders or cores rather than a repin of the old ones, and the blanks themselves carry a higher price than standard keys.
3
Landlord and base-building coordination
Suite doors that must accept both your key and the landlord's master, or work that needs the property manager on site, add coordination the quote allows for.

Same fees day, night or weekend.

Commercial Rekeying: questions

Advice · (289) 803-1633

How long should we set aside for a commercial rekey?

It depends on the count and the mix. A shop with a front door, a back door and a stockroom is a short visit; an office suite with a dozen lever sets, a master key plan and a mailbox takes a good part of a day. Interchangeable cores are the shortest of all, since they are swapped rather than repinned on site. The locksmith gives a time estimate at the assessment, once every cylinder has been counted.

How many keys should we have cut?

Count the people who need each group, add one spare per group for the safe, and stop there. Extra keys cut 'just in case' are the ones that end up unaccounted for. Because the keys are cut to code from the pinning records, more can be produced later to the same standard, so there is no need to stockpile on the day. Restricted keys are ordered by the named signatories when needed.

Can the aluminum storefront door on our unit be rekeyed?

Yes. The narrow stile of a storefront door houses a screw-in mortise cylinder secured from the edge, and it unthreads, is repinned and screws back in like any other. What the locksmith watches is the cam: it has to suit the hook or deadbolt mechanism inside the door and sit at the correct depth, or the bolt throws short. Weather-facing cylinders showing salt wear are pointed out so you can decide on replacement.

What the census means at the door

30%

Newer homes. About 30% of homes in Newmarket were built in 1980 or earlier, according to the 2021 Census.

New construction settles in its first years, and a door that closed perfectly at move-in can begin to catch as the frame finds its final position. A locksmith visiting a newer home adjusts strikes and hinges so the bolt throws freely again.

60%

A mix of homes. Single-detached houses make up about 60% of homes in Newmarket (2021 Census).

Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
