Commercial Rekeying in Port Severn
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.
Commercial Rekeying
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.
How the visit goesA break-in overnight took the cash float and a staff member's bag with her work keys inside it. The glass is being replaced this morning, but the key that opened the door yesterday will still open it tonight unless the cylinders are changed.

How the visit goes
A walk of every door and lock
The locksmith walks the premises with you and lists every opening that should be in the plan: the customer entrance, the receiving door, offices, stockroom, cash room, server closet, the mailbox, cabinets, and any padlocks on gates, compounds or roll shutters. Each lock is identified by type, since a mortise cylinder in an aluminum storefront door, a key-in-lever set on an office, a rim cylinder on a back door and an interchangeable core in a stockroom each come out and go back in differently. The keyway and the maker's mark are noted, and the condition of each cylinder is checked, so the list from the walk is what the quote and the work are built on.
Swapping interchangeable cores
Where the business already runs on interchangeable cores, the door hardware never comes apart. The control key goes into the figure-eight core, turns a few degrees, and the whole core slides out of the lever or padlock in one piece. A freshly combinated core goes in the same way, the operating key is tried, and that door is done. The old cores travel back to the bench to be repinned for another opening or held as spares. This is what makes cores so well suited to businesses with steady turnover: a single control key, kept in the manager's safe rather than on a ring, is all it takes to change a lock.
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
Same fees day, night or weekend
1Interchangeable cores versus repinning
Cores swapped with a control key are the shortest work on site, while cylinders that must come apart on a bench take longer. Supplying spare cores for the manager to hold is priced as its own line.
2Landlord 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.
3A master key plan
Pinning cylinders to accept both a change key and a master, and designing the chart so no key opens a door it should not, is more work per cylinder than keying everything alike.
Commercial Rekeying: questions
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.
What information should I have ready before the locksmith arrives?
A list of the doors and other locks you want included, a copy of the lease or the property manager's contact, every existing key you can find, and a rough idea of who needs to open what. Note which doors, if any, are interchangeable cores and where the control key is. Knowing your quiet hours and who opens up in the morning helps the locksmith plan the order of work and the key handover.
Is a restricted keyway worth it for a business?
A restricted keyway uses blanks that only the locksmith or authorized source can obtain, released against whatever that key-control program requires, a signed letter, card, signature record or factory authorization naming who may order keys. Hardware stores and kiosks have no blanks, so copies are far harder to get without your say-so. It costs more per key than a standard keyway and is most valuable where keys pass through many hands, such as retail with part-time staff, shared premises or anywhere the count of copies has drifted before.
