Commercial Rekeying
The office has been reshuffled twice since the locks were last touched.
In plain words
For most business doors, rekeying is the sensible middle path between doing nothing and buying new hardware. Commercial cylinders are built to be repinned many times, and a lever set, mortise lock or storefront cylinder in decent condition has years left in it. Rekeying keeps the finish, the door preparation and the handles you already have and changes only the small brass pins inside. Where a cylinder is worn, corroded by winter salt or too light for the room behind it, the locksmith says so and offers a replacement for that door alone; the rest are rekeyed to the new plan.
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


Choosing the window and the order of doors
The last part of the assessment is practical: when can the work happen, and in what order. A retail shop may prefer the hour after closing; a restaurant, the mid-morning lull; a warehouse, the gap between the last outbound truck and the night shift. The locksmith also asks about deliveries, the cleaning crew, the alarm monitoring company and anyone else who holds a key and needs a new one before their next visit. From this comes a sequence, typically the doors staff use least first and the main entrance last, so there is always a working, lockable way in and out while the cylinders are being changed.
Door by door, never a gap
The sequence agreed at the assessment is followed on the day. The locksmith finishes one opening entirely before beginning the next: cylinder out, repinned, refitted, tested with both the new key and the old, and locked again. Only then does the next door come apart. The main entrance is usually left for last and done while someone from the business is present, so there is never a moment when the premises has a door that will not lock. Staff who are working during the visit are handed their new key before the door they use is changed, and a short note goes to anyone off shift about where to collect theirs.
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
Cylinders that need replacing
Where a worn, corroded or low-grade cylinder is better replaced than repinned, the new part is added for that door alone, and the locksmith points it out before the work begins.
After-hours or split visits
Work done after closing, before opening or split across two visits to suit trading hours costs the same amount as a single daytime block. The exact figure is confirmed on site once the number of cylinders and the keying plan are known.
Padlocks, cabinets and mailboxes
Small locks add up. Each padlock repinned to the door key, each cabinet keyed alike and each mailbox cylinder replaced is listed on its own so you can decide what to include.
What to have ready
- Do you have a current list of who holds keys?
- Are any cylinders stiff, loose or hard to turn at the moment?
- Do you want one key for everything, or separate groups with a master?
Commercial Rekeying: questions
QuestionsWill rekeying affect our alarm system or card readers?
Mechanical rekeying leaves electronics alone: alarm panels, card readers and keypads keep their codes and credentials. What changes is the list of people holding keys, and it is worth updating the alarm company's keyholder list and retiring the codes of anyone who has left at the same time, since keys and codes usually walk out together. Where a door has both a card reader and a keyed override, the override cylinder is rekeyed with the rest.
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.
Can padlocks, cabinets and the mailbox go on the plan too?
Yes. Gate, cage and shutter padlocks that accept repinning can share the back-door key, and the locks on filing cabinets, drawers and display cases can be grouped so the people who work at them carry a single key while the manager holds a separate one. Mailbox cylinders are small and are usually swapped for new rather than repinned. Everything is entered on the chart, so one document covers the whole premises.
