Commercial Rekeying

The renovation is finished and the contractors have gone, along with the loaner keys they used for six weeks. Trades, delivery drivers and an inspector all came through, and the front door still answers to the key that was passed around the site.

In plain words

Commercial rekeying changes the pins inside a business's existing lock cylinders so that a new key operates them and every earlier key stops working, while the hardware itself stays on the door. The locksmith works from a list of the openings the business controls and the people who need to pass through each one, sets the cylinders to fresh combinations, cuts keys to match and records which key opens which door. Because nothing is replaced unless it is worn, a whole premises can be brought back under control in one scheduled visit, with the doors locking and unlocking exactly as before but answering only to keys you have counted.

The call
A key turned up in the parking lot with the shop's name on its fob. It came back to you, which is lucky, but it means keys are leaving the building on rings you have never seen, and the shop's locks have not changed since opening day.

How the visit goes

  1. Scene 1

    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.

  2. Scene 2

    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.

  3. Scene 3

    A routine for the next departure

    Turnover stops being a security event once there is a procedure for it. When someone leaves, their key is collected against the register and ticked off; if it cannot be produced, the chart shows exactly which cylinders that key opened, and only those are dealt with. Businesses that chose interchangeable cores can go further: the manager takes the control key from the safe, swaps the affected core for a spare in less time than a coffee break, and the locksmith repins the removed core at leisure for the next time. Either way the response is measured and specific, and the front door is never left answering to a key that walked out with a former employee.

What shapes the quoteAshburnham Lock Experts

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.
Number of cylinders
The count of openings drives the quote more than anything else: each cylinder is removed, repinned, refitted and tested individually, so a three-door shop and a twelve-office suite are very different jobs.
No existing chart or keys
When nobody knows what the current keys open, the locksmith reads and records each cylinder before planning the new keying, and that reconstruction is time in the quote.

Questions we hear most

Does stamping keys 'do not duplicate' stop people copying them?

Not reliably. The stamp is a request, and any key on a standard blank can be copied by anyone with the blank and a machine. What does work is controlling the blank itself through a restricted keyway, or controlling access to the lock through interchangeable cores and a tight register. Stamping still has a place: a serial code on each key, instead of the business name, lets you track it without telling a finder where it fits.

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.

What is a keying chart and why does it matter afterwards?

A keying chart is a plain list of every opening, the key group that operates it, the code stamped on those keys and the number issued. Months later it lets you answer exactly which doors a missing key opened, and it lets a locksmith add a new door to the system without changing anything else. Keep it with the key register, somewhere locked, with a copy off site.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 64 in 100 homes · older homes
  • About 64% of homes in Peterborough were built in 1980 or earlier, according to the 2021 Census.Older homes tend to have had many hands on their doors: owners, tenants, tradespeople, family. A locksmith visiting such a house pays attention to who holds keys now, and rekeying or a keyed-alike set often matters more than any new hardware.
  • Single-detached houses make up about 57% of homes in Peterborough (2021 Census).In a mixed area, a locksmith's advice bends to the building. For a house, the side door and garage entry get attention. For an apartment, the suite door's closer, strike and viewer do. The principle is the same: look at how the door is actually used.
