Commercial Rekeying
The renovation is finished and the contractors have gone, along with the loaner keys they used for six weeks.
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.
How the visit goesThe office has been reshuffled twice since the locks were last touched. Reception can open the server room, the warehouse crew has a key to accounting, and the chart that once explained who could open what has not been seen since the move.

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.
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
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.
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.
Several locations
Rekeying two or three sites onto one keying plan means travel between them and a chart that spans buildings, quoted per site plus the shared design work.
What to have ready
- Are any cylinders stiff, loose or hard to turn at the moment?
- Can you gather every existing key so they can be read on site?
- Does your lease say anything about changing locks or giving the landlord a key?
Commercial Rekeying: questions
QuestionsWhat happens with our fire exit doors and panic bars?
The outside cylinder on an exit door controls entry only, and it can be rekeyed like any other. The inside stays as it must: one push or one turn, no key, no special knowledge, on the exit door itself and on any door on the way to it. A locksmith will not add a keyed device to the inside of an exit, and will point out one if it already exists.
What is the difference between rekeying a business and replacing its locks?
Rekeying keeps every lock on the door and changes only the pins inside the cylinder, so a new key works and the old ones stop. Replacing swaps the hardware itself. Commercial cylinders are made to be repinned many times, so rekeying suits any lock in sound condition and leaves the levers, trim and door untouched. Replacement is chosen door by door for cylinders that are worn, corroded or too light for what they protect.
What is an interchangeable core and why is it suggested for staff turnover?
A small-format interchangeable core is a small figure-eight cylinder that slides out of the lever, deadbolt or padlock when a control key is turned, with no tools needed; larger doors sometimes use a large-format core with a different profile instead. A manager keeps the control key in the safe and a few spare cores on hand, so a missing key means the core is swapped in moments and repinned later. For a business with frequent staff turnover, it turns a call-out into a routine.
