Five-Star Rated Commercial Lock Rekeying Services in Delaware
A rekey is often confused with a replacement, and the difference is worth understanding before anyone signs off on new hardware. Rekeying keeps the lock body, the finish, and the fit in the door, and changes only the internal pins that decide which key turns the plug. That makes it the natural answer when access has to change but the doors are sound. It also makes it fast, because cylinders come out and go back into the same holes. A business that has just changed staff, moved in, or ended a contract usually needs exactly this and nothing more.
Who calls us for this
An office manager in Dover collects three keys from a departing employee and wants to know what those keys could still open. A restaurant owner in Lewes has a back door that four former staff members used for deliveries. A property manager in Georgetown takes over a building where the previous tenant kept the keys. A clinic in Seaford rotates staff twice a year and wants that rotation to happen without new hardware. A warehouse in Harrington needs every loading door on one key while keeping the office on another. A shop in Smyrna needs the outside locks changed while the interior doors stay as they are.
How the visit goes
The visit begins with a count rather than a tool: how many exterior doors, how many keys are in circulation, and who should hold which one. Every cylinder is checked for type, since a rim cylinder, a mortise cylinder, and a key-in-knob set are rekeyed differently.
Cylinders are removed, opened, and repinned to a new key, then reinstalled and tested with the new key and with an old one to prove the old one is dead. Where a master key structure is wanted, the pinning is built around it from the start. The new keys are cut at the end, and a written record of who holds what is left with the manager.

Inside a pin tumbler cylinder there is a row of bottom pins, a matching row of driver pins, and springs above them. The key lifts each bottom pin so the break between the two rows sits exactly at the plug line, which is what allows the plug to rotate. Rekeying replaces the bottom pins and sometimes the drivers so that a different key height produces the same alignment.
A master key system adds a second set of heights so one key can lift every pin to a shear line while a subordinate key works only some cylinders. Keyways, cylinder lengths, and the number of pins all constrain what is possible, so the plan is settled before the first cylinder comes off the door.

The number of doors decides how the work is sequenced, and a building that cannot close during the day is usually handled before opening. The key structure is the largest decision, because a master key plan has to account for every door a person might need and every door they should not open.
Whether keys have gone missing rather than been returned affects the urgency, since an unreturned key is the reason for the call in the first place. The condition of the existing cylinders matters, and a cylinder that is worn or damaged may need to be replaced rather than repinned. Finally, the tenant and landlord relationship decides who authorizes the change.
Before we arrive
Count the exterior doors and note which interior doors carry keys, because the plan is built from that list. Gather every key that staff still hold, or note which ones are missing. Decide who should open which door before the visit, and write it down rather than deciding at the door. Confirm who is authorized to approve the work if the building is leased. Have one person available during the visit who can answer questions about how the building is used during the day.

A rekey is the right moment to fix a key structure that has grown by accident. Buildings accumulate keys over years, and it is common to find three keys doing the work one should do. Before any cylinder is touched, draw the building on a sheet of paper and mark who needs which door. From that sketch a simple hierarchy follows: one manager key for the whole building, one key for staff entrances, one for the mechanical room. It takes nothing to plan that way, and it prevents a future where a single lost key forces a second rekey of everything.

Where we work from
Commercial rekeys are carried out across Kent County and Sussex County from the office at 18 SW Front St Ste 103, Milford, DE 19963. Milford sits on the Mispillion River, which separates parts of the two counties, so business routes leave the shop in both directions. Kent County work covers Dover, Camden, Magnolia, Felton, Harrington, and Smyrna. Sussex County work covers Georgetown, Lewes, Milton, Seaford, and Bridgeville. Coastal businesses deal with more corrosion on exterior hardware, while inland buildings see more movement in wooden doors.
Frequently asked questions
What is the difference between rekeying and replacing?
Rekeying changes the pins inside the existing lock so a new key works. Replacing removes the hardware and installs something different.
Do I need to rekey every door?
Usually only the exterior doors and any interior door that limits access to something valuable. The count is decided at the start.
What happens to the old keys?
They stop working. Every cylinder is tested with an old key afterward to confirm it no longer turns.
Can one key open the whole building?
Yes, if a master key structure is built. Subordinate keys can be limited to the doors each person actually needs.
Is rekeying enough after a staff member leaves?
It is the usual answer for exterior access. If a key cannot be accounted for, every cylinder that key opened should be rekeyed.
Does rekeying fix a door that will not latch?
No. That is an alignment or closer issue, and it is worth correcting so the new pins are not fighting a bad fit.
Can it be done outside business hours?
Yes. Early morning and after-close visits keep the disruption away from customers and employees.
How are new keys handed out?
A written record of who received which key is left with the manager, and it makes the next rotation quick to plan.
