Lock Rekeying in Sherwood
Three months of renovation are finally done.
In plain words
What you keep after rekeying is almost everything. The deadbolt, the handle set, the finish that matches your door hardware, the strike plate and the holes in the door all stay exactly where they are, which matters on an older door where new hardware rarely lines up with old mortises. What changes is a handful of brass pins a few millimetres long inside each cylinder, and the key in your pocket. The work is done on site, one cylinder at a time, so the house is never left with an unsecured door, and worn springs or a sticky plug can be dealt with while the cylinder is already apart.
How the visit goesYour basement tenant has given notice, and a new one arrives on the first. The lock on the separate entrance works perfectly well. You simply want a fresh key for the incoming tenant and for the old one to be retired.

How the visit goes


Smart locks and user-rekeyable cylinders
Modern hardware gets its own look. Many keypad or app-controlled deadbolts have a conventional override cylinder behind a cover that can be rekeyed to the house key so the backup key is not a stranger on your ring, though some models are key-free and use an external battery backup instead. Some residential cylinders are designed to be reset by the owner with a small tool and a working key; the locksmith checks whether one has been reset correctly and whether it accepts the new key. Where a smart lock is being kept, codes are reviewed at the same time so a departed keyholder's code goes the way of their key.
Resetting a user-rekeyable cylinder properly
Some residential deadbolts and handle sets are built so the owner can change the key with a small tool, a working key and the new key. They save a bench session, and they also go wrong in a particular way: without a working key of the correct type, or with a key from the wrong keyway, the reset stalls partway. The locksmith carries the reset tool and the reset procedure for these cylinders, confirms the keyway matches the new house key, and completes the change so the cylinder accepts the new key and rejects the old one. If the mechanism has been damaged by a forced reset, it is replaced with a standard cylinder and pinned to match.
Knowing when to rekey again
Rekeying is not a once-in-a-lifetime event; it is a habit tied to changes in who holds keys. The moments to think about it are the same ones that brought you here: a move, a tenant or roommate change, a key lost with anything identifying the address, a contractor who has finished, or a relationship that has ended. Between those events there is nothing to schedule. Because the house is now on a known system with a record, a later rekey is a shorter visit, and any new lock you add along the way can be pinned to the existing key so the household never drifts back to a ring full of mismatched keys.

What affects the quote
No working key for a door
When a cylinder must be shimmed, decoded or picked open before it can be repinned because no key exists for it, that extra step is included in the quote for that door.
Upgrades chosen during the visit
Some people take the opportunity to replace a double-cylinder deadbolt with a thumb-turn model, add a reinforced strike or move to a heavier deadbolt. None of it is needed to rekey; each is a separate line.
How many cylinders are included
Each cylinder is removed, pinned and tested on its own, so a single deadbolt and a house with six exterior locks plus a shed and a gate are very different visits, and the quote follows the count.
What to have ready
- Do you have a working key for every lock, or is there a door with no key at all?
- Do you own the home, rent it, or manage it for someone else?
- Is there a shed, gate, mailbox or padlock you would like on the same key?
Lock Rekeying: questions
QuestionsWill my door hardware look any different afterwards?
No. The work happens inside the cylinder, so the bolt, handle, finish and strike plate stay exactly as they are, and nothing new is cut into the door. The only visible change is the key in your hand. If a cylinder does have to be replaced, because its keyway is incompatible with the others or it has worn out, the locksmith picks one in a matching finish so the door keeps a consistent look.
How often should locks be rekeyed?
There is no calendar for it. What matters is who holds a key, not how many years have passed. Think about it when occupancy changes hands, when someone who had a key no longer needs one, or when a ring goes missing along with something that shows where you live. Between those moments a well-kept cylinder may need no scheduled care, and when it does, use whatever that cylinder's maker specifies. With the doors already on one recorded system, any repeat is a short piece of work.
Should I rekey when I move into a new home?
It is the single most common reason to rekey, and a sensible one. A resale home has typically passed through owners, agents, inspectors, cleaners and trades, any of whom may have had a key cut. A newly built home has been opened by construction crews using a builder's key. Rekeying on move-in means the only working keys are yours, and the same visit can bring every exterior door onto a single key, retiring the assorted keys you inherited.
