Lock Rekeying

Your roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring.

In plain words

A rekeying visit follows a straightforward order. First the locksmith confirms you are entitled to change the locks, which for an owner is identification and for a tenant includes the landlord's agreement. Next comes a walk around the house to list every door to include, read the keyway on each cylinder and check its condition. The cylinders come out one at a time, are pinned to the new key and go back in. Every door is then tested with the new key and with the old one, spares are cut and tried in each lock, and you receive a note of what was done.

Sound familiar?Cambridge

The call
Every copy of your house key seems to work a little differently. One needs a jiggle, another sticks halfway, and the original wore down years ago. The lock itself is fine; the keys have drifted so far from each other that none fits cleanly.

How the visit goes

  1. Scene 1

    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.

  2. Scene 2

    Taking the cylinder out of the lock

    Each type of lock releases its cylinder in its own way, and the locksmith works door by door, finishing one before opening the next, so every entry stays lockable throughout. On a knob or lever set, the handle comes off after a retaining clip or set screw is released, and the cylinder slides out of the handle. On a deadbolt, the interior thumb-turn and housing are removed and the cylinder is withdrawn from the outside body. On an older mortise lock, a small set screw on the door edge is backed out and the cylinder unthreads from the case. Nothing is pried or forced; the door and trim stay untouched throughout.

  3. Scene 3

    Looking after a freshly pinned cylinder

    A cylinder that has just been rekeyed turns as smoothly as it ever will, and a little care keeps it that way. Once or twice a year, a puff of whatever lubricant the cylinder maker specifies into the keyway and a few turns of the key is all it needs, since some current cylinders use oil while too much graphite can itself gum a cylinder. When you need more copies, cut them from one of the locksmith's originals rather than from a copy, because each generation drifts a little from the true depths. A key that starts to need a jiggle is the cylinder asking for a clean and a new key, not a sign of anything serious.

What shapes the quotePreston Locksmith Co.

Mailboxes, padlocks and cabinets
Small cam locks on mailboxes and cabinets are usually replaced rather than repinned, and padlocks vary in whether they can join the house key; each of these is priced as its own item.
Mismatched keyways needing a cylinder swap
Where one door's cylinder cannot take the key the other doors share, a compatible replacement cylinder is fitted and pinned to match, and that hardware appears as its own line in the quote.
Access to each door being rekeyed
A rekeying visit goes smoothly when every door is reachable without delay: an empty unit, a cleared hallway, or someone available to let the locksmith into each room. Locked common areas, tenants who are out, or furniture blocking a cylinder all add time the locksmith accounts for on site.

Good questions about locks

One of my locks is stiff and worn. Can it still be rekeyed?

Often the stiffness is grit, old oil and tired springs rather than real wear, and those are handled while the cylinder is on the bench: the plug is cleaned, new springs go in with the new pins, and a dry lubricant finishes it. If the plug has worn oval or the housing is damaged, the locksmith shows you and suggests a replacement cylinder pinned to the same key, rather than fresh pins in a lock that will keep dragging.

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.

I am a landlord. Should I rekey between tenants?

Many landlords do, and it removes the question of whether every copy came back. The locksmith rekeys the unit's cylinders so the incoming tenant holds the only working keys, cuts the copies you want, and notes the count for your move-in record. Because provincial tenancy rules expect the tenant to be handed replacement keys whenever a landlord changes a lock, the visit ends with keys for both of you and a clear list of which doors were done.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 48 in 100 homes · mixed ages
  • About 48% of homes in Cambridge were built in 1980 or earlier, according to the 2021 Census.Mixed housing stock keeps a locksmith versatile. A morning might be a heritage mortise lock rebuilt and an afternoon a smart lock paired to a phone on a steel door. The same care goes into both, with tools and parts for each.
  • Single-detached houses make up about 57% of homes in Cambridge (2021 Census).Mixed housing brings mixed hardware ages as well as types. A locksmith may rebuild a mortise lock on a semi-detached house and then set up a keypad on a townhouse door across the road, and treats each with the care its owner expects.
