Lock Rekeying
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.
Lock Rekeying
In plain words
Moving into a home is the moment most people first hear about rekeying, and it is the most sensible time to do it. A resale house has usually passed through owners, real estate agents, home inspectors, cleaners and trades, each of whom may have held a key at some point. Rekeying every exterior cylinder on move-in day means the only keys that work are the ones cut for you, and the same visit is a chance to put every door on one key so the coffee tin of mystery keys can go in the recycling.
How the visit goesEvery 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
Walking every door that should be included
Before a single cylinder comes out, the locksmith walks the property with you and lists each opening: the front door, the back and side doors, the door from the garage into the house, a walkout basement, a gate with a keyed latch, a shed, a mailbox, and any interior door you want on a key. It is surprising how often the garage's side door or the storm door is forgotten and left on the old key. The list becomes the plan for the visit and, at the end, the record of what was done. A door that is not on the list is not rekeyed, so the walk is worth two careful minutes.
Bringing several doors onto one key
Keying doors alike is the same operation repeated with the same new key. Once the first cylinder is pinned and proven, the locksmith removes the second, follows the plug out, and loads bottom pins to the identical depths so the same key operates it, and so on around the house. Where a door carries a cylinder from a different keyway family, that cylinder is exchanged for a matching one in the same finish and then pinned to the house key. The result is one key on your ring that turns every exterior door, with the individual locks unchanged in appearance and function.
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
Same fees day, night or weekend
1One key group or several
Keying every door alike is the simplest plan. Setting up separate keys for a basement suite, an office or a shed adds a group to pin and label, and the quote shows that as separate work.
2Condition of the existing cylinders
A clean cylinder is repinned as it is. One with collapsed springs, a plug packed with old oil or a worn housing needs service or replacement while it is apart, and that shows separately.
3Access 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.
Lock Rekeying: questions
How many new keys will I get, and can I get more later?
As many as you ask for, cut on site from the fresh pinning and tested in each door they should open; two or three is typical for a household. More can be cut later. When you do, bring one of the locksmith's originals to be copied rather than a copy of a copy, since every generation strays slightly from the intended depths. If any key is a restricted type, additional copies come from the record kept for that system rather than from a hardware store.
My locks are different brands. Is that a problem?
Not a problem, just a detail to plan around. What matters is the keyway, meaning the profile of the slot the key fits, rather than the name on the lock. Different makers sometimes share a profile and sometimes do not. Where two cylinders cannot accept the same key, one is exchanged for a compatible cylinder in the same finish and pinned to match. From the outside the door looks the same and from your pocket it is one key.
Can the entry door of my condo suite be rekeyed?
Often, but check with your property management first. Condominium corporations have a right to enter a unit on reasonable notice, and without notice in an emergency, and many buildings ask that suite doors stay on a system the corporation can open or that a key be lodged with management. Lobby, garage and locker-room doors belong to the corporation and are theirs to manage. A locksmith will ask about your building's rule and work within it.
