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.

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.

The call
Your 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

  1. Scene 1

    Who is entitled to change the locks

    Rekeying decides who can enter a home, so the first check is about the person asking. A homeowner shows photo identification and something tying them to the property, such as a tax bill, a closing document or a utility statement. A property manager brings authorization from the owner. A tenant is asked whether the landlord has agreed to the change and will receive a copy of the new key, because tenancy rules here expect both sides to hold one. Where a unit is in a condominium, the locksmith asks whether the building has a rule about suite-door locks. None of this is an obstacle; it is the part of the job that protects the home being worked on.

  2. Scene 2

    Cutting the new key and gauging the depths

    On this cylinder type, the new key comes first, then the pins to match it. The locksmith cuts a fresh key from a blank on a code cutter or duplicator, choosing a combination that is not close to the old one, and reads each cut with a key gauge to find its depth on the manufacturer's scale. Bottom pins of the matching lengths are picked from a graded pin kit and dropped into the plug chamber by chamber, so that when the new key is inserted every pin top sits exactly at the shear line. A key cut from a clean blank and pins matched to it by gauge is what gives a rekeyed lock that crisp, new feel.

  3. Scene 3

    New keys, counted and tried in every door

    You finish the visit holding the only keys that work, and you know exactly how many there are. The locksmith cuts the agreed number from the fresh pinning rather than copying one from another, so each is as true as the first, and tries every one in every door it should open before handing them over. Count them, decide who in the household gets one, and put the spare somewhere you will remember. If a door was left on a separate key on purpose, that key is tagged so it does not get mixed into the house set. The whole set fits comfortably on one ring.

What shapes the quoteBox Grove Locksmith Pros

Several units in one building
A landlord rekeying a duplex, a triplex or a small apartment building, with each suite on its own key and a common entry shared, has more cylinders and a keying chart to build, and the quote grows accordingly.
Interior doors added to the plan
Bedroom, office or storage-room locks brought onto a key are lighter work than exterior deadbolts, but each is still a cylinder to pin and test, and the count includes them.
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.

Frequently asked questions

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.

What exactly does rekeying a lock change?

What changes depends on the cylinder. Many locks turn when a row of small bottom pins lines up at a precise level, set by the cuts on your key, and during a rekey the locksmith tips those pins out and loads a set that lines up with a different key, cut new for you; some residential cylinders instead reset a side-locking bar without removing any pins. From then on the new key operates the lock and older keys do not, and the hardware on the door stays as it was.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 19 in 100 homes · newer homes
  • About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.In newer developments the hardware is often the same finish and style from house to house. A locksmith can offer upgrades that match what is already there, so a stronger cylinder or a new lever set fits in without looking like an afterthought.
  • Single-detached houses make up about 56% of homes in Markham (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.
