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

The choice between rekeying and replacing comes down to the condition of the lock and what you want from it. A cylinder that turns smoothly, sits firmly in a solid deadbolt and matches the look of the door is worth keeping, and rekeying gives it a new key for a fraction of the effort of replacement. Replacement earns its place when the hardware is worn, low grade, damaged, a mismatched keyway that cannot join the house key, or when you want a keypad or a heavier deadbolt anyway. A locksmith looks at each door and tells you which one applies.

The call
The builder handed over your new home with a stack of identical keys, and you know the framing crew, the painters and the flooring installers all used a construction key during the build. The doors are brand new, but the key that opens them should be yours alone.

  1. Scene 1

    Reading the keyway on each lock

    Whether several doors can share one key depends on the cylinders, not the number of doors. Each lock has a keyway, the profile a key must match to enter the plug, and only cylinders with the same keyway can be pinned to the same key. The locksmith looks at the face of each cylinder and the profile of each existing key to sort the house into families. Most homes carry one or two of the common residential keyways, sometimes with an odd one on a side door or a padlock. Anything from a different family is noted so you can decide whether to swap that cylinder for a matching one and bring the door onto the house key.

  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

    A written note of what was done

    A short record closes the job: which doors were rekeyed, whether any cylinder was replaced, how many keys were issued and to whom, and any door that was deliberately kept on its own key. For a homeowner it is a line in the house file that answers the question, years from now, of which key opens what. For a landlord it is the handover to give the incoming tenant and to keep for the next turnover. For a property manager it is the start of a proper keying chart. It also makes any later work simpler, since the next locksmith can see what system the house is on.

What shapes the quoteBox Grove Locksmith Pros

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.
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.
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.

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.
