Lock Replacement & Upgrade

Someone tried the back door while you were away. The jamb is splintered around the strike, the bolt is bent, and the knob turns with a grinding feel.

In plain words

A replacement lock has to fit holes that already exist, and that is where the visit begins. The locksmith measures the backset, the distance from the door edge to the centre of the bore, which on most doors is 60 or 70 millimetres, checks the cross-bore diameter and edge-bore size, notes door thickness and handing, and looks at the strike cut-out. Most residential hardware is made to these standard preparations, so the new lock usually drops into place with no new drilling. Where a mortise lock or a thick door departs from the norm, filler plates, extension kits or a careful new bore bring the door up to standard.

Sound familiar?Heritage Park

The call
Three teenagers, a dog walker, a cleaner and one house key that keeps going missing. You are tired of cutting copies and would rather give each person a code you can switch off, with a proper deadbolt behind it.

  1. Scene 1

    Measuring the existing preparation

    Before any product is chosen the door is measured. Backset first, the distance from the door edge to the centre of the bore, which on most doors here is 60 or 70 millimetres. Then the cross-bore diameter, the edge-bore size, the shape of the latch faceplate, the door thickness and the handing. The strike cut-out and any glass, trim or storm door that limits where hardware can sit are noted too. These few numbers decide which locks will drop straight into the door and which would need a filler plate, an extension kit or fresh drilling, so they are written down before the catalogue is opened.

  2. Scene 2

    Keying the new locks to one key

    New cylinders arrive on random keys, so the locksmith pins them alike on site when you want one key for the house. Each cylinder is removed, the plug slid out on a follower so the springs stay put, and the bottom pins replaced to match a single new key. Existing cylinders that are staying are repinned the same way. Every key is then cut from the new combination, tried in every lock it should open, and any that drag are recut rather than handed over. The result is one key for the front, back and garage doors, and a clear count of how many exist.

  3. Scene 3

    An opening that is stronger, not just newer

    Where the strike was reinforced, the improvement is mostly invisible and worth understanding. Long screws now tie the strike through the jamb into the framing, the pocket has been cut to take the whole bolt, and any split wood has been repaired. Together these make the frame the equal of the deadbolt, which is the part most break-ins defeat. The locksmith points out what changed so you can check it yourself: a bolt that seats fully with the door closed and a strike that stays put under a firm push. A twice-yearly look at those screws keeps it that way.

What shapes the quoteHeritage Park Locksmith Specialists

Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
Number of doors
One back door is a small visit; the front, back, side, garage man-door and patio slider together are a longer one, though several doors done at once share the travel and setup.
Changes to the door preparation
Adjusting a strike mortise is minor; boring a new hole for a deadbolt, fitting a filler plate over an old mortise pocket or adapting a thick door with extension kits is quoted as its own item.

You asked, we answered

Should I rekey my locks or replace them?

Rekey when the hardware is sound and the problem is the key: a lost copy, a move, or too many keys for one house. Replace when the mechanism itself is worn, the housing or bolt is damaged, the grade was never suitable for the entrance, or you want a different function, finish or a keypad. Many visits do both, keeping good locks and rekeying them while replacing the tired ones, all to one key.

Can you replace the lock on a sliding patio door or French doors?

Yes. Sliding doors take a replacement mortise hook lock sized to the rail, often with a keyed exterior, and benefit from a secondary foot bolt or a pin through the frames. French doors are secured by treating the inactive leaf properly with flush bolts into the head and sill, then fitting a deadbolt to the active leaf with a strike into that reinforced edge. Both are routine parts of a residential upgrade.

Can you match the new lock to my other door hardware?

Yes. Manufacturers make deadbolts, handlesets, knobs and levers in matching finishes and styles, so a replacement deadbolt can sit above your existing handle without looking like an afterthought. Bring or photograph the hardware you want to match, including the interior side, and note whether it is a warm brass, a satin nickel, an oil-rubbed bronze or a matte black. Where an exact match is not made, the locksmith suggests the closest family.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 49 in 100 homes · mixed ages
  • About 49% of homes in Kitchener were built in 1980 or earlier, according to the 2021 Census.Mixed housing ages mean the advice changes door by door. An older solid-wood entry may want a strike reinforced; a newer steel door may want its short strike screws swapped. The locksmith looks at the door in front of him rather than assuming.
  • Single-detached houses make up about 48% of homes in Kitchener (2021 Census).Where houses and attached homes share an area, lockouts are as varied as the doors. A porch, a hallway or a shared vestibule each calls for a slightly different approach, and a locksmith used to all three arrives ready for whichever it is.
