- 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.

In plain words
When people say upgrade they usually mean a heavier lock, and there is a real scale behind that word. Builders hardware in North America is graded to ANSI/BHMA standards, with Grade 1 the highest and Grade 3 the lightest, and residential products carry a separate label scoring security, durability and finish. A higher grade certifies stronger performance on the standard's own tests, and moving up often brings a longer hardened bolt, a sturdier housing, pins that resist picking and a strike built to anchor into the framing, though the exact features depend on the model. The locksmith explains which grade fits which door.

How the visit goes
Scene 1
Who is asking for the change
The first check is about the person, not the door. An owner can change any lock on their home. A tenant who wants new hardware on the unit door needs the landlord's agreement, and a landlord who changes a lock while a tenant lives there hands over new keys. The locksmith asks which situation applies and, where paperwork helps, looks at identification, a deed, a lease or a property-management note. It takes a minute and it means the new lock goes on with everyone who has a stake in the door knowing about it, which is exactly how a lock should start its working life.
Scene 2
Taking the old hardware off without harm
Removal is done with the same care as fitting. Interior trim screws come out first, then the interior rose or thumb-turn, and the exterior housing lifts away with its tailpiece. The latch or bolt slides out of the edge bore once its two faceplate screws are released, and the old strike comes off the jamb. Painted-over screws are scored free rather than forced, seized screws are eased with a hand driver of the right size, and a stripped head is drilled out only as a last step. The bore and edge mortise are then cleaned of paint build-up and debris so the new parts seat properly.
Scene 3
Simple habits that keep new hardware new
New locks ask very little. Once or twice a year, or at whatever interval the lock maker specifies, a puff of the lubricant that maker calls for in the keyway and a few turns of the key keep the pins moving freely, since the wrong product for that cylinder gathers grit instead of helping it. In winter, wipe salt spray off the exterior hardware when it appears, since salt is the finish's main enemy here. Each spring and fall, check that the hinge and strike screws are snug, because wood doors move with humidity and a dropped door makes a good lock feel worn. A key that starts to need coaxing is an early word from the cylinder.

What shapes the quoteBox Grove Locksmith Pros
- 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.
- Strike reinforcement and jamb repair
- A reinforced strike with long screws is a modest addition; repairing a jamb split from a forced entry, or fitting a strike box into a frame that has never had one, adds labour and materials.
- Door material and thickness
- Wood, steel and fibreglass doors are drilled and fitted differently, and a door thicker than the standard 45 millimetres needs extension parts, so the door itself shapes part of the quote.

Frequently asked questions
Can a lever replace a knob on the same door?
Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set.
Can every door in the house work from one key?
Yes, provided the cylinders share a compatible keyway, which the locksmith checks when choosing hardware. New cylinders are pinned on site to a single new key and any existing locks worth keeping are repinned to match. Front, back, side and garage doors commonly end up on one key, and a shed or gate padlock can join them. You then decide how many copies exist and who holds each.
What does a higher grade of lock actually give me?
Grades follow ANSI/BHMA standards, with Grade 1 the highest and Grade 3 the lightest, and residential hardware carries a separate label that scores security, durability and finish. The grade reports how the lock performed on the standard's own operational, strength and security tests; a higher grade often comes with a longer bolt, a sturdier housing, pins that resist picking and a strike built to anchor into the framing, but those features are worth confirming on the specific model rather than assumed from the grade alone.

2021 census: what it means at the door
Every square is one home in a hundred.
- 19 in 100 homes · newer homes
- 56 in 100 homes · mixed housing
- 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.
