When a lock change is worth doing
Moving in is the obvious trigger. Keys travel: previous owners, tenants, cleaners, contractors, the neighbour who fed the cat. A lock change on the exterior doors resets all of that in an afternoon. The other common reasons are a break-in or an attempt, a separation, a lost key that had an address tag on it, and a cylinder that has started to feel gritty.
Wear is worth taking seriously. A lock that has to be jiggled is telling you the pins or the key are worn, and that story usually ends with a key snapped off in the dark on a January night. Replacing it while it still works is far easier than dealing with it after it quits.
Keyed-alike sets and one key for the house
One key for the front, back and garage side door is the upgrade people appreciate most. Locks from the same manufacturer and keyway can be bought as keyed-alike sets, or matched to each other with the maker's own rekeying kit where the range supports it. Tell me how many doors and how many keys you want as part of the lock change and I will set the whole house up on one key.
Mixing brands is where this falls apart. Different makers use different keyways, so a deadbolt from one and a handleset from another will never share a key, whatever the packaging suggests. Keeping every opening on one line of hardware also means the finishes match and spare parts stay easy to find years later.
The parts that decide whether a lock lasts
Grades give you a rough guide. Grade 1 is commercial duty, Grade 2 is a solid residential choice, and Grade 3 is builder-basic. A deadbolt should throw a full bolt of about 25 mm (1 in) into the strike, and with the door closed that bolt should slide home under two fingers rather than a shove.
Strike plates are the weak link in almost every Toronto house I visit. Builders fasten them with short screws that bite only the jamb trim, and the jamb itself is thin softwood tacked to the framing. I swap those for screws long enough to reach the framing behind, usually around 75 mm (3 in), fit a box strike where the mortise allows, and add a reinforcement plate on doors that have already been forced.
What I check on every job:
- Backset, bore size and door thickness before any hardware is ordered
- Bolt throwing fully into the strike with the door closed
- Long screws into the framing at the strike and the top hinge
- Latch and strike aligned so the door needs no lifting or leaning
- Weather stripping compressing without fighting the latch
- Every key tried in every lock before I leave
Smart locks on doors that already exist
Smart locks are mechanical before they are clever. The motor that throws the bolt is small, so a door that binds will chew through batteries and eventually strip the drive. Alignment gets sorted first, then the lock goes on. Retrofit models that sit over your existing deadbolt on the inside keep your keys and your exterior look, which suits condo doors and rentals well.
Battery life, a backup key or keypad, and who holds the codes are the practical questions worth answering during a lock change. I set the account up in your name, add codes you can revoke later for cleaners or guests, and show you the manual override. Locks with a Wi-Fi bridge need a decent signal at the door, which is worth testing before you commit to one.
Where a locksmith is the right call
Lockouts are not my work. If you are standing outside your own door, call a locksmith, because that is a different skill set with different tools. Rekeying a cylinder to an existing key, high-security cylinders and master key systems also sit with a locksmith rather than with me, and I would rather send you straight there than fumble it.
Condo doors come with their own rules. A unit entry door onto a corridor is usually fire-rated and often falls under the corporation's hardware standard, so changing it can need approval and matching parts. Check with property management first, and I will fit whatever they allow, including door closers that have to be adjusted rather than removed.
