Markham blends mature detached blocks, basement secondary suites, and newer town rows. Rekeying is still the right move when cylinders are healthy but people are not. Bundle the doors you actually control - then call with counts and brands for a straight quote.

These pages match the same quote-before-dispatch rules described here — useful when you want the short version for your exact municipality and service.
At a glance
General guidance only — not a quote or guarantee. Call (647) 874-2137 for a no-obligation estimate and a live ETA for your address and exact lock or key situation.
1. Separate legal units from the main house bundle
If the basement has its own metered address or separate lease, it may need its own pinning plan. Mixing keys across legal units without paperwork is a liability - tell dispatch if two households share one porch.
2. Garage passage and side doors belong in the same conversation
Most break-ins ignore the fancy front door. Include passage, side, and keyed patio doors when you want one key life. Sheds only if they matter to your security model.
3. Builder hardware versus upgrades
Some newer stock still ships with light-duty knobs. If you want Grade 1 deadbolts while we are on site, say so - rekey plus upgrade is a different parts line than pins alone.
Our mobile locksmiths serve the entire GTA. Call (647) 874-2137 for current availability.
4. Keyed-alike without mystery cylinders
Photos of faceplates help us bring the right pinning kits. Mixed brands on one key is not always possible - we confirm before we promise one key for every door.
5. York Region timing honesty
Lunch crunch on Highway 7 and school-bell traffic on major collectors can shift windows. Book mornings when you need a tight finish; afternoons are fine when the diary is flexible. Cylinder totals on the first call beat three follow-up texts.
