The Ranking

Our top 5 locksmiths in Montreal

Montreal's housing runs from Plateau triplexes with outdoor stairs to downtown condo towers and Verdun duplexes, and each calls for something different at the lock. Triplex owners rekey after tenants move out, condo owners clone fobs, and small shops on Saint-Laurent and Henri-Bourassa need cylinders and hardware that match an older door. The trade is also crowded with call-centre operators that list an office suite or a house as an address and post the same page for every suburb, so we kept only companies with a street address in Montreal that we could match to a website, a phone number and a run of Google reviews. Quebec does regulate this work. Locksmith agencies need a licence from the Bureau de la sécurité privée, and you can look up a number at bsp.gouv.qc.ca. Ask for it before anyone touches your door, along with a firm price on the phone and photo identification when the technician arrives. Several shops here are weekday counters rather than 24 hour services, and each entry says so, so you can pick the one that fits your door and your schedule.

Methodology

How we chose the best locksmiths in Montreal

We searched Google Maps for locksmiths in Montreal on October 28, 2026, kept companies that were open, rated 4.5 or higher with at least 50 reviews, and checked each website and address. We rejected virtual offices, houses, doorway sites with one template per city, car-key-only companies and companies whose phone did not match Google. Companies are listed in the order Google showed them. No company paid for a place on this list. Fewer than ten companies passed, so the list has five.

Hiring

How to choose a locksmith in Montreal

  1. Get a firm price on the phone

    Ask for the full cost of the job, call-out included, before anyone drives over. A real shop can quote a lockout or a rekey in one call.

  2. Ask for the business name

    Write down the registered name and the address. Many listings are call centres that pass the job to whoever is closest.

  3. Check ID when they arrive

    The technician should match the company you called, with a marked vehicle or ID. A reputable locksmith will also ask for proof that you live there.

  4. Ask about the method

    Most lockouts can be opened without drilling. If the first move is to drill and replace the lock, ask why before you agree.

  5. Get a written invoice

    The invoice should name the company, the parts used and the labour. Keep it in case the new lock fails.

  6. Ask about the warranty

    New hardware usually carries a manufacturer warranty, and the work should carry the locksmith's own. Get both lengths in writing.

Questions to ask before hiring

0 of 8 asked

Red flags

  • A very low quote on the phone that grows once the door is open
  • No business name, only a generic 'locksmith service' answer
  • Drilling the lock as the first and only option
  • An unmarked car and no ID
  • Cash only, with no invoice

FAQ

Locksmith companies in Montreal FAQs

Do locksmiths need a licence in Montreal?

Yes. Quebec locksmith agencies need a licence from the Bureau de la sécurité privée. Ask the company for its number before booking and check it at bsp.gouv.qc.ca, along with a firm price on the phone and photo identification when the technician arrives.

How much does a locksmith cost in Montreal?

Prices vary by job, hour and lock type, so get a quote before work starts. Serrurier DM posts a base fee of $65 plus tax for travel and the first 30 minutes. Be wary of anyone who quotes only a low starting figure and will not explain the final bill.

Which Montreal locksmith is open on weekends?

None of the five shops on this list keeps weekend counter hours according to Google. Serrupro advertises a shared 24 hour line and some sites claim round-the-clock service, so call first and ask for an arrival time and the full price before agreeing to a callout.
