01 — The job

What this
call actually
includes.

Standard Kwikset or Schlage cylinders are picked in under a minute by anyone who watched a YouTube video. We swap the cylinder (not the whole lock) for a patented-keyway high-security core — Mul-T-Lock MT5+, Medeco M3, Abloy Protec2 — with hardened-steel drill inserts, anti-bump sliders and a signed authorization card that keeps duplicate keys out of the corner hardware store.

Included
  • · On-site assessment and firm quote before any work starts
  • · Parts stocked in the van — no second trip in most cases
  • · Full function test on every lock or door before we leave
  • · Two fresh keys cut on-site where the job produces keys
  • · Itemized invoice with HST, e-mailed same day
Never
  • · Fake "from $19" bait pricing
  • · Weekend or after-hours surcharge
  • · Drilling before we've tried picks and bump
  • · Push you toward a lock you don't need
  • · Cash-only or "call the office" invoicing

2

Flat price confirmed first

$29 flat service call, plus the parts and labour we quote you on the phone. No call-out fee added at the end, no charge for the quote.

3

Technician arrives on-site

A fully stocked mobile van across Toronto and the GTA in 15–30 minutes. Most jobs finish on-site the same visit.

03Why call us

Harbourline Locksmith vs.
a dealer or hardware store.

For high-security lock upgrade work, a hardware store sells the lock but doesn't fit it or rekey it. A dealer charges a premium and books days out. We handle the whole job in one visit, at your location.

06Before you call

Questions we
hear the most.

Will you damage my door?+

Under 5% of residential jobs end with a drilled cylinder. Picks, bump keys and bypass tools come first — drilling is the last resort, not the default.

Can you rekey to match my existing key?+

Yes on any standard 5- or 6-pin cylinder (Schlage, Kwikset, Weiser, Weslock). We match your existing key or hand you two fresh cut keys on-site.

How fast can you arrive for high-security lock upgrade?+

Immediate dispatch. Arrival window is 15–30 minutes from the call in most postal codes across Toronto, Mississauga, Brampton and the rest of the GTA.

How much does high-security lock upgrade cost?+

$29 flat service call covers the trip. Parts and labour are quoted on-site before any work starts, with a warranty on both. The number you hear on the phone is the number on the invoice.

Do you provide a real invoice with HST?+

Every job closes with an itemized invoice carrying our HST number, e-mailed before the technician leaves the site.

Long-form — high-security lock upgrade across Toronto & the GTA

The full scope of a high-security lock upgrade call — from dispatch to invoice

Houses, condos and triplexes across Toronto and the GTA — Downtown, North York, Scarborough, Etobicoke, East York, York, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Pickering, Ajax, Whitby and Oshawa. Residential locksmith work is the bread and butter of the van: deadbolts, knob sets, patio bars, mailbox cylinders, smart-lock retrofits, sliding-door pins and mortise-box repairs on century homes.

high-security lock upgrade is one of the most requested calls in this line. Every job is booked with a firm ETA on the phone, a firm price frame before the van moves, and closes with a warranty on labour and parts — no exceptions.

When to call for high-security lock upgrade

  • You just closed on the house and the previous owner had six copies floating around — rekey every exterior door in one visit.
  • A roommate left, a nanny finished up, a contractor walked with a spare — rekey rather than replace, save the cylinder cost.
  • Front-door cylinder is stiff, the key jams halfway, or the deadbolt binds against the strike — repair on the driveway.
  • Kwikset SmartKey cylinder is spinning or was bumped — upgrade to Schlage Grade 2 or Mul-T-Lock and move on.
  • Mail-slot cylinder or community-mailbox key is snapped — cut and re-key on-site the same visit.

How a high-security lock upgrade call runs

  1. 01Tech pulls up, walks the doors with you, confirms exactly which cylinders and hardware need attention.
  2. 02Firm quote before any work — parts and labour, one number, no call-out fee added at the door.
  3. 03Non-destructive first: picks, bump, bypass. Drilling is a last resort under 5% of residential jobs.
  4. 04Two fresh keys cut on-site on every job that produces keys — extra copies at cost.
  5. 05Full function test, walkthrough, itemized invoice with HST e-mailed before the van leaves.

Where high-security lock upgrade calls run daily

Detached in Riverdale, Leaside, Willowdale, The Kingsway, Forest Hill, Rosedale, Bloor West, Cabbagetown and Corso Italia. Condos in Liberty Village, CityPlace, King West, Yorkville, VMC and Square One. Townhouses in Regent Park, Corktown, Mount Pleasant Village, Pickering, Ajax and Whitby.

Pricing for high-security lock upgrade

$29 flat service call covers the trip. A single-cylinder rekey typically runs the service call plus one pin-kit fee. A full lock change is the service call plus the cylinder — Schlage Grade 2 is the most-requested; Mul-T-Lock and Medeco carry a premium but come with the patented-key restriction that eliminates unauthorized copies.

High-Security Lock Upgrade: mobile locksmith vs. dealer or hardware store

A hardware store sells you the lock — they don't come out and fit it, and they can't rekey it to match your existing key. A big-box installer books you three days out and charges a call-out fee on top of the quote. A neighbourhood mobile locksmith brings the whole shop to your driveway, fits and rekeys in one visit, and warranties both the labour and the parts.
