Patent-Protected Key Systems
Pick-, drill- and bump-resistant cylinders with keys that can’t be copied at the hardware store. Cut, pinned and registered in-shop.
Fast Locksmith Vancouver supplies and installs high-security cylinders and restricted-keyway systems for homes, strata buildings, offices, and retail, with Mul-T-Lock as the line we fit most often. Pick-, drill-, and bump-resistant hardware, plus real key control so nobody cuts a spare behind your back.
A good lock does two jobs: it resists attack at the door, and it stops unauthorized keys existing in the first place. Most hardware-store deadbolts do neither particularly well.
A high-security lock isn't just a heavier deadbolt. It's a cylinder engineered against the three ways locks actually get beaten in the field (picking, drilling, and bumping), combined with a restricted keyway, so the key itself can't be duplicated at a kiosk or a hardware counter. Fast Locksmith Vancouver installs that class of hardware across the city, and Mul-T-Lock is the line we fit most often.
The people who call us about it usually fall into two camps. Homeowners who've just had a break-in attempt on a back door in Hastings-Sunrise or Mount Pleasant and realised the original builder-grade cylinder gave up in seconds. And property managers, strata councils, and business owners who've worked out that the real problem isn't the lock at all: they have no idea how many copies of the key are out there.
The term gets used loosely in retail. In practice, four properties separate a genuine high-security cylinder from a heavy-looking one.
The key profile is a controlled design. The blanks aren't sold into the open market, so a hardware store or a mall kiosk physically cannot cut a copy. They don't stock the blank, and the profile is protected. This is the property that matters most to landlords, employers, and strata corporations, and it's covered in detail further down.
Standard pin-tumbler cylinders can be picked or raked open by someone who has practised. High-security cylinders add defences: security pins that bind and mislead a pick, tighter machining tolerances, sidebars or telescopic pin designs that require the correct key geometry rather than just the correct pin heights. The realistic effect is that a casual attack fails and a skilled one takes long enough to be noticed.
Drilling out a cylinder is the fast, noisy, low-skill attack. High-security cylinders are built with hardened steel inserts and anti-drill pins placed where a bit would have to pass, turning a 30-second job into one most people abandon.
Bumping uses a specially cut key and a tap to jolt a standard cylinder's pins into the shear line. It works alarmingly well on ordinary hardware and needs almost no skill. High-security designs defeat it structurally, because a bump key has no way to move the extra locking elements.
High-security work is quoted per door, because the cost depends on what hardware is already there and whether the cylinder can be swapped into it. The ranges below are typical for Vancouver jobs. Your actual quote comes after we've looked at the doors.
| Service | Typical range |
|---|---|
| High-security deadbolt supply & install | $180 – $350 |
| Restricted keyway changeover | $200 – $500 |
| Cylinder re-pinning for existing hardware | $55 – $120 / cylinder |
| Restricted key blanks (per key, ongoing) | $18 – $45 / key |
| High-security / restricted key cut (with authorization) | $30 – $70 |
| Security strike plate reposition or upgrade | $75 – $140 |
| Frame & jamb repair (break-in damage) | $150 – $350 |
| Master key system (up to 10 doors) | $400 – $900 |
Ranges are typical estimates, not quotes, and they cover parts and labour for a standard installation. Heritage doors with non-standard prep, heavy commercial frames, and multi-point systems sit at the higher end. We'll walk you through it before any work starts. No surprise fees.
We look at the doors, not just the locks. Which entrances matter, what hardware is fitted now, how the frames are holding up, and who currently holds a key. That's what a sensible recommendation is built on.
We pick the cylinder and the restricted profile that fits the building and the budget, confirm how many keys you need, and quote it in writing before ordering anything.
Cylinders go in, strike plates and frames are brought up to match, keys are issued against a sign-off sheet, and you leave with a documented record of who holds what.
Mul-T-Lock is our lead line for high-security work in Vancouver, and it's what we quote by default unless there's a reason not to. Its telescopic pin-tumbler design gives it genuine pick and bump resistance, the restricted profiles give you proper key control, and the range covers what people here actually need: residential deadbolts, commercial mortise and rim cylinders, padlocks, and retrofit cylinders that drop into a lot of existing hardware.
It isn't the only option. Medeco, Abloy, Kaba, and the commercial Schlage lines all make high-security products, and each has situations where it's the better answer: a specific door prep, an existing system you're extending, or a keyway you're already committed to. We carry commercial-grade hardware on the truck, including Schlage, Medeco, and Mul-T-Lock cylinders, and we'll source others on request for a scheduled job. If you tell us a brand, we'll tell you honestly whether it's right for your doors. We recommend what fits the project, not whatever has the highest margin for us.
This is the part that sells the system, and it's the part most people have never had explained to them.
An ordinary house or office key is a commodity. The blank is sold everywhere, the machine is on the wall at the back of the shop, and copying it takes ninety seconds and costs a few dollars. Nobody asks who you are. That means the honest answer to "how many keys exist for this door?" is almost always: we don't know. A tenant who moved out two years ago, a contractor who had access for a renovation, a former employee who was supposed to hand their key back. Any of them could have cut a spare, and nothing in the lock would ever show it.
A restricted keyway removes that uncertainty. The blank isn't available at retail, so an unauthorized copy can't quietly come into existence. When you need another key, it comes from us: sourced through the manufacturer's controlled channel, cut against your documented authorization, and recorded by serial number. For a restricted or patented key we verify you're the authorized holder first: proof of address, tenancy, or a property manager's written OK.
The practical result is that when a key goes missing, you actually know what you're dealing with. One key is out, it can't be duplicated, and you can decide whether to re-pin that cylinder or leave it. You aren't re-keying an entire building on the assumption that copies exist, because they can't.
Fitting a high-security cylinder to a door that a shoulder opens is money badly spent. In most forced entries around Vancouver the cylinder is never touched. The frame splits at the strike plate, where a short screw is holding into soft trim rather than into the stud behind it. The lock is fine. The wood isn't.
So we treat the lock and the door as one job. That means a security strike plate with long anchors driven into the framing, hinge screws replaced with long-screw reinforcement, and the jamb repaired or reinforced where it has already been stressed. On a lot of the older housing stock here (wood-frame homes in Dunbar and Kerrisdale, pre-war bungalows in Hastings-Sunrise and Mount Pleasant), this makes a bigger difference to real-world resistance than the cylinder does.
If you've already been broken into, that work is usually urgent and comes first: see door repair for frame and jamb repair after forced entry. We can do the repair and the high-security upgrade in the same visit, which is normally the sensible way to handle it: the door is open, the hardware is off, and you only pay one call-out.
Retail shops and restaurants carry cash, stock, and staff turnover all at once, and a back-of-house door onto a lane is the weak point in most of them. Restricted keys mean a departing staff member can't have left a copy behind, and a hardened back door means the lane entrance stops being the easy option.
Warehouses and light industrial units fill the working corridors along East Hastings and out past Commercial Drive and Clark, alongside trade counters and shops where multiple crews, drivers, and contractors need access at different hours. Restricted keys, often master keyed, are how you give people access without losing track of it.
In strata buildings, common doors, amenity rooms, storage cages, and bike rooms all end up with keys in circulation that nobody has a list for. A restricted system plus a documented key register is how a council gets that back under control, and it's the usual reason a council calls us in the first place. Strata work often pairs with a master key system.
In offices, server rooms, records storage, and executive suites genuinely shouldn't be on the same key as the front door. High-security cylinders on the doors that matter, standard hardware elsewhere, and a hierarchy over the top of it is a normal, affordable setup. See commercial locksmith for the wider business side of this.
For most homes and condos the right answer is a high-security cylinder on the doors that are actually vulnerable (front, back, and the side door nobody thinks about), with the frames reinforced to match. It's a far better use of money than putting an expensive lock on every door in the house.
