If your front door sees a lot of traffic, you rent out a basement suite, or you've had a lock picked or bumped before, a high-security cylinder like Abloy Protec2 or Medeco is worth it. If you're a homeowner on a quiet street with a solid Grade 1 or Grade 2 deadbolt and no history of break-in attempts, you probably don't need to spend the extra money yet. The real question isn't brand loyalty, it's whether your door and your situation actually need the protection these cylinders are built for.
What actually makes a cylinder "high security"
A standard pin tumbler cylinder, even a decent one, can usually be picked or bumped by someone who knows what they're doing, given enough time and privacy. High-security cylinders add features that make those attacks much harder: sidebar mechanisms, rotating discs or pins, hardened inserts that resist drilling, and keys that are much harder to duplicate without authorization.
Abloy's Protec2 line uses a rotating disc system instead of springs and pins, so bumping and raking don't work on it at all. Medeco uses angled, rotating pins that have to be lifted and turned at the same time, which defeats most standard pick techniques. Both are a different category from a $40 big-box deadbolt cylinder, and both are rated for serious pick and drill resistance under independent testing standards.
Abloy vs Medeco: what's actually different
Both brands solve the same problem but in different ways, and the choice usually comes down to your door hardware and budget rather than one being universally better.
- Abloy Protec2. No springs inside, which means it holds up better over years of heavy use and in cold, wet climates where moisture can affect spring tension. Keys are flat and don't have the cut pattern you'd recognize from a normal key.
- Medeco. Fits into more existing lock bodies and door prep without major hardware changes, which can mean a faster, less invasive install. The rotating pin technology has been around for decades and is well proven.
- Keyway control. Both brands use patented, restricted keyways. A locksmith or hardware store can't cut a blank copy without proof you're authorized on the system, which is the main reason people choose these over a standard cylinder in the first place.
If you're also deciding on the deadbolt body itself, not just the cylinder, our post on deadbolt grades explained covers the hardware side of that decision.
Who actually needs this upgrade
Not every door needs a restricted keyway cylinder. These are the situations where it earns its cost:
- Rental properties. If you've had tenants turn over and you're not sure every key got returned, a restricted keyway means nobody can walk into a hardware store and cut a spare without your sign-off.
- Shared entries. Townhomes, laneway houses, and basement suites with a common door get a lot of key handling over the years. High security cylinders keep track of who's authorized.
- Past break-in attempts. If your door's been picked, bumped, or you've found tool marks around the cylinder, this is the direct fix for that specific attack.
- Home businesses or storage. If you keep anything valuable at home (tools, equipment, cash) a cylinder upgrade is cheaper than most insurance deductibles.
If none of that applies and your main lock is a reasonably new Grade 2 deadbolt in good working order, your money is probably better spent elsewhere, like a proper strike plate or reinforced door frame.
What it costs and how long it takes
As a typical range, swapping a standard cylinder for an Abloy or Medeco high-security cylinder runs somewhere between $180 and $400 per lock, including the cylinder, labour, and a small set of cut keys. That range moves depending on whether your existing deadbolt body can accept the new cylinder directly or needs a full hardware swap, and whether you want the front door and a side or back door keyed alike on the same restricted system.
The install itself usually takes 20 to 40 minutes per door for a straightforward cylinder swap. If the door needs new hardware entirely, budget closer to an hour. One honest caveat: older doors, especially ones that have been painted over multiple times or have a warped frame, sometimes need extra fitting work, and that adds time and cost. A locksmith can usually tell you on the spot once they've looked at the door.
Key control is the part people forget to ask about
The lock itself is only half the value. The other half is who can get a copy of your key made. With a restricted keyway, you're put on a signature card with the manufacturer or an authorized dealer. Nobody else can order blanks or get keys cut on that system without being listed, which closes the loop that lets old keys, lost keys, or a contractor's spare become a problem years later.
This matters most for rentals and shared households. If you're thinking about securing a home that also has a safe for cash or documents, it's worth reading choosing a safe: fire rating, cash rating, and where to bolt it at the same time, since the two often get upgraded together.
When a standard lock is still the right call
If your door is solid, your household is small and stable, and you've never had an issue, a well-installed Grade 1 or Grade 2 deadbolt with a decent strike plate does the job. High-security cylinders solve a specific problem: unauthorized key copying and resistance to picking or bumping. If that's not a real risk for your door, spend the money on better hardware instead, or save it.
If you want an honest read on whether your door actually needs an Abloy or Medeco cylinder, have your current lock brand and model ready (it's usually stamped on the edge of the deadbolt or the cylinder face) along with how many keys are currently in circulation. Call Fast Locksmith Surrey and we'll look at the door itself, not just sell you the upgrade, and tell you straight if a standard lock will do.
Frequently asked questions
Can I put a Medeco or Abloy cylinder in my existing deadbolt?
Often yes, if your deadbolt body is a standard size and in good shape, since both brands make cylinders designed to drop into common hardware. Some older or off-brand deadbolts need the whole unit replaced to fit properly, which a locksmith can confirm by looking at the door.
Do I need to replace every lock in the house, or just the front door?
Most homes only need the main entry doors upgraded (front door, and back or side door if it's a regular entry point). Interior doors and less-used entries like a garage service door usually don't need the same level of protection.
What happens if I lose a restricted key?
You'll need to go through the authorized dealer or locksmith you registered with to get a replacement cut, since standard hardware stores can't duplicate it. Keep the signature card or account information somewhere safe, since you'll need it to prove you're on the system.
