High security locks etobicoke businesses choose depend almost entirely on what they’re protecting and how much they’re willing to invest. Mul-T-Lock, Medeco, and ASSA Abloy each suit different security needs, and choosing the right option depends on the property and hardware requirements.
- Mul-T-Lock MT5+ may suit retrofit scenarios where pick resistant security is needed without replacing the entire door frame. Pricing is provided before work starts.
- Medeco M3 is an option for high traffic commercial properties where rekeying flexibility and master key complexity matter.
- ASSA Abloy may be considered where electronic access control, alarm systems, or multi building security are required.
- Basic deadbolts and high security locks can offer different levels of protection.
Side-by-Side Comparison: The Core Specs
Before diving into real-world use cases, here’s exactly how these three match up on the attributes that matter most for Etobicoke commercial and residential applications.
| Attribute | Mul-T-Lock MT5+ | Medeco M3 | ASSA Abloy |
|---|---|---|---|
| Installation Cost (per cylinder) | Priced per job | ||
| Pick Resistance | Excellent (rotating pin stacks) | Excellent (angular pin cuts) | Good,Very Good (depends on model tier) |
| Drill Resistance | Very Good (hardened core) | Excellent (hardened boron-steel pins) | Excellent (hardened core, rebar options) |
| Rekeying Flexibility | Good (standard pin depths) | Excellent (8 pin depths available) | Excellent (multiple keyway options) |
| Weather Resistance (Great Lakes/winter) | Very Good | Very Good | Excellent (rated for coastal & de-icing salt) |
| Smart Lock Integration | Limited (mechanical only) | Limited (mechanical only) | Excellent (connects to Schlage Encode, Yale Assure) |
| Warranty | Lifetime (defects) | Lifetime (defects) | Lifetime (defects) |
Mul-T-Lock MT5+: When Pick Resistance Is Your Priority
The MT5+ may suit properties where the concern is opportunistic entry using basic lockpicks rather than drilling equipment. The rotating pin stacks inside the cylinder rotate as you insert the key, making the lock feel slightly different each time and helping resist standard picking techniques.
Rekeying is available for commercial properties after staff changes.
Strength: If your building has seen an attempted break-in using a pick set, or if your insurance underwriter flagged lock quality as a liability, MT5+ closes that gap fast. The hardened core resists drilling longer than standard cylinders, and the rotating pins mean a pick-resistant lock without the expense of a complete electronic system.
Weakness: It’s entirely mechanical. If you later decide you want keypad entry, remote unlock capability, or integration with a building wide access control system, you may need a different cylinder. MT5+ drilling resistance may differ from other lock options.
Cost: Installation and rekeying are priced per job. You get the exact price before any work starts.
Medeco M3: The Master-Key Specialist
Medeco may suit buildings with multiple doors and intricate master key relationships. The angular pin cuts and 8 depth pin stacks can support a hierarchy: a master key that opens all doors, sub masters for different floors or departments, and individual keys that work only on specific locks.
This can matter for property managers running multiple buildings. Tenants, maintenance staff, and emergency responders may need different levels of access without separate key systems. Medeco can encode that logic into the lock itself without software, batteries, or cloud dependency.
Strength: The hardened boron steel pins resist drilling exceptionally well. A professional locksmith can rekey an M3 cylinder faster than an MT5+ because the pin stack doesn’t rotate: you simply swap the pins, and the lock is ready. If your building has high staff turnover or frequent lock rekey demands, M3 may be easier to maintain long term.
Weakness: The angular pin cuts, while designed to resist picking, are also more complex to cut. If you lose your key and the original Medeco master code isn’t documented, a standard locksmith cannot cut a replacement key without the factory code. You may need to contact Medeco or a mobile locksmith with the appropriate templates.
Cost: Installation, master key systems, rekeying, and replacement keys are priced per job. You get the exact price before any work starts.
ASSA Abloy: Integration and Scalability
ASSA Abloy owns the intersection of mechanical locks and networked security. Their cylinders work standalone like any other high-security lock, but they also integrate with electronic access-control systems, alarm manufacturers, and smart-lock hardware like Schlage Encode and Yale Assure. If your Etobicoke business already uses a Honeywell alarm system or a Genetec access-control platform, ASSA Abloy cylinders speak the same language.
This brand is also purpose-built for the Great Lakes climate. Lakeshore properties face salt spray, freeze-thaw cycles, and humidity that corrode standard cylinders. ASSA Abloy’s stainless-steel components and specialized coatings resist that wear far better than competitors.
Strength: Future-proof investment. You install ASSA Abloy today, and in two years when you want to add keypad access or connect your building to a mobile unlock app, the cylinder doesn’t need replacement. The ecosystem also means a locksmith in New Toronto or Mimico can service your lock faster because the parts and documentation are standard industry-wide.
Weakness: Electronic integration can add complexity and affect the scope of a project. For a small business with a single exterior door, it may be more than is needed.
Cost: Mechanical cylinders, master key systems, and electronic access control are priced per job. You get the exact price before any work starts.
When to Choose Which Lock
- You need pick resistant security on a tight budget for a single door retrofit, small condo, or storefront in Islington Village or Long Branch.
- Your threat model is amateur forced entry or picking attempts, rather than professional drilling or manipulation.
- You have no plans to integrate electronic access control or smart locks in the foreseeable future.
- You want to upgrade from a basic deadbolt without replacing the entire door frame or hardware.
- You manage multiple doors across one or more buildings and need a sophisticated master-key system (3+ doors with different access levels).
- Your staff experiences frequent turnover and you need fast, low-cost rekeying without ordering new keys from the manufacturer.
- Drill resistance is as important as pick resistance (high-threat retail or office in Mississauga or The Queensway).
- You want a mechanical lock with zero dependency on batteries or internet connectivity.
- Your business runs or plans to run an access-control system (keypad, badge reader, mobile unlock) alongside mechanical locks.
- Your property sits in a corrosive environment (Lakeshore buildings exposed to salt spray, wet basements in Mimico).
- You want a single vendor solution that handles both mechanical cylinders and electronic components, reducing vendor fragmentation.
- You’re willing to pay premium upfront to avoid replacement costs later when you upgrade to smart locks or integrated building management.
Our Verdict
There is no single “best” high-security lock across all scenarios. What we see repeatedly, though, is this:
For single residential units or small retail spaces in Etobicoke or New Toronto: Mul-T-Lock MT5+ may help bridge the gap between a basic deadbolt and more extensive ASSA Abloy hardware. It offers pick resistance and straightforward installation. Pricing is confirmed before work starts. If you later choose to integrate smart locks, your hardware needs can be reassessed.
For multi door commercial spaces or property manager scenarios: Medeco M3 may offer operational simplicity. The 8 pin depth system can support different access levels without rekeying every door when someone leaves. It may suit restaurants, medical offices, or property management companies that need regular rekeying. Drill resistance and lock quality may also be relevant when reviewing security requirements.
For buildings where security is layered, including access control, alarm integration, and networked monitoring: ASSA Abloy may be considered. It can involve a broader scope than mechanical only locks. For properties using alarm or access control systems, lock hardware should be selected to fit the overall security plan and future needs.
Whatever lock you choose, consider rekeying after a tenant leaves. Previous tenants’ keys may still work, and regular maintenance can help keep lock hardware in good condition.
Frequently Asked Questions
Can I upgrade from a Schlage or Kwikset to Mul-T-Lock or Medeco without replacing my door?
In many cases, standard mortise or cylinder bore sizes can accommodate an MT5+, M3, or ASSA Abloy cylinder without changing the door frame. If your door is an older Kwikset unit or a non standard size, a professional locksmith can assess fitment on site to help avoid ordering the wrong lock.
