🔐 Medeco vs GMS MX10 6704 Locks – What’s the Real Difference?

When it comes to key-controlled security systems, two popular options in Montreal are Medeco and GMS.

Both are designed to restrict key duplication, but they serve different needs, budgets, and applications.


🔑 Key Control – The REAL Reason People Choose These Locks

✔ Both Medeco and GMS keys CANNOT be duplicated at places like Home Hardware or standard locksmith shops

⚠ Duplication is ONLY possible if:

  • The locksmith carries the same keyway
  • AND is authorized to cut that key
  • AND the key is not stamped with a restricted company name

👉 This is critical for:

  • Apartment buildings
  • Commercial properties
  • Offices with employee turnover

🏱 Commercial Doors (Important Reality)

On commercial doors (especially glass aluminum doors with mortise locks):

⚠ The truth:

  • Most locks (including Medeco, Mul-T-Lock, etc.)
  • Can still be bypassed or forced open

👉 Why?
Because the door hardware and frame are often the weak point—not the cylinder.

✔ Even high-security cylinders don’t stop:

  • Pry attacks
  • Door flex
  • Latch failure

🔍 About Other High-Security Options

  • Mul-T-Lock
    • Strong key control
    • Still vulnerable in commercial door setups
  • Abloy
    • Unique rotating key system (360°)

👉 The goal is:
Delay + deter + control keys

For houses, we always recommend:

✔ Alarm system
✔ Security cameras
✔ Video doorbells (like Ring)
✔ Proper door reinforcement


⚠ Important Truth About Locks

  • Every lock can eventually be:
    • Drilled
    • Picked
    • Bypassed
