🔐 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

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
