GMS MX Restricted Key System (MX10-6704)

Reliable Economic Security

What Is the GMS MX Restricted Key System (MX10-6704)?

The GMS MX Restricted Key System (MX10) is an economic, commercial‑grade pin tumbler locking system designed to offer basic key control and durability at a significantly lower cost than patented high‑security systems.


Security Level Explained

GMS MX10 locks are not classified as high-security, but they do offer:

  • Better durability than basic residential locks
  • Limited key availability compared to common retail keys
  • Compatibility with master key systems

They are ideal for budget‑conscious properties where controlled access is important but extreme security is not required.


Restricted Key Control & Duplication

The GMS MX system is considered a restricted key system, meaning key blanks are not commonly available to the public and are typically stocked only by locksmiths.

Keys:

  • Cannot be duplicated at hardware stores or key kiosks
  • Require a locksmith who carries GMS key blanks
  • Are intended to be duplicated only by the original locksmith

⚠️ No mechanical key system is 100% guaranteed. Some locksmiths with advanced equipment may bypass restrictions. A professional locksmith will always recommend returning to the original locksmith who issued the keys.


Key Features & Honest Facts

  • Cannot be duplicated at hardware stores or key kiosks
  • Uses a regular pin tumbler system
  • Available in 5-pin or 6-pin configurations
  • Key has the look and feel of a high-security thick key
  • Very strong, solid keys compared to standard residential keys

Cost Advantage:

  • Can cost up to 60% less than Medeco, Mul-T-Lock, Abloy, and CX5 locks
  • Key duplication savings are significant: in 2026, branded high-security keys cost $30–$40 per key, while GMS MX10 keys cost $12 each, and normal keys start at $4 each
  • Provides big savings for building owners
  • Ideal for buildings, landlords, offices, and businesses

🕵️‍♂️ If James Bond tried to pick it? Low chances. For an economic lock, it performs very well when properly installed and pinned.


Optional Pick-Resistance Upgrade

For clients who want extra protection, we can install protected heavy-duty security springs inside the cylinder.

  • Significantly increases pick resistance
  • Makes manipulation much harder
  • You may feel slight resistance when inserting or turning the key — this is normal and part of the added security

This upgrade improves security but still keeps costs far below patented high-security systems.


Master Keying Capabilities

GMS MX10 cylinders support:

  • Master key systems
  • Sub-master and grand master configurations
  • Re-keying without replacing the entire lock

Important Limitations

  • Does not include a security certificate
  • Not a patented or restricted keyway system
  • Key control depends on using the same locksmith

This lock is designed as an economic solution, not a maximum-security system.


Who Is GMS MX10 For?

GMS MX10 is the right choice if you want to:

  • Prevent employees, friends, or family members from easily duplicating keys
  • Avoid hardware-store copies
  • Maintain basic key control at low cost
  • Secure multi-unit buildings economically

If your main concern is extreme pick resistance or patented key control, this is not the right lock.

👉 If you are still worried that James Bond might show up and test your lock, choose Medeco instead.

⚠️ Key Duplication Notice – GMS MX10

GMS MX10 locks offer minimum to economic security.
Keys cannot be duplicated at hardware stores or kiosks and usually require a locksmith who carries GMS key blanks.

This is a controlled-key concept, similar to Medeco-style systems, where key duplication is intended to be done only by the original locksmith.
However, no mechanical key system is 100% guaranteed, and some locksmiths may be able to bypass restrictions.

A professional locksmith will always advise you to return to the locksmith who originally issued your keys.


⚠️ Avis important – duplication de clés GMS MX10

Les serrures GMS MX10 offrent une sécurité minimale à économique.
Les clés ne peuvent pas être copiées dans les quincailleries ou kiosques automatiques et nécessitent généralement un serrurier ayant des ébauches GMS.

Il s’agit d’un système de clés contrôlées, similaire aux systèmes de type Medeco, où la copie des clés devrait être faite uniquement par le serrurier d’origine.
Cependant, aucun système mécanique n’est garanti à 100 %, et certains serruriers peuvent contourner ces restrictions.

Un serrurier professionnel vous recommandera toujours de retourner chez le serrurier qui a fourni les clés à l’origine.
