Restricted Key Systems Plantation

What Is a Restricted Key System?

A lock system where the key blanks are patented and physically unavailable without authorization. Standard keys can be duplicated at any hardware store kiosk for $3. Restricted keys require your authorization card at an authorized dealer like Triton Locksmith Plantation. The blanks simply are not available anywhere else, not at Home Depot, not at MinuteKey kiosks, not at unauthorized locksmiths, and not online.

This matters for businesses because employee key copies are a major security leak. According to the Associated Locksmiths of America (ALOA), unauthorized key duplication is a factor in over 40% of commercial property theft incidents attributed to insiders. Restricted keys close that gap completely.

How Are Restricted Keys Different from "Do Not Duplicate" Keys?

"Do Not Duplicate" is a request. Restricted is a physical barrier. A "DND" stamp on a key is legally non-binding. Any hardware store clerk can ignore it and cut the key anyway. Most automated kiosk machines don't even check for the stamp. It provides zero actual key control.

A restricted key uses a patented keyway profile that is physically different from any standard blank. Even if someone takes it to a locksmith, they cannot duplicate it because the blank doesn't exist outside the authorized dealer network. That is the fundamental difference: one is a polite sign, the other is a physical impossibility.

Which Restricted Key Brands Does Triton Locksmith Plantation Carry?

• Medeco M3/X4 ($200-$350/door): Rotating pin mechanism with sidebar. Patent through 2032. The most popular restricted key system in Plantation and surrounding cities commercial buildings. Works with master key systems.
• Mul-T-Lock Interactive+ ($250-$400/door): Telescoping pin-in-pin design with a floating element. Patent through 2030. Highest pick resistance of the three brands.
• Abloy Protec2 ($300-$600/door): Disc detainer mechanism (no pins or springs). Patent through 2034. Zero corrosion issues, ideal for coastal Plantation and surrounding cities properties.

Triton Locksmith Plantation is an authorized dealer for all three brands, meaning we can cut restricted keys on-site and order additional blanks as needed. You do not need to go through a third party.

How Does the Authorization Card Work?

When Triton Locksmith Plantation installs your restricted key system, you receive an authorization card. This card has a unique code tied to your keyway. When you need additional keys, you present (or reference) this card to an authorized dealer. Without it, no one can order or cut keys for your system. You control who has keys and how many exist.

Many businesses keep the authorization card in a safe or with the CEO/owner. Some property managers keep it in their main office. The important thing is that it stays with the person responsible for security decisions. If the card is lost, Triton Locksmith Plantation can reissue it through the manufacturer with proof of ownership.

Who Needs Restricted Key Systems?

Any business where unauthorized key duplication creates a security risk. Medical offices storing patient records under HIPAA, financial firms holding sensitive data, law offices with confidential files, property management companies with master keys to hundreds of units, government facilities, and any business with high-value inventory. If you currently rely on "Do Not Duplicate" stamps, you have no real key control.

Can Restricted Keys Work with a Master Key System?

Yes. All three brands support master key hierarchies with restricted blanks. Each tenant or employee gets a unique restricted key that opens only their door. The master key (also restricted) opens everything. Both the individual keys and the master key are uncopyable without authorization. This is the most secure commercial key system available.
