Frequently Asked Questions - Master Key Systems Dormakaba

What is a master key system?

A master key system allows a single key (master key) to open multiple locks, while each individual lock has its own unique change key. It provides hierarchical access control, e.g. a building master key opens all doors, a floor master key opens only those on a floor.

How do I order additional keys for my Dormakaba master key system?

Additional keys must be ordered from a Dormakaba authorized dealer or locksmith. You will need the key number or security card. Key duplication is restricted to prevent unauthorized copies.

Can I rekey my Dormakaba master key system myself?

Rekeying (changing the pin combination) requires specialized tools and knowledge. It is recommended to have a licensed locksmith perform rekeying to maintain security and master key hierarchy.

What maintenance is required for the system?

Periodically lubricate the cylinder with graphite powder (not oil). Clean the keyway with a soft brush to remove debris. Avoid water or chemical cleaners. If the key becomes hard to turn, consult a locksmith.

Are Dormakaba master key systems compatible with other brands?

No, Dormakaba uses patented keyways and proprietary pin sizes. Cylinders and keys are not interchangeable with other brands. Always use Dormakaba genuine parts.

How secure are these systems?

Dormakaba master key systems include features like anti-drill pins, hardened steel inserts, and patented key control. They meet security standards such as EN 1303 and ANSI/BHMA Grade 1, providing high resistance to picking and drilling.

What is a security card?

A security card is provided with each master key system. It contains the key code and must be presented to order duplicate keys or additional cylinders. Keep it in a safe place.

Can I integrate this system with an electronic access control?

Yes, Dormakaba offers electronic cylinders and hybrid solutions that combine mechanical master keying with electronic access control, such as keypads or RFID readers. Contact Dormakaba for compatible options.

What should I do if a key breaks in the lock?

Do not force it. Use a lubricant like graphite and try to extract with tweezers or a broken key extractor. If unsuccessful, call a locksmith. Avoid drilling the cylinder unless necessary.

How long does a Dormakaba master key system typically last?

With proper maintenance, the mechanical parts can last decades. Springs may weaken over time but are replaceable. The key finish may wear, but functionality remains. The system is designed for long-term use.
