The difference between keying alike and master keys

'Keying alike' means that one single key operates all locks in a home or business. It is a master key of sorts and is useful for smaller business, however keying alike will not restrict access and anyone who is granted a key will be able to access all locks in a business that is keyed alike. On the other hand, where a master key opens all locks in a building, the subsidiary keys cut will only open a single lock in the building.

In a commercial, business or residential setting master keys and individual keys should always be restricted meaning that they cannot be copied by someone who is not authorised or identified as a legitimate key holder.

 

Benefits of Master Keys and Restricted Keys for business include:

• Ability to restrict access to sensitive areas of a business while allowing complete access to trusted employees or responsible individuals who need access to all areas.
• Individuals can access numerous areas by only using one key, meaning fewer keys needed. Less keys means less risk.
• Keys are easier to track and lessens the chance of duplicate keys being made without authorisation.
• Restricted keys are specially designed by one locksmith and copies can only be obtained through the locksmith who designed the key. This prevents unauthorised duplication.
• Restricted locks are more secure due to their patented design. This eliminates the possibility of a lock being accidentally clicked open with the incorrect key.

 

Tips to maintain a secure master key and restricted key system in your business:

• Don’t issue high level keys lightly. Make sure the consequences or losing or misplacing a key is clearly communicated as it means rekeying part or all of the system to stop the risk of the misplaced master key. If key-holders understand the costs of losing or misplacing keys they will take extra care.
• Always use a key register to track who has what keys at which times. Make sure that if circumstances change, keys are returned or when people no longer need them.
• Keep spare keys locked in a safe or off site wherever possible.
• A high position in a business should not necessarily mean master key access. Only allocate keys based on the job requirements of the key holder. A cleaner for example will need to access more rooms in a building than a department manager. The fewer master keys in circulation the better!
