Everything You Need to Know About Master Key System
As Toronto locksmith experts, we are familiar with a wide selection of lock and key systems. One of which is the popular master key system.
A master key can operate a number of different locks while each of these locks can also be operated by its own key. A single key that can open many locks does not make this a master key system. It could just mean that the locks are keyed alike.
A good example of a master key system is an apartment building. While each tenant will have their own key that opens only their own door, there is also a key that opens all of the doors on that floor or in the entire building. The landlord or person in charge of maintenance will usually have the master key. You can also do the same in your home. For example, you can have one key that opens all of the doors with individual keys for each lock too. This way, you can provide your gardener with their own key that only gives them access to the appropriate parts of your property.
Different master key system
There are several types of keys in a master system and each of them allows a different level of access. These keys are as follows: Change Key: The key that will operate one lock and any locks that are identical. Master Key: The master key will operate several locks that are each operated by their own keys. Grand Master Key: This key is used to operate more than one master key systems. So, if you have more than one master key, you can use a grand master key to open all of the locks in each system. Great Grand Master Key: A step up from the grand master key. It can be used to open several grand master key systems as well as all the master key systems and all locks within these systems. At this point, the locks can become quite complex and it's worthwhile considering keeping things as simple as possible.
