Why a lock can be difficult to open in an emergency, but inconvenient in everyday life

The client's name has been changed.

Let's call the client Matthias. When choosing a new system, he focused almost exclusively on the maximum complexity of the mechanism. Later it turned out that everyday use was not as convenient as expected.

Questions arose: *service is not available everywhere.

• difficult to make additional keys;
• not all family members are accustomed to the system;

A thought arose:

“Or maybe, when choosing, I looked only at protection and forgot about normal operation?”

It really is possible.

Protection is only one criterion

The materials provided provide examples of complex disk and lever mechanisms, where design features significantly increase the complexity of working with the lock.

But for the owner of the door, the following are also important:

• convenience;
• availability of keys;
• service;
• maintainability;
• ability to change access;
• cost of service.

The system must match the users

For an apartment where one person lives, the requirements are the same. For families with children - others. For the office - the third. For example, you might need to be able to:

• issue separate keys;
• quickly change access;
• control copying;
• arrange Master Key.

Why "most difficult" does not always mean "most suitable"

If the user experiences inconvenience every day, the system ceases to be a good solution for this particular object. The choice must consider a balance between: safety + convenience + service + budget.

What is useful to discuss before purchasing

Tell the master:

• how many people use the door;
• who will be given the keys;
• are additional copies needed?
• will the premises be rented out;
• is a Master Key needed?
• how important is control over the production of duplicates.
