Should I repair my door lock or replace it entirely?

The client's name has been changed.

Let's call the client Mikhail. The lock began to jam, and Mikhail received two completely different pieces of advice:

“Just change.”

and

“Everything can be fixed.”

Both answers may be correct, depending on the state of the mechanism.

When renovation makes sense

For example:

• local fault;
• necessary parts available;
• the mechanism is generally in good condition;
• the problem is caused by adjustment;
• A separate cylinder can be replaced.

Why the cylinder lock sometimes does not need to be replaced entirely

If the problem is in the replacement cylinder, the main body may remain. This often solves the problem:

• cheaper;
• faster;
• without altering the door.

When replacement makes more sense

If: *damaged;

• the mechanism is very worn;
• repairs have already been carried out several times;
• details are practically inaccessible;
• the existing system no longer meets the owner's requirements.

And after losing the key?

The mechanism itself may be fully operational. But if you need to terminate the validity of old keys, it is the access system that changes. In some designs, a new cylinder is sufficient for this.

Why a non-standard old lock is a special case

Sometimes the old mechanism has dimensions that make it difficult to fit a modern replacement without altering the door. Then repairing an existing product may be more economically logical.
