Why after several repairs of one lock, a replacement may become cheaper

The client's name has been changed.

Let's call the client Sergei. Over the course of several years, the same mechanism was repaired three times. Each individual repair cost significantly less than a new lock.

That's why Sergei chose repairs every time. After another malfunction, a question arose:

“Where is the line after which there is no point in repairing it?”

There is no fixed number. But the history of previous renovations matters. The provided material on car locks directly notes that when they are completely worn out and undergo repeated repairs, replacement sometimes becomes more logical than the next restoration.

You need to look not only at the price of today's repairs

Let's say:

• the first repair is inexpensive;
• second - too;
• third - one more.

In total, the owner could already spend the cost of the new mechanism.

What else to consider

• age of the lock;
• availability of parts;
• failure rate;
• safety;
• probability of the next malfunction.

Why should the master offer both options

If repair is possible, it is useful for the client to know: repair costs X and replacement costs Y with an explanation of the pros and cons.

When repairs are still normal

If there were malfunctions:

• different;
• small;
• rarely repeated

This does not mean that after two jobs the lock must be thrown away.
