What should be included in a normal check after installing a new lock

The client's name has been changed.

Let's call the client Mikhail. After installing the new lock, the master turned the key once and said:

“It works.”

Mikhail thought:

“Is this enough?”

For a normal test, more than one movement of the key is desirable. In the original material about the replacement, the last step explicitly states checking and adjusting the new mechanism after installation.

1. Check with the door open

The lock must freely go through the entire operating cycle without load from the door frame. This helps to understand the condition of the mechanism itself.

2. Check with the door closed

Then you need to make sure that:

• crossbars fit normally into the mating part;
• the key does not require much more effort;
• the door does not have to be pressed or lifted.

3. Checking all keys

If there are several keys in the set, it is advisable to make sure that they work the same.

4. Check on both sides

If the design involves working on both sides, you need to make sure that each mode is functioning correctly.

5. Multiple loops

One successful turn does not show stability. Useful several times: open → close → open again.

6. Checking the fittings

After installation there should be nothing:

• hang out noticeably;
• cling;
• move;
• create abnormal resistance.

7. Explanation to the client

The owner must understand:

• how to use the system;
• how many keys I received;
• are there any special features of the work;
• whether any maintenance is required.

Why is it better to do such a check right away?

If the problem is discovered by a technician, it can be fixed before the door is locked again.
