Let's call the client Maxim. One day the car stopped opening remotely. The key fob gave a signal, but the driver's door did not respond. At the same time, the door was opened with an ordinary metal key.
Maxim decided:
“The door lock probably needs to be changed.”
But if the mechanical part is working, the problem may be in a completely different place. In the source material, among the faults being repaired, problems with the central locking are specifically mentioned, when the mechanics remain working, but the electrical part requires diagnostics.
Why is it important to separate symptoms
Helpful to understand: Does the physical key work? If so, the cylinder is at least performing its primary mechanical function. Further questions may concern:
- drive;
- electricians;
- central locking;
- keychain;
- food.
Why replacing the cylinder may not change anything
If the fault is in the drive or electronics, a new mechanical cylinder will behave in exactly the same way. Therefore, diagnosis is needed first.
What data is useful to report
For example:
- do other doors work;
- does the car respond to the key fob;
- is the drive audible?
- does the door open with a physical key;
- when the problem appeared.
This information helps separate the mechanical and electrical parts.
