Diagnostics
The system inspection process depends on the symptoms of failure. At the absence of one or more locking elements response corresponding activators and electrical elements are checked. If the whole system is not working, then the problem may be in the main board. You should also check the wiring for a short circuit or a blown fuse.
If there is no remote control signal it is necessary to check the batteries power as well as the signal itself. This can be done only in a specialized service center.
Central locking has no definite lifespan. With careful use and no mechanical damage it can serve during the entire life of the car. However, it is recommended to thoroughly check the wiring, drives and the main board and to clean the elements every few years.
Repair and replacement of the central lock components
The repair order depends on the fault nature. At one drive failure the corresponding door lining is removed. It is worth noting that solenoid drives fail more often than motor drives.
The activator if fails is completely replaced. You can restore and isolate damaged wiring, but it is recommended to replace it immediately.
Restoring a damaged remote control key is only possible in a garage with special equipment.
In case of the main board damage or closure it only needs to be replaced. Unfortunately, its price will not delight you.
