What to do in case of central locking malfunction in the Mercedes B-Class?
Years 2019-2026

Answer

The central locking system of the Mercedes B-Class requires communication between the remote control and the control unit to work. If this communication does not happen then problems arise. But how to solve them? Starting with the key, which is the easiest element to control. We check that the battery is charged and that the transponder is not damaged. If we have it, let's try to use a spare key and if the central locking works with it then we have to replace the first key (or more simply just the battery). If not, we need to have the ECU checked and fixed.
