When a fault occurs in the remote, it becomes impossible to open and close the doors remotely. Fortunately, using the mechanical key allows access to the vehicle.

Daily use of the remote can lead to wear of the internal components, especially at the solder joints between the battery contacts and the printed circuit board. To resolve this issue, simply disassemble the remote and extract the printed circuit board.

Using a small electronic soldering iron and suitable solder wire, completely redo the solder joints. If the plastic casing is damaged, it can also be replaced.
