The battery of the Smart remote can be replaced by using an object to pry open the groove that divides the two halves of the shell: once the key is opened, it will be possible to locate the battery inside the device. This can be removed from its housing at the center of the coding chip, and a new one can then be inserted in its place: it will be necessary to secure it and reposition the chip in the remote.

By doing this, the device can be closed, ensuring that everything functions correctly.
