Disassembly of Remote Key for Battery Replacement

Model: Citroen C4 Picasso MK 1 - Years 2006-2013
Part: Key

Each remote contains a small battery that powers the electronic circuit of the transmitter. When this battery runs out, it becomes impossible to open and close the doors remotely. Fortunately, you can access the vehicle using the mechanical key. Replacing the battery is straightforward; use a small tool to pry open the back of the remote to separate the two plastic halves, remove the battery, and replace it with a new one of the same specifications. These batteries are available at any supermarket. If the plastic casing is damaged, it can also be replaced.
