How to change the battery of the key for the Peugeot 508

Model: Peugeot 508 MK 1 - Years 2010-2018
Part: Key

Replacing the battery of the remote key for this model from Peugeot (the procedure is the same for many other models from the French manufacturer) is extremely simple as you only need to remove the rear shell of the key, which bears the manufacturer's logo: use a small flat screwdriver to lever at the front of the key to remove the shell; at this point, the battery compartment (model CR 2032, 3 Volt) is immediately accessible and can be replaced with a new one, ensuring the correct polarity.
