How to Replace the Key Battery of the Mitsubishi ASX

Model: Mitsubishi Asx MK 1 - Years 2010-2023
Part: Key

Today, you will learn how to replace the battery in a Mitsubishi ASX key. You will need to purchase a 3 Volt CR2032 battery for the replacement. Start by inserting a small flat-head screwdriver into the end of the remote to lever it open. Once the remote is open, remove the old battery and insert the new one. Finish by closing the remote and testing its functionality near the vehicle. If the key still does not work, reprogramming may be necessary, which must be done inside the vehicle by opening and closing the car multiple times.
