How to replace the key battery of a Lexus NX 300

Model: Lexus NX MK 1 - Years 2014-2021
Part: Key

We start by pressing and holding the button located on the side of the electric key of our Lexus NX 300, and then extract the internal physical key. After we have done this, with the help of the emergency key to pry, we will have to disengage and remove the back side of the key, to then disengage and remove the motherboard of the key. Once we have removed the key motherboard, we will have reached the low battery, which we will have to extract. When we have removed the battery, the disassembly will be complete. To mount the new battery on the key of our Lexus NX 300, we will have to repeat this procedure in reverse, and the replacement will be completed.
