[FernandoRose]

Lexus car key battery replacement method: 1. Remove the battery: Take off the mechanical part of the key, insert a flat-head screwdriver (or the flat-head part of the mechanical key) into the groove, rotate it left and right to separate the electronic key shell into two halves, then lift the chip part to see the round button battery. Remove the battery and install a new button lithium battery after confirming the positive and negative sides. 2. Reassembly: After installing the new button lithium battery, cover the chip again, reassemble the key, and press any button on the key. If the light turns on, it means the electronic key is working properly.
