How to Replace the Battery in a 10th Generation Civic Car Key?

[Lori]

Hold the metal tip of the key with your fingers and pull out the mechanical key from it. Insert the mechanical key into the plastic slot in the key placement area to pry open the back cover of the remote key. Remove the old battery from inside the key, making sure to dispose of the used battery properly. Insert a new battery of the same model into the key, then reassemble the key by reversing the disassembly steps. Do not leave the key exposed in extremely cold environments below 0°C or extremely hot environments above 50°C, as this will significantly reduce the battery's lifespan.
