1 Answers
Car smart key batteries typically last two to three years. Here are the detailed specifications of car key batteries: 1. Car key battery models: The battery consists of either three 3-volt button cells or one 9-volt battery. 2. Method for replacing car key button batteries: Remove the hidden mechanical key from the remote, insert it into the marked position, then use a prying motion to lift the key casing. Remove the old battery and install the new one. Replace the key cover and press it firmly into place, ensuring the battery's positive and negative terminals are not reversed. Finally, reinsert the mechanical key.
