How to Replace a Car Key?

[StValentina]

First, remove the mechanical key, then you can see the gap on the plastic shell. Use a tool to gently pry along the gap, being careful not to touch the internal circuit during the prying process to prevent damage to the electrical components. Pay attention to the positive and negative directions of the key battery and remember them, then remove the battery for replacement. Ensure the position is correctly aligned to prevent damage to the internal circuit during the pressing process. After installation, test the key's functions to ensure they are working properly.
