How to Replace a Lost Car Electric Key?

[IvanLynn]

Look at the position of the lock teeth. There is a strip-shaped seal behind the lock teeth, mostly sealed with a copper strip, while older models use an aluminum strip. Use a sharp object to slowly pry it open, revealing springs inside. Behind each spring, there are two teeth: one fixed tooth and one movable tooth. After removing them, insert the key you want to duplicate. Take out the lock cylinder and reinsert the movable teeth. File down any teeth that exceed the height of the lock cylinder's surface. Then reassemble and test for smooth operation. Once tested successfully, reinstall the lock cylinder, secure the fixed teeth, place the springs back, and seal the strip with a heavy object. Finally, reinstall the lock to complete the process.
