极星（沃尔沃）防水小钥匙可替换外壳,Polestar (Volvo) Waterproof Small Key Replaceable Shell

Polestar (Volvo) Waterproof Small Key Replaceable Shell, 3D Printed. When the battery of the small key fails, you can open the shell and replace the battery yourself. The original battery can be directly installed in the replacement shell, allowing normal use but it will no longer be waterproof. The shell is divided into two parts: an inner case and a hard shell. The hard shell and the inner case are secured with hidden clips, so there is no need to worry about loosening during normal use.
