How to Replace the Battery in a Langdong Car Key?

[SanRuth]

Langdong car key battery replacement method is as follows: First, hold both ends of the car key with both hands and push and pull in opposite directions to open the back cover of the key; then remove the old battery and replace it with a new one of the same model; finally, push the back cover back along one side to complete the battery replacement. Extension: Smart car keys must not get wet. If they do, the internal circuits may burn out, causing the remote control to malfunction. If your smart car key gets wet, do not shake it vigorously, as this can cause water to spread to other important circuits, and do not immediately attempt to unlock the car with the remote. The correct approach is to open the key casing, lay it flat, and use a hair dryer to dry it before taking it to a repair shop for inspection.
