In this case, the contacts should be carefully wiped with alcohol.

⚠️ Attention! Do not attempt to open the key fob using brute force or a hammer. Plastic of the case Skoda It is fragile enough at low temperatures and can crack, which will lead to a leakage violation.

What to do if the case does not open?

If the latches do not respond, check if the mechanical key is fully extended. Sometimes the key lock lock locks the mechanism of the housing connector. Try to sway the halves slightly without making a significant effort, or heat the fob with a hairdryer at a minimum temperature so that the plastic becomes slightly more elastic.

Replacing the battery and assembling the device

Once the body is open, you will see the power element held by a metal bracket or simply lying in the recess. Battery extraction It is made by lightly tweaking it from the edge with a plastic spatula or finger. Make sure you don’t scratch the contacts on the board.
