First, please do not turn on the power or operate any buttons, and dry it thoroughly. If moisture remains inside, it may cause malfunction. After drying completely, replace the batteries with new ones (always check the +/− orientation) and try the authentication again. If you still cannot authenticate, it may be necessary to check, reconfigure, or inspect the main unit. For your safety, we provide detailed instructions individually—please contact us with the product name and symptoms (the wet conditions and the current behavior). Even if it works again after drying, we do not recommend continuing to use a key fob that has been wet. Depending on the situation, we may also be able to discuss a replacement.
