IR Schlüssel geht nach Wassereinwirkung nicht mehr

[ronenfe]

Hi, I have a Twingo 95, no immobilizer, only central locking with ir, it's the round key with round button in the center. I accidentally entered a swimming pool with the key in the pocket and not it doesn't work and I couldn't fix it and find where the problem is. Any suggestion how I can fix it, or find another key? I will have to replace the circuit in the ceiling?



Thanks.
