In case anyone ever needed to know, the Gen 3 key fob can withstand at least one cycle in the washing machine. LoL I think it actually improved the range of it a little bit.
No, I didn’t. There was no need to. There was not enough water in it to even make a fuss about, which I found surprising.
Solid state so not completely surprised. You can wash (some) motherboards in a dishwasher. Did you open it up? The battery and contacts should be checked. Think I'd replace the battery.
It happened to me about 5 years ago. Opened it up, took it apart, ran alcohol over it, let it dry. After putting back together, it was fine.
I've washed my Town & Country's remote twice. It does have a rubber seal. No problems and didn't need to replace the battery. I never washed the one for the Prius. It would cost too much for a new one so I guess I pay more attention!
This happened to me and my fob was done so i ordered a new one online from https://www.toyotapartsprime.com/ .
