Tesla sedan afraid of water?

Tesla sedan afraid of water?
Please let us know if your Tesla sedan is fine when it stays long time with water.

Tesla key is dead with water:
My friend did a test before, he put the key into the washing machine to wash out more than 20 minutes, after finished, quickly removed the battery and then gently knocked out the remaining water, and a night with a fan blowing to see it is fine or not.
Next day, he found this key is DEAD, could not use any more.
He suggest us that we no need to pay a $220 to take a risk. All Tesla key should with a silicone keychain.
Tesla keychain is topfit.
