    Heres a suggestion: To make the next version of the Keyfobs water proof, or offer a waterproof version as an option.

    This is something that I have always been bothered with. The key fob for my Prius has gone through the laundry several times.

    Way beyond waterproof, the idea of the Tesla Key is just at the beginning of a long evolution. The current system is very expensive. Have you checked into the cost of a replacement or spare key?

    A Tesla Key is a a wearable or carryable bit of technology that can be integrated with other functions and assume other forms. It could be a universal key to give access to anything that's designed to be compatible. It could be integrated with a portable memory device that also holds all of your passwords and access codes. It could also like other current products have biometric and/or voice ID to protect these assets. It could of course be completely programmable to function however the owner prefers. Want your key to ask for your voice confirmation or thumbprint under certain circumstances? Want it to erase everthing and go inert under others?

    Was going to post a link to the forums where I saw this, but since they are down, here is a solution they had on there:

    1) The first quick solution was a "zip lock" bag of sorts called "LokSak". It's basically a heavier duty zip lock bag, which I purchased on Amazon. (I purchased the 5" x 4" which was the smallest I could fine). It works well. I zip it shut and drop it in my wetsuit (at the small of my back) and go. The nice part about this is you can easily test the bag and confirm it's water tight.
    2) Next came the idea of using Silicone Tape, which I hadn't ever heard of until I saw it at a boat show and when I saw it the light bulb went off. Great product. The brand I have used is called "Rescue Tape". It comes in 1" and 2" rolls. I've used the 1" as it was readily available at the marine supply store. I first wrapped the key fob with one layer and minimal overlap and tested it in the sink. Everything seemed fine, but I thought I'll cut the tape off and check inside....and found some moisture. The key was fine, but needless to say this made me nervous. I tried again and this time pulled the silicone tape really tight (which is key) and went around the key twice to make sure the silicone tape (which adheres to itself) had plenty of chance to do so. I tested again, and cut the tape off (note the tape does NOT stick to the key fob which is nice) and it was bone dry. So, I've used this for awhile, but it made the key a bit bulky and much less attractive. So, idea #3 was born....and the best one yet....
    3) Plasti Dip - A liquid rubber product you can buy in a 14 oz. can for about $12. First I tested it by dipping the key in half way and let it dry. (I wanted to see if the Plasti Dip would stick to the key and make it difficult/impossible to get off when it was time to change the battery, which it didn't surprisingly.) So, then I fully dipped the key, from a paperclip, let it dry (directions say 4 hours minimum before use), put it in a sink full of water, pulled it out, dried it off and proceed to peel off the Plasti Dip coating (which was easy). Again, the key was bone dry and I finally found the perfect solution for me.
    My final configuration is a thin nylon string (like what you find at the end of a digital camera strap) and then two coats of the Plasti Dip, which fully coat the key fob and a small portion of the nylon string. I've only been using it for about a month now, but the Plasti Dip is surprisingly strong....and now I've got a key ring loop if I want to add it to my key chain, which I've gotten used to not having. I suppose it will save my key when it goes into the washing machine by mistake. I figure it's only a matter of time now that I don't keep it on a key chain!
    Sorry, I couldn't figure out how to post pictures! I'm laying home with flu and I've lost my patients so the text is all I've got for you for now.

    I'm going to spray mine with NeverWet. Amazing stuff.

    Neverwet has some huge probems. It messes up the finish, it only worst for a short period of time, ... But worst of all, even the manufacturer suggests to NOT use it on electronic devices. I would go with plastidip. It has been WELL TESTED over many years, and will peel off easily if you want to take it off or need to change the battery.

    Holy Necro! Also, the new keycard thing is obviously waterproof (and for that matter so is my phone). Also why is this in "future vehicles"?
