FOB pouches...
Attempting above method tomorrow on myself in car first
From old Subaru the process was having an extra FOB and locking one in the car and carrying one
These work:

I highly recommend AGAINST leaving a key-fob in a car. In the event someone breaks in and digs through things and finds it, it's more than the contents of the car they'd get away with.
But, if one wanted to make the bad decision of locking a key fob in the car, that pouch prevents the vehicle from detecting it (in my limited test), allowing one to run off with just their phone or some alternative method of unlocking the car (like the hidden physical key, which can get wet unlike the FOB).
My phone is waterproof, my FOB is not, so, it gives me more options when hiking through streams, waterfalls, etc, or when on the beach. Not that I'd make such a bad decision, but, if I did, those are the options I thought of. Lock the FOB inside the car in the pouch, and use the key portion to open the car, or use my phone to open it.
Is this a "Do what I say, not what I do"? scenario? :smile_big: :tango_face_wink:
On a serious note though, I don't plan on doing this. I thought of a better idea, and am just looking for the right thing. I will instead get a form fitting (or close to it) waterproof pouch that can connect to a belt loop or similar. Surfers and body boarders use little waterproof cases all the time for such things... so, I intend on finding one of the appropriate size for the FOB and use that instead.
