OK, I bought one of these, but...

I'm going to take it, and the WITZ case on my next dive, with nothing in them.
I was able to get a non-electronic key from the Mazda dealer. The steel key will only open the door, not start the car. In some later Mazdas (and the Infiniti I used to have) they make it very difficult to lock the electronic key in the car. Some local surfers claim they have to wrap the electronic key in tinfoil and put it in the trunk.
Science experiment and results coming soon.
