Back to the original question:
I have the best luck with a key pouch. Since they are flexible, there is essentially no pressure difference from outside the pouch and I have had zero leaks. Mine has a lanyard, so I can wear it under my wetsuit and not worry about the key.
I have also used a hard case and learned to despise them. Since they deal with the same pressure a camera case does, they are prone to leakage especially since you are not likely to take as much care with keeping the o-ring lubed and clean. I had 2 leaks, both small but worried me and a avoid using it now.
Lastly, with many chipped keys, you can get a duplicate made for a lot less if you have 2 working keys. Seems silly, but with 2 working keys on some cars you can add a 3rd key yourself. With only 1 working key for security reasons, you have to have the dealer reprogram the computer in the car and the cost can double/triple.
