What to do with car keys?

[CUunderH2O]

Well, it turns out that there were no worries. The area we did our dives in was a local beach with a fair amount of people (both divers & non-divers), with a few shore support people, so everything turned out fine in the end. I will be buying a little dry box for the future, however, in case there is no shore support on other dives.

Thanks for all your answers/suggestions!

My Ford F150 has a keypad on it that allows you to lock the truck and open it with a combination. I think you can by it after market too.

I pull my xterra's key of the ring and zip tie it to a D-ring on my BC while beach diving. It works greats. To take it off, I use my knife or even simpler (and safer for the BC) is just twist it around about twenty times until the zip tie breaks off.

And what do you do when the zip-tie breaks mid-dive, aabond? Uh oh...

I'd put it in a pocket, or something a little more secure than a zip-tie, dude.
