So I went diving towards evening last week and did what I usually do, take my Highlander key and put it on a key ring on a plastic clip hanging on my harness. Had had no problem doing that for quite a few dives. The surge was tough that day and entry/exit was exciting and none-too-graceful rolling over some rocks. It was during entry that my key and clip must have broken from my harness on the rocks, the loss not to be discovered until the end of the dive at which time darkness was coming on pretty quick. Borrowed a cell phone from my buddy and called my wife who came down (about thirty minute drive) to find me sitting in the dark in my wetsuit beside the Highlander swatting mosquitos in total darkness. (I did find the key on a later dive so saved about $150 in replacement costs!) Anyway, now I use a valet key (nothing computerized or electronic about it) that I had cut at the local hardware store. It gets me in the car and even turns on the accessories but does not start the car. I carry it on a key ring on my forefinger under my glove (and now lock the regular key inside the vehicle). Seems to be working good so far. Anybody else had some "key" issues?
