Interestingly both my Hollis and Oceanic came with the identical type of key. Battery replacement is dead easy and the O-ring is standard size. Always carry couple of battery and O-ring on any diving trip.

Both computers were made by Pelagic Pressure Systems, formerly a division of Oceanic (as is Hollis). PPS was sold to Aqualung. Suunto is a separate company.

I've changed batteries on Suunto computers many times and never had a problem. I did my HelO2 the day before yesterday and dived with it yesterday. It didn't implode! I've never changed an O ring during battery replacement. I try not to dislodge the O ring and leave it in place. I normally use two micro screwdrivers to open the securing ring or as of two days ago, two small nails as I'm on holiday and that's all I could find in the apartment.

The only point of interest was that I bought a CR2450N battery. Previously, I've always used a CR2450. Apparently, the CR2450N has a lip and is the correct choice for Suunto according to Google.
