Problem changing battery on Suunto D3

Wondering if anyone could help me, I've got a D3 which I haven't used for a while. Problem is I need to change the battery, but can't seem to get the rear cover off as it has pretty much disintegrated at the point that you use to unlock the cover. Anyone had this problem and found a solution, know I can easily get a replacement if I can get the rear cover off, just not sure how to achieve that. . .

I had the same problem. I messed up the coin slot and couldn't twist the cover off. My solution was to heat the tip of a large screwdriver on the gas stove, then stick it into the plastic at 90 degrees to the original slot. It made its own slot, and I was able to remove the cover.

I had the same problem so I bring it to the shop when I need to change the battery. I won't fart around with it. Besides they can check the seals under pressure.

Nice one, Bill I was having the same problem.

Your heated screwdriver was just the trick.

Cheers

This Screwdriver idea is GENIUS! Would just add the probably obvious - once the new slot is formed by the hot screwdriver, cool the screwdriver and the plastic (to let it harden again) before you try to turn the cover.
