Subary(2010 Outback) ignition key remote door lock function

My 2010 Subaru Outback (Euro spec) has for a long time been bugged with intermittent functioning of the kemote unloc/lock of the ignition key. I changed the battery several times, mistakenly thinking this was the cause. However, when I disassembled the remote unit of the ignition key, I found that the battery contact for the positive pole had come loose from the printed curcuit Board, given intermittent power to the module.
I turned out that the printed curcuit Board can be extracted by gently prying open the Remote unit holding the battery and the Electronics inside. The battery pole contact can then be soldered back in place as a remedy of the problem. As this had happened to both keys fairly parallely I suspect a production or design flaw. Anyway, soldering it back up saved me a lot of money for potentially replacing both keys/Remotes.
The attached pictures are marked up with repair advise for anyone who wants to give it ago with the soldering iron.
