Thanks @lquidfire.
Those procedures didn't work for me initially; but based on the error messages I found this info regarding firewalls. I'm on a mobile connection abroad and had no idea, but there may indeed be some firewall, because gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys D95426E309C0492990D8E8E2824A5E0010A04D46
(note the :80) did the trick to import the key.
By now, eid-mw is up and running :-) Many thanks for AURing it!

@cherkaba: See the link in the PKGBUILD.
The 'release' packages are signed by the key you mention (and found here: https://eid.belgium.be/en/linux-eid-software-installation).
However, sources are not signed with that key, but with the one mentioned here: https://files.eid.belgium.be/info.html (as explained in the PKGBUILD).
I hope this helps!
