What to lubricate multi-point locking mechanism with?

What should I use please to lubricate the 3-point locking mechanism on my aluminium external front door? I assume that it is the same as a upvc door mechanism.
I would have used grease but then thought WD-40 and then maybe, graphite powder.
Thanks

In hindsight,I probably didn't need to remove it from the door (maybe) :-/

Light oil like 3 in 1 or silicone based oils for main gearbox, for the key barrel use graphite powder
