Did your battery go flat (I mean, really dead) any earlier? If so, then I would say: Take the battery to any car workshop and have it tested. Lead acid batteries will not survive if they go completely empty. If the battery is still okay, then it sounds indeed like a weird relays problem. Is the car completely dry? No moisture problems anywhere (not even in the boot/trunk)? Unlikely to be the cause, but just to take it off the list: Same problem with your spare key? Arjen.
