I’ve searched for this particular issue all over with no luck. It may be a symptom of a common problem, though. I have a 2003 s60 with 55k miles. Just recently, when I get out to lock my door with the key fob nothing happens. No lock, unlock, trunk etc. after waiting about 30 seconds, suddenly it works. Seems it works when the dome light dims but not before. Everything else works fine as usual. Any ideas?
