2006 landcruiser question

Hi all. I have a 2006 landcruiser  , UK model. I think it's known as Prado in other countries.  It has a 3 litre diesel engine. I have a few questions,  if people could advise that would be nice.  Is it true that in icy cold weather if you use the power heat button (makes the car idle at higher than normal revs) that's its bad for the injectors? I'm sure i read it somewhere.  Anyway yeah my car sounds horrible until up to temp. Like a crank rattle! Any advice plz? Also it keeps auto locking the doors when engine is off . I had to smash a window last year when I left the keys inside, closed the boot door, it had auto locked before door was closed lol ! Cheers guys I look forward to any posts.

Injectors, get them looked at ASAP
