Anyone know if the little plastic bit that surrounds the door lock button is a) available as a spare part and easy to fit? Its the one with the LED in to indicate deadlocks activated, etc

I have a cracked one on the drivers door and its been annoying me for the last two years so I thought I'd replace it!! Though, thinking about it, going chrome might be nice if its available.... though that means replacing them all! Anyone done this? Is it an easy job that doesn't involve taking the door to pieces?!

Thanks
