Remote key entry
 

Hi all I have a 2012 GL 450 the remote front driver side entry door handle does not work anymore what is an easy fix or do I need to replace the whole handle please advise

The common cause is the black rubber button has cracked and let water into the electronics. Cheapest/easiest solution is to swap it with the driver's side rear. It's maybe a 30 minute job. Just google for the process - there's plenty of info out there. The driver's rear won't operate... but it hasn't bothered me for about a year, now!

Ok thanks that’s a great idea
