Where/how do I find the video clip?My 2011 sprinter both sets intermittent fail then stoped. When the led did blink it would lock. I ordered a new key £140 from merc. I split my old key with a hot stanly knife.
Then opened each micro switch and cleaned and put back together. They are just clipped in place but are very small so need good eyes. Instantly all the buttons work so glued the fob back together. I have put a clip on YouTube to help others.
