A few weeks ago I was rear-ended in a snowstorm and had to have my trunk replaced. The body shop ordered a new trunk lock assembly with IR receiver and had it keyed and coded by MB. At present, the key turns in the lock correctly, and when you push the button on the remote the lights flash red and green as they should, however when I do this the doors do not lock or unlock like they used to.
If you're sitting inside the car and push the door lock button, all the locks drop correctly, including the trunk and fuel door locks, so it appears that there is not a vacuum connection issue. Is there some sort of other synchronizing that needs to be done now with the new lock, and if so, does anyone have any advice for me?
Many thanks,
J
