3 button smart remote doesn't unlock doors?
 

I'm new to this site and am finding it very difficult to navigate around. I can't seem to get a specific answer on a search and don't know how to make a specific post....

I want to know if anyone else has had a problem with the remote not unlocking the doors on a W209 CLK 270? If so how is it fixed.

Note I have changed the batteries in the remote.

Thanks
Dan
