Have you tried to reteach them yourself ? It might be a short time fix but you would not have to manually unlock all the time? Autogunner.

i bring it back under warranty,, but i am afraid of what they will charge when my warranty runs out..it seems like it happens alot because at my mass dealership it has a sign saying that , mercedez will need all the keys for the car, if you are there for a remote problem.

I misread your post I think. Is you liftgate the only thing that will not unlock? Also if you take it to the dealer and they have to replace the AAM or EAM then they will need both keys to reteach them, and if they install a new FBM then you will get new keys and a door lock. If only your liftgate wont open then it is probably a switch or servo in the Liftgate itself. Autogunner.

Does the key start the truck. If it does.... I would follow the manuals instructions on installing new batteries, and resyncronizing the key. If all else fail then take it to the dealer. Remember you only have a set amount of keys that can be issued to that truck.
