Are you properly pointing to the IR receiver on the door with your key? This feature does not work over the radio.

If you are doing that, the IR receiver at the door is probably failing (if you don't have issues starting the car, the IR part of the smart key is working).

Of course it could also be a dead (almost) battery in the key (you know the battery is not needed to start the car). You can test the key battery, see instructions from your user guide.

Do you have an IR window on both front doors? Could try on the other side.

Windows out of sync ?
Try re-synchronizing your windows, ( check your manual for detailed instructions )

That is a good point generally on the window issue but the OP stated "it sometimes works and sometimes does not". I concluded that it would not be a sync issue but perhaps it was working sometimes when the windows had been synchronised and sometimes when battery had been taken off, it did not.

It would be essential to post everything that might be related when asking a question.

sorry i didnt explain it clear enuff

when i said it worked b4 i meant that it worked out the blue once but never worked again.

I tried to re sync the windows and also check to make sure remote battery was good.

try the other side of the car. my keyless go works fine but i cant unlock or lock the drivers side door but it works perfect on all the other doors so from what i read on here my door handle is bad. but the windows work when i point it at the passenger door you just have to be really close.i had a 00 jaguar s type v8 with the same feature and it worked from far away so i dont know why mercedes made it to where i have to be real close. so most likely its your door handle if all your batterys are good.
