Key-fob Problem

HI, have 2001 ML55AMG didnt use it for about 2 months wile fixing few things. When i was all done my key-fob stopped locking and unlocking doors. Got new batteries and tried to resynchronize the fob. Turn the key to position 2 then to 0 then wile holding lock button press unlock 5 times.
When i did it before on my ML cars when i press unlock button 5th time doors lock and then i press any button to confirm its working, it unlocked the car and it was done and working. Well this time after 5th time nothing happens. Only after 5 times when i let it go and press lock button it will lock the car and light will blink 2 or 3 times but after that nothing works anyway. tried to do it few times, get the same result every time. Is it my fob or my car? what should i do? thanks
