i fixed it;
luckily i found genuine remote control in Ebay it cost me 30 USD. then i took the fob and buttons only and replace my old ones ....and it works
i needed to give to the new remote and my old one to electronic technician in Karamah and he took 100 Dirhems to replace my old buttons and the fob.
note i didn't touch the CPU of my remote just the buttons
