Well I had similar problems to everyone on here tried fuses ect , sometimes it would work for a short while then not, fob will only re sinc if it's not already synced ,the common factor in all of these threads is everyone keeps taking the key constantly in and out the ignition barrel, the car thinks the key is in the barrel, starting the car , so renders the unlock/lock function fob and door , immobile, turn key slowly backwards and if want for a better word jiggle it all way back , wd40 helps not too much, releasing the white pin in barrel so car knows the key is out sorry I'm not very technical but it works, worse case sinario new barrel, good luck all.
