they told me its look like not key transponder fault but something with a car and anti theft system. Probably have to visit dealer but first I'll have a look for other ways. Just wonder is that may be because I don't lock my car (my remote not working even with new battery), I've try reprogram with people advices from internet but doesn't work for me. When that's happening Iv'e got code's reading P1260 and B1601.
