Rattle comes from under hood for about 15=20 seconds after I enter car even if i dont start it or also when i unlock door remotely with keyfob.Since it doesnt matter if engine is on I was thinking maybe an alternator problem but don't know

try getting in the car but not shutting the door and see if the noise is still there this is .not an alternator issue for sure,sounds like something loose in the door or maybe a heat shield on the exhaust.if you stiil hear it without shutting the door try tapping lightly on the tailpipe and see if you hear it.
