hi My 220 lexus (2006) is making noise ))) the doors should open automatically when you stand beside the car with the key fob , but now the doors do not open automatically and starts beeping alarm when I stand near car(driver door). Key fob is working OK,car runs ok. just now I have to open car by key fob (pressing button ''open'') but this problem not allways -sometimes its work like a normal. what could be the problem? it started after locksmith opened the car without a key (then a key-found)
