rvf Posted January 23, 2012 Share Posted January 23, 2012 2003 RX300, 120,000 miles. Remote door lock/unlock buttons now operate only the rear passenger and rear hatch doors. Front doors must be opened manually with key (happened to passenger door, then driver door, about 2 months apart). Remote device batteries replaced. Fuses okay. Ideas on what the problem is / resolution ? Quote Link to comment Share on other sites More sharing options...

jazzcat Posted January 24, 2012 Share Posted January 24, 2012 You may be parking in an area where the frequency is being disrupted. Does this happen every where? Quote Link to comment Share on other sites More sharing options...
