My 2003-Pilot now is approaching 60k Miles. The front passenger door lock no longer responds to the keyless remote or the interior power open/close buttons on the driver and front seat passenger doors. The only way to lock/unlock this door is to manually use the latch inside or the key on the front passenger door. This is real inconvience upon leaving the vehicle when trying to activate alarm system. Note: When using the actual key to lock/unlock the front passenger door, all vehicle locks work as expected. Any thoughts on what is broken. Is this a simple repair? TIA, RK
