The front passenger door lock of my 2003 Pilot EX-L stopped responding to the keyless remote or the interior power open/close buttons on the driver and front seat passenger doors several years ago. The only way to lock/unlock front passenger door is to manually use the latch inside or manually insert key in the front passenger side door. When using the actual key to lock/unlock the front passenger door, all rear vehicle locks work as expected. Now the similar issue has emerged with the front driver side door. However driver key lock only has ability to lock all doors, unlocking all doors from drivers door lock is not possible with key. Incidentally, rear doors & hatch still operate properly from keyless entry remote. With these problems it's not possible to activate alarm with remote entry device until both front doors are manually locked. Is there a simple fix? Can repairs be performed DIY or at a non-dealer automotive service center (or possibly auto-glass repair shop)? Do the door lock actuators need to be replaced/adjusted or is there a possible wiring issue? Any feedback would be appreciated. TIA, RK
