I have a 2007 Honda Accord 2.4 SE. When I push the lock/unlock button on key fob it will not unlock/lock the doors. Only time it does, is if the driver door is unlocked. At that point, it does all doors but the driver door. All other ways of locking/unlocking such as the buttons on master switch on inside door panel operate all locks minus the driver door. The only way I can actually lock/unlock all doors is by placing key into driver door key hole and turning key manually. Any input on what causes this? Any info at all on what I need to replace? Please help. Thanks in advance.
