Cant unlock door
 

craziest thing. I have a 2007 CRV and the electronic key will lock the door and the horn will honk but when i hit the unlock button there is a faint unlock sound but all the doors are still locked. I also tried to manually insert the key into the driver side door to unlock the door and that will not work either. Bad Fuse??? I'm completely at a loss. No accidents nor have i recently changed the battery but the battery works. Any answers will help cause i'm about to call a locksmith
