Okay. So if I understand this, when you press the lock button on either front door, they will both lock. However, when you press the unlock button on either side, neither will unlock?
If this is the case, it still sounds like the master switch. The way it works is anything the either switch does runs through the master switch. So if the master switch is failed then it will have the same issue on both sides.
