Nissan micra k12 2008 acenta with nissan note n-tec 16" wheels & tyres are 185/55/16. Turned out alright i think. But i have a problem with the central locking (key fob) if i press to unlock the car only the drivers door opens and i have to press twice to allow the boot door to open but all the other doors stay locked shut until i get in the car and press the unlock button by the handbrake. any idea whats going wrong or how to fix this?
