I've a 3-door, 2011 Punto Mylife and not had any issues until now.

When I click my key fob to lock or unlock the car it works intermittently, or will only lock/unlock the passenger door; the boot locks/unlocks without any problems. If I lock the car using just the key, both doors lock and unlock without any problems.

I've changed the battery on the key fob and the issue continues.

Any assistance would be greatly appreciated.
