I have an honda civic 1.5 Vtec-e from 1998. It has central locking, but I wanted to install a keyless entry system. So I looked up the correct wires I needed. The white for the constant power, the black for the ground and the green/orange and green/white for locking and unlocking the doors. However after installing my central lock does not work on the driver side anymore. I can instert the key and turn only one side because the other seems to be blocked and nothing happens at all. The passenger side is fine. What could be the problem? All fuses are alright and everything else still works.
