Okay, first off, make sure the fuse is good and breaker isn't tripped. Look in the Junction Block (passenger's footwell) for Fuse 15 and Circuit Breaker 28.
Otherwise it's time to bust out the multimeter. The door lock circuits are complicated. The master module is in the passenger door but there's a switch that will break everything in the driver door, part of the module you replaced. The door locks are susceptible to broken wires between the door and body, just like the windows and speakers.
Here are some diagrams and pinouts that will help you out:

before he gets too far into troubleshooting he should solder the control boards. If that doesn't work then start troubleshooting. Cold solder joints are very common.

Haven't found the problem yet but I did take my key fab apart and the negative post wasn't making contact with the panel inside the fab so now when I click the unlock button it honk and when I unlock it you can tell it tries but it doesn't actually perform the task
