Unscrewed door latch and replaced it with the new door latch (1-2 min). Unscrewed outer plate from door lock assembly. Removed door lock assembly from its outer plate and unplugged wiring. Replaced with new door lock assembly, plugged back in, tightened some screws, double-checked alignment between latch & lock assembly was good and the project was done. Incredibly easy and saved about $150 not having a repair tech come out to fix it.
