When you replaced the lock did you have the liftgate calibrated for open/close position?

I did not. It worked right away when I replaced the lock. Here is the rundown explained a bit better. Maybe after reading it you can tell me if it's a calibration issue. Remember that it's only a 2013 crew.
1. Hatch stopped latching closed, wife and kids kept slamming it thinking that would help (it didn't) so the powered lift arm and the powered latch were toast.
2. I replaced the powered latch with a new one and it latches every time now. The new problem is that it will no longer unlock itself. I can hear it cycling and if you watch it from inside it flexes but won't release.
3. My plan is to buy the bracket I need to replaced the powered arm with the standard strut I already have for it.
4. The second part is to replace the powered latch with a mechanical one so that when I pull up on the handle it releases the latch. I know there is still an electrical unlock component but it looks like I already have what's necessary wiring wise to make that work even if I have to cannibalize wiring from the existing one.
We had a 2011 with the non powered lift opener and that's what I'm aiming for
