What exactly did you program and how? I would probably consider undoing that and start over. Was a battery maintainer used? If you flashed a module on a lower voltage you might get some interesting results

.There's a child lock switch on the inside but I think that just prevents the inner door handle from working, not sure if it messes with the lock mechanism at all.

I've encountered some strange behavior with the lock mechanism on mine a couple times but haven't picked that battle yet. Just keeping it unlocked for now. I have to code out the beeping first, if anyone knows how to do that. I also have a parasitic draw .. and the left rear exterior door handle failed yesterday but I smacked it back into place enough for now. These are easy fixes right.
