Don't understand this computer -- This is the second time I filled this in. I have since ordered a replacement collar Ms 4 (I think) I was surprised there was no battery in it. It seemed that it was taken apart and the battery removed. I haven't put it on as I managed to use the broken one.

It worked! My door opens and shuts again. Easy install and I love that you can buy parts!

Motor was easy to replace and works great

Worked like a charm! With 4 dogs, I really appreciated the quick service.

Amazing service! Received the part in 3 days and door back up and running the same day.
Thank you!!
