If you are able to take some photos of this lock as you pull it apart to install the repeater sticker, I would be very grateful.
I am looking for something similar. The ones I have tried have the antenna in a position which makes me moving it (other than exterior to the lock) almost impossible, and the keypad causes issues putting the sticker on the underside.
I am hoping the touchpad on this may allow you to put the sticker on the opposite side of the board to the keypad???
Anyway would appreciate knowing how you go.
