Hi, I currently I am using a combi door using keys. I would like to change into a digital lock. Anyone know if I Into a digital lock to my combi door? Anyone know which shop that can fix digital lock to a combi door? Please assist. My combi door is still in a great shape. I do not want to change the door just to use a digital lock. I have attached 2 photos of my lock on the combi door. Thanks in advance.
