Door salesman here. If that is a wooden door, I would highly suggest not doing that. You severely compromise the integrity of the door drilling a hole in it outside of the lock lock area.

Steel or fiberglass door is not a problem. Make sure there is a sleeve to protect the wire from rubbing on the skin of the door causing a short. Especially if it is steel.

All that being said, I still wouldn’t do it. Replacing that door will cost thousands. Fixing it would be a lot of paint and Bondo.

I THOUGHT that is what the article said, but that seems like it was translated 2-3 times before it made it to English.
