@cocosmom : I don't think I would. Ours is self close, and before we just had a sturdy bolt lock to keep the kid next door from letting Chloe out. New gate, need a new lock. We have automatic lights and verbal notification if anyone goes near the drive, gate, or front door, but DH turned it off for some reason.
I guess it would depend on how well you know your handyman. What is to keep him from forgetting the combo or writing it on the fence so he won't forget it?
