What is the gate made of? At several pools I built, we had a steel gate that we welded a box on. The box was drilled so that an entrance lock could be utilized.
If your gate is steel or aluminum, can you add the box and use something like in the pictures below?
Or maybe a mag lock?
The website I got the pictures from is in the UK, but they have to have them here.
