Is it possible to fit a lock to a 6 foot wooden gate that can be operated
from both sides?

Currently it can only be locked from inside my garden using a simple sliding
bolt. But if I leave my property through the gate I cannot lock the gate
behind me.

Obviously it can't be a sliding bolt on the outside as anyone could lock me
in. Only thing I can think of so far is to cut small holes in the gate and
fence, then loop a chain through that I could padlock on the outside as I
needed to.
