I carry a long crowbar around with me.
It's true as well  .
I get the stepladder out, lean over, and hook the crowbar around the bolt and undo it.  Doesn't work if the bolt is too far down or if they use a padlock.
I do have a collection of gate keys too.
I would say that if erithwc isn't prepared to carry keys and if the customer is not prepared to leave it unlocked for the day, then the position is stalemate and to go elsewhere to earn your money.

I split my ladders and get over locked gates that way. Some may say that this is unprofessional, but it gets the job done as both customers and I are happy.

some i text and others i either climb over using 8ft single pointer or lean over and whack the bolt(if its half way down the gate with my T MOP!!).

on the odd rare occasion i split my 2 section ladders and slide one over the gate.luckily for me i dont have a lot of locked gates on my round at all really!!!if im unlucky 3 or 4 on one working day!!!
