This appears to be buck passing between HH and the fire service.
We can only judge and allocate blame based on our experiences of contact with both of you.
When we approached the fire service directly we were visited by two senior officers and the locking facility was restored with surprising speed.
I appreciate that there was some risk with the locks we had, and deduce that you were ready to expose us to an alternative (we consider a greater) risk from intruders if it did not involve expense.

I would like to know how soon all of us will have locks.
