configuring Yale Keyless Lock (Fiveways BN1)

I have fitted locks for 40 years, have an MSc in IT Human interfaces... I am autistic and am left insensible by the illogical setup of these things... oh and the incomplete instructions which expect you to ring their 'help' line because they couldnt be bothered to provide logical instructions in the first place. Of course the location of the door in question has no reception for mobiles...and they expect you to hold a fone whilst also manipulating the lock. The last thing any of us need is more batteries in our lives... the customer 'service' from Yale is a special kind of nightmare. Any tips any help perhaps we can interact online...
