Which is what eventually happened. I was a little surprised that they require the password for all cases, and that they had no way of dealing with a customer who didn't wish to share his password. And also that, according to them, so few people have a problem with this.
Need to reverse that logic - they "require it" of everyone, since so few people care. If everyone acted as you did, the "requirement" would become less so.
They can test the machine easily enough with a boot disk. Then, they can call you in, let you enter the password, and do the driver updates quickly.
Just the same as the geyser repairman will need to spend an hour or two in your presence, so they should. It is a simple problem of too many people having no interest in their own security.
