I have experience with losing a 2011 key and fob. The fob looks like 1992, but, the key has the plus sign as well which means chipped.
My son put the keys into a Mr. Potato Head, but I thought we lost it. So rather than pay the dealer, we paid Batteries+ $180.

Well, we found the lost key and fob.
Owner of the franchise was good enough to add another key, another fob--the found keys.
They are charged, because the software that does the programming, is a subscription.
I watched the whole process, it takes time as there are built in wait periods. I took that to be in place so you cannot steal a vehicle using such a laptop and software, you're there for 5 min doing nothing but counting down...my .02
