I assume the all-metal Ilco key doesn't have a transponder but opening doors will be good enough if the price is right.
Bunnings said nope. Seemed a bit thicker and longer than a car key even if they configured the machine for my benefit.
I assume those Westfield shoe repair/key cutters/fortune tellers will be cheaper than a locksmith but I was wondering if someone here has a specific place with a price. Years ago I read around $6.
Definitely go with the fortune teller.
