After going snowmobiling in - 26° F and losing my only set of keys to my 68 Barracuda when I was young, I learned to always carry two sets of keys at all times....
A soon as I get a car, I go get at least 4 - 5 sets of keys made... Two to keep on me, one spare key for the key drawer, and a master key...
Duplicate keys are much cheaper than having a car re-keyed... (cheap insurance...)
