Why are my car keys in the freezer?

When you put your car keys in the freezer does it mean:

a. You are overworked
b. You are overwhelmed
c. You've found the perfect spot to store car keys that you'll never forget
d. You are an author struggling to work out a scene in your head

I am thinking...hmmm...all of the above. But I do now know that electronic key gadgets; you know the keyless keys, will survive at 30 degrees.
