My spare keys are in a realtor's box in my LP bay as well.. You need the magic number (Which is in my phone,, hidden) to get at the keys. I know where it's hidden.
Another item: Now as it happens I am a very good B&E Auto man, have managed to open many cars others could not... But Well.. I do not do that for a living.
But I have had a few I could not open.. one was a large, Chevy Pickup... So we checked with the local locksmiths and 80 bucks was just a tad pricey
So I took the owner to the local Chevy Dealer.. he handed over his Driver's license, His Registration (With the Vehicle Identification number) and a nice portrait of a dead president (President Jackson) and a short time later they handed him his license, registration two copies of a portrait of President George Washington, our first president, and a brand new key that fit perfectly.
Way cheaper than an 80 dollar locksmith.
