What is this key for?
 

I will try to do this without a picture. I have a 85 300tdt, new to me. It came with 2 ignition keys plus a 3rd small key in a little plastic baggie. The key is ,well, key shaped, about 1 inch long but without the typical serrations of a regular key. It is steel, kind of looks like a slug, just stamped out of a piece of metal

I bought the car sight unseen, never talked with the original owner, bought it through his mechanic.

the flat key?


it's a wallet key, incase you've locked your keys in the car. it will only open the doors.

I thought the flat key and master key were equivolent except for one being flat to fit in your wallet.

En doing a search, this is all I could come up with:

The types of keys are:
Master - Full-sized, opens everything
Valet - Full-sized but with a round head, does not open glovebox/console nor trunk, if trunk's fully locked (all the way clockwise)
Wallet - small head, opens everything
