As some know. I do as much questioning and research before I post anything. In this post I believe I have information about the number of keys for the 37 812 cars.. Thanks to Wyn who has explained the key issues very well. Seems the passenger side door lock is the same key for the ignition, glove box and the gas door lock. The locking trunk latch has it's own key. So for the sedans we need two keys. I believe this is the same amount of keys for any 36 810 cars because those 36 cars did not have locking glove box doors.. I had new keys made for all of my locks on my 37 812 Beverly sedan because no keys came wit the car in 1961. Yesterday I worked in my shop trying all the locks to prove what I have posted here. This is another small piece of the treasures uncovered about these prized cars from long ago. Thanks again Wyn for your guidance.
