On 1935 to 1966 Briggs & Stratton locks used by GM (B-10 and B-11 
typical keys) there are 6 tumblers and 4 depth positions.  So Padgett is 
right, there are in theory 4 to the 6th possibilities (4096). In 1967 
the A B C D  series of keys (B-45 B-46 etc) started and these had 5 
depths of cut. So now we have 5 to the 6th  (15,625) possibilities. 
Glove box locks did not always have 6 tumblers.  They are a less secure 
lock. And not all possibilities were used, such as in a key cut to all 
depth 5. From 1935 to 1966 only 1500 key combinations were used. In 1967 
there were 1000 key combinations for the A  (B-48) key and 1000 
combinations used for the B (B-49) key. Again 1000 for the C & D for 
1968 and E & H for 1969. Now if I just knew how to do exponents in 
e-mails....
