Re-keying locks
Lock cylinders cannot be ordered by specified key numbers. On most cars one-key convenience can be retained by changing the appropriate lock tumblers to match the key that is going to be used.
Note
Tumblers in the ignition lock cannot be changed.
On certain older vehicles, the glove box key is different than the ignition key. A separate kit is available from the Parts Department to change this lock.

^ the plastic plate that comes with the original set of keys
^ recorded by owner or selling dealer in vehicle owners manual

The code in catalog is listed in following sequence:

4-3-4-1 -3-4-1
3 1 3 2 3 1 3 = tumbler arrangement
1 1 according to code list
+ 4 1 4 2 3 1 3 = tumbler arrangement of converted lock cylinder

Lubricate the tumblers and springs with G 000 400 grease or equivalent as they are inserted into the lock cylinder.
^ reading key code numbers from left to right, insert tumblers in the lock cylinder housing starting at the key slot

When working with a lock cylinder with only 5 tumblers, use tumbler number sequence minus the first two tumblers.
