This CH series key code is used on BAUER LOCKS, YALE LOCKS, AMERICAN CRANES TRUCK TOPPERS and miscellaneous applications. If you are not sure if this is the correct key code for your application, start by comparing the key way (line art pictured in the image of this listing) with the face of your lock. It should match and this at least insures that the key blank used will fit in your lock. All keys are cut to the specific lock code shown here and are ready to work in your lock.
