The key code can be obtained from the 4-digit number on the key tag that accompanies the original master and valet keys. The 4-digit key code cross references to the cut and tumbler sequence. The keys have 10 key cut positions and 4 key cut depths. Key cut positions are numbered 1-10, counting from the head of the key to the tip. The key cut depths are 1-4, cut depth number 1 is the deepest cut. The key transponder in the master and valet key must be programmed to the vehicle. Refer to Programming Theft Deterrent System Components in Theft Deterrent.

Cut a blank key with the proper position and depth according to the tumbler sequence in the lock cylinders or to the key code on the original key.
Inspect the mechanical operation of the duplicated key in the front side door lock cylinder and the ignition lock cylinder to ensure proper fit and function.
When replacing or duplicating a key, program the key transponder to the vehicle. Refer to Programming Theft Deterrent System Components .
