All locks are assigned a code at the factory. The code indicates the cut sequence for the key that operates the lock. If you know the code for your lock, we can generate a new key that matches the code. The cuts on the new key will be the same as the original factory key created to operate with your code. Codes can be found etched into the tailpiece of the door lock or on a small piece of paper stuck on the ignition lock. Pricing will vary for keys with cuts on one side or both sides of the key. Note that early keys are “single-sided” with cuts only on one side of the key, and later keys are “double-sided” with cuts on both sides. In order to make a key by code for a double-sided key, it will be necessary to purchase two key blanks. Comes with 1 aftermarket key. For additional keys, please update the quantity of choice.
