Programming / PATS Security
For Plug and Play you must do the following three steps:

Step 2: Please check with your mechanic regarding VIN programming as it may be required.
Step 3: If your vehicle has PATS security you must have your keys programmed. We recommend you have this done by your local locksmith.
