Programming / PATS Security
For Plug and Play you must do the following three steps:
Step 1: Match your part number per above fitment/interchange notes
Step 2: Program ecu to your VIN. Your local certified mechanic can perform this task and in some cases even your local traveling locksmith can handle this task!
Step 3: If your vehicle has PATS security (Most Ford/Lincoln/Mercury's do) you must have your keys programmed. We recommend you have this done by your local locksmith. In most cases they will travel to your location and the process takes less than 30 minutes. No towing necessary and your local locksmith will be cheaper than a dealer.
- Pins perfect, none are broken or bent
- Mounting points good
