The electronic key on your 2005 Ford vehicle syncs directly to your engine to start the vehicle. These keys are meant as an extra security measure to prevent non-programmed keys from starting the vehicle. While two keys are programmed by the dealership when the system is installed, you can program additional keys or replacement keys in just minutes at home.

Step 1

Insert your existing key into the vehicle's ignition and turn it to the "On" position then back to the "Off" position. Remove the key from the ignition.

Step 2

Insert a second working key, if you have it, into the ignition. Cycle the second key to "On" then back to "Off." Remove this key from the ignition.

Step 3

Insert a new replacement key into the ignition. Cycle the key to the "On" position and leave it there for one second before returning it to the "Off" position.

Step 4

Wait for the security light to turn on to indicate that the programming sequence has started.

Step 5

Leave the replacement key in the ignition for 10 minutes before removing it. After 10 minutes, the key will be programmed and ready for use immediately.

Step 6

Repeat Steps 3 through 5 to program any additional replacement keys.
