How reset ford transit key?

To reset a Ford Transit key, first ensure that you have two working keys. Insert the first key into the ignition and turn it to the "On" position without starting the engine for about 10 seconds, then turn it off. Remove the first key and insert the second key, repeating the process. This should program the second key to work with your vehicle. If you don’t have a second key, you may need to consult a Ford dealer for assistance.
