Many models of Ford vehicles feature ignition keys that are attached to wireless remotes. These keys can flick inside and outside of the handheld remote and are used like a normal key to start your car. Ford switchblade keys can be programmed electronically to your engine for security. These keys are known as transponder keys, and you can get them working by yourself, without the help of an expert or mechanic.

Skill level:
Moderately Easy


  1. 1

    Provide your key code to a locksmith and get a new key made, or get a key from your Ford dealership.

  2. 2

    Sit in the driver's seat of your Ford car. Insert your key into the ignition.

  3. 3

    Turn the key to the "On" position. Leave the key in the "On" position until the security light on the dashboard turns on and begins flashing. Wait for this light to stay on and flashing for 15 minutes before proceeding.

  4. 4

    Turn the ignition back to "Off" once the light stops flashing.

  5. 5

    Turn the ignition back to "On" again and wait another 15 minutes for the light to start and then stop flashing. Repeat this process one more time, allowing the light to turn on for 15 more minutes. This will make a total of three cycles, and you can end with your key in the "Off" spot.

  6. 6

    Turn the key to "On" again and the security light will not be flashing anymore. This will indicate that the programming worked and you can remove the key and use it as usual.

  7. 7

    Program a second transponder key by first inserting your working key in the ignition. Turn the key to "On," then "Off," and remove it. In less than five seconds, insert the new key. The security light will come on for two seconds to show that the new key is programmed.
