Ford Focus Owners Manual: Coded keys

Note: Do not shield your keys with metal objects. This may prevent the receiver from recognising your key as a valid one.

Note: Have all of your remaining keys erased and recoded if you lose a key. Ask your dealer for further information. Have replacement keys recoded together with your existing keys.
