You can program additional keys into a Ford Puma from 1998 to 2002 using a manual procedure. To do this you must be in possession of a red master key that starts the vehicle.
The key programming procedures are available here:
Ford Puma 1998-2002 key programming
If you do not have a red master key then a diagnostic machine plugged into the vehicle will be required.
Alternatively... if a key that starts the vehicle is brought or sent to us we have the facilities to copy the transponder chip within it onto a new one. The new key will then start the vehicle without any further programming being required. Email us at firstname.lastname@example.org for further information.
