Fiesta Remort Key Not Working

[fiesta0007]

dear friends

since last week my fiesta key not working

also open doors with manually

so do this

insert the ignition key and turn from position II (Ignition) to position 0
(All off) and back four times within three seconds.(do not start the
car).Remove the ignition key.The
locking control system is now in "learn mode" for the next 20 seconds
and the red warning system LED stays on continuously to indicate this.During the 20 seconds press one of the transmitter buttons.The
remotes signal and code number is learned by the locking module and is
indicated by flashing the warning system LED and sometimes also a beep.Wait until learn mode times out (20 seconds) or switch the ignition back to ON.
