How do you program a new replacement key for a Ford Escort?

Answer 1

for Ford keys (1996 -early 1998 )
The red master key is needed for programming extra keys, if no red master key is available one will have to be made, after buying a new uncut red master key with new transponder chip and getting the keyblade cut for your locks you can follow the below instructions for in car programming.
(carrying out this procedure is at your own risk as all keys are erased in the process)

If you want to initiate a new red master key....

1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.

2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.

3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.

4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.

If you want to add an extra key....

1. Insert an existing key into the ignition cylinder.

2. Turn the ignition cylinder to ON (RUN) and back to OFF.

3. Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN).

4. The security light will light up for two seconds to indicate success in programming the key into the vehicle.

5. Don't attempt to start the vehicle with any key for at least 1 minute.

There is a mode in the car's computer which can allow you to program an extra key without the need for a red master key, using diagnostic equipment, this only works for cars which haven't had this option disabled.
