I've got an ed fairmont.
i bought it with keys, but it has no smartlock buttons.
I've got a couple of old smartlock buttons laying around, and i know you can make them work.
How do you make them learn the code?

Adding and Removing remote Keypads to the Smartlock module:

1. The ignition switch should be in the Off position, with all the doors shut and Unlocked.
2. Turn the ignition key to the ACCESSORY position and within 5 seconds, operates the boot release switch exactly three times in quick succession.
3. After the 5 seconds is up, the door locks will change state, to indicate that the Smartlock module has entered keypad learn mode.
NOTE : All existing keypads at this point, have been erased from memory !
4. Press either buttons on the keypad that is to be trained. The door locks will change state twice, to indicate that the keypad has been added to the Smartlock module memory.
5. Follow step 4. for each keypad that is to be added to the Smartlock module memory. A maximum of 4 keypads can be added to the Smartlock module memory.NOTE : You must teach all remote keypads for the Smartlock module, before proceeding.
6. When you have taught all the remote keypads, turn the ignition to the Off position to leave the learn mode. The door locks will change state to indicate a return to normal mode.
7. Check the function of both buttons on each keypad, to ensure that the keypad has been trained.

The above is for EBII - ED, EF & EL are same, except use the demist button.

yeah that worked, cheers.
i also found out that the procedure is in the owners manual.

No probs - yeah there's a few places you can find this - my reply was just a cut & paste from the EF/EL doco + a few words added.
