That procedure looks about what I used...
OK. I've just tried that lot and didn't even get past the first hurdle; programming the remote. I've highlighted the bits which aren't clear. Perhaps someone who's done this can advise:
*Please program remote first before cutting key --why does this matter? My key has already been cut by the looks of things
- Remote Programming Steps:
1.Program remote once received (Central locking will work now)
2.Take key to locksmith shop and get them to cut your key to code
3.Program transponder chip (this will now start car)
- Remote Programming Procedure:
1. Open Driver side door
2.
Put the Original key in and out of ignition 2 times --I'm just putting the key in and taking it out twice. Not turning the ignition to ACC or ON or anything?
3. Close and open driver door 2 times
4. Put Original Key in and out of ignition once
5. Shut and open door twice
6. Close door
7.
Insert key Turn ignition on --is this the original key or the new one?
8. Turn ignition off and remove key
9. Door locks will cycle
10.
Press lock and unlock together for 1 second then lock button --on the original key or the new one?
(To delete remotes turn the key on and off 5 times, door locks will cycle 5 times. Turn the key on then off. Open shut door)
11.
Locks will cycle put key in ignition turn to on then off --new key or old one?
12.Remove key from ignition, close door and test remote
<snip> The rest is about programming the key itself. But I've not even got that far!
EDIT: I've just tried again, substituting the new key for all the steps in red above, where it wasn't specified which key was being referred to. Still no joy. At step 9, the door locks don't cycle. Incidentally, my spare key does unlock the ignition, as in I can turn it to ON and the dashboard lights up. But I'm presuming the truck will refuse to start because of the immobiliser. I didn't want to try that before consulting the forum, in case it completely fecks up trying to pair that key and makes he truck go into lockdown mode. Last thing I need is Boris Johnson turning up to tell me to 'stay safe'.
