I can't recode the central locking

[Titan]

I'm trying to recode the central locking module on a 2002 model.
The current code is 15179 and I would like to add the following;
+00004=selective locking
and
+00032=locking via speed
When I try to change the code to 15215, I click on 'Go for it' and it takes me back to the main central locking module screen but the original code remains.
I've tried just adding 4 and then just adding 33 but to no avail.

I do have an error code for the alarm which re-appears as soon as I clear it so I wondered if you maybe cannot recode when there is a fault?

Any help would be appreciated.
Thanks.

1st thing- standard coding should be 15178 so try adding to that instead of 15179.
Otherwise check COM port latency setting, it was 5 or 10ms by default on mine and it was really difficult to reset service remainder took like 10 tries to get it done. Then I read somewhere that you should change latency to 1 or 2ms, I set it to 1ms and it works fine every time. Some of the cheap e-bay cables might not work with 1ms but all should with 2ms.

Thanks for the info. Much appreciated.
It will probably be the weekend before i get a chance to look at this again.

I did some other digging and now wonder if I'm being stupid and have a conflict between settings?
I'm trying to add in the code so that I have one press of the key fob to unlock the drivers door and a second press to unlock all the doors for security reasons.
What I didn't do was take into account the code that's currently set to one press unlocks all doors.
If this turns out to be the case, you'll probably find me in B&Q looking for a tin of tartan paint..........

I just recoded mine, it was 15179, vcds says add 32 for locking at speed, recoded it to 15211, I havent been able to test it yet, will let you know tomorrow.

I couldn't wait till tomorrow ,i had to go test it now, it locks around 15MPH, and unlocks when the key is pulled out,Thanks lads I have wanted to do that for years just didn't know how to..... Next step I want to code the honk of the horn on locking/unlocking, anyone know how to?

now that is very handy, i have been meaning to do this for some time, i also would like the honk of the horn when the car is locks to confirm locking as the clear indicators are not always that easy to see when its sunny
