P38A testing the transmitter

I realise that there are people who can do it. Thats why I said without sending it away

They might share how they do it. Marty has a board he made up with a couple of LEDs, iirc. It plugged into his laptop and that decoded the signal I think. Easier to just post it down I would imagine.
 
I only have the one key. I am trying to get a valet key cut so I can still use the car then, if the old fob is working,I will have a new one made, thanks
 
ok, thanks, I will look int this and see if I can work out how to do that. Once I can establish that the key is working I can test the other bits and replace the faulty item
 
As Grrrr mentions - I have a fob tester to be able to read/check the fob code being transmitted from the key fob. Without having the BECM aswell though, I wouldn't be able to tell you if it's the same code as is stored in there though.

But unfortunately it isn't easily possible to do at home at the moment!
