My MaxiDAS708 will code, my x431 will not, as nev says its not the person its the kit. Most mobile key techies use a keys only specific tool that does not do immobiliser, ECU and remote's. Just ask anyone you choose to use if they can do what you want them to do - and - if they won't charge you anything if they can't do the job you are paying for.

Yep, thats right, and don't be put off by "oh no it can't be done". A decent auto locksmith can and did do it. Once they had the pin number took about 10 minutes tops.
And my 2nd hand one works just fine on all functions.
 
My local shop-front auto locksmiths couldn't, they said it was a dealer only part and job.
 
In the same way that a tyre with a screw in the edge of the tread "can't be repaired" YES IT CAN. What they mean is we can't do it, because we don't have the ability to do a heat vulcanise repair. But most won't tell you the full detail and truth.

A good auto locksmith (not electricain) can program in a 2nd hand remote, I had one done, got it off ebay, and they should be able to cut a key with transponder and code it to the car as well.
They would need the pin number for the car to code in the remote, it's not the radio code.
 
There is a very good mobile guy near Manchester, but you don't say where you are
