2007 Hummer H3 help reprogramming new BCM


Limo Guy

Question

Hi Guys, what's required to reprogramme a new BCM on a h3?

 

I have access to a tech2 machine with the correct memory card, do I also need a security code? If so how can I find this, I didn't get it when I bought the car. I'm in the UK and no dealers here.

 

Or does the hummer require security software?

 

Thanks

A Vauxhall dealer should be able to help you

Isn't there a way to do that via a GM website and a J2534 interface? Thought you just pay the fee on the site, and then download the program? I'm new to all this stuff, so I'm sure it's not this simple ....

No. I know the updates and programming needs to be done by a dealership with GM licensing in their system. Some shops may be able to, but a GM dealership is your best bet. Normal going rate here is about $95 or 65 Pounds
