Hi all,

My first post on the board. This looks like a great place to learn a lot. I have searched the archives and cannot find anywhere this question may have already been posted.

We recently purchased a 2005 G3500 with one remote key. We bought a second one and have tried to progam it. Unfortunately, the instructions that came with it are for a 2001-2002 Chevy SUV (using the ignition on/off/on/off cycle) or 2001-2004 Astro (using the key in the ignition cylinder lock cycle), neither of which worked.

Any ideas how to get into programming mode in the 2005 Express? Any input would be appreciated.

Thanks in advance.

Detlef
