Answer
You are correct, the 07' + Sierra's are
not easy to just "figure out".

There are only 2 solutions I know of to
bypass this one:

PLJX-UTI - Combo GM Passlock (ALL) +
Universal Transponder Bypasskit  
Combo GM Passlock (ALL) Resistance Override +
Universal Transponder Bypasskit. (70.00)

or the,

XK510 - Combo Platform 510: Upgradeable Door lock Interface + UTI
Firmware: GMDL6X 4.00 Combo Platform 510: Universal Transponder
+ Upgradeable Data Door Lock Alarm Interface. (70.00)

Aside from these 2 modules, you would have to
work out several relays and a few hours of wiring experiments
to get it to bypass effectively every time.

I do not have that method since it's very time consuming
and there are already bypass modules avail, so it's
either suck it up and get a module to do the bypass,
or invent your own solution for it.

Good luck.
