Don't know but have you looked in the owners manual ??? there is a plastic card that comes with the truck and the code is normally left in the manual...
Slightly fftopic: Keyless entry pad will work while vehicle is in gear and moving. Just wondered, so I reached thru window and "felt" my may to test it. Ok, now :back2topic:
Correct me if I'm wrong, but they don't sticker the code on the vehicle anymore. I bought a 2008 expy and I had to have the dealer retreive the code. No other way. 2007 may be different.
It appears the locks are controlled by the Smart Junction Box instead of a Security module as the Gen 1's were. Have no idea if they put the code on the SJB or not. Maybe L1Tech can advise. I just haven't worked on Gen 2's.
