07 Tahoe LTZ Keyless Entry and Key Programming Question

2007 Tahoe LTZ with remote start and power lift gate. I just purchased a 6 button key fob (15913427) and a blank key (692931). Is this something the dealer has to program or can I do it from instructions somewhere? I only have 1 original key and fob. Please let me know.
 
Thanks,
Shane

I checked them and they didn't have 2007.  Only went up to 2005.

Thanks Guys, Found the instructions and will try and repost my results. Still open about the key though.

On my replacement key, all the dealer did was put the start the car with the good key, then shut it off and put the new key within 10secs and started the motor, which programmed the new key.

Great info.
 
Thanks!!!

Everything programmed well with the key as well as the fob. I didn't realize but in my 07 user manual is the programming instructions also. I couldn't believe it.
 
Thanks for your help,
Shane
