Remote Keyless Entry?

[cekkk]

I'd like to get a 2nd remote for my DW. The key shop we use for the ranch wants over a hundred bucks, most of which is to program the thing. Is this something I can do if I purchase just the remote? Or am I stuck paying $65? It's like this one:
2014 OEM GM 6 Button Keyless Entry Remote w/ Remote Start - OUC60270, OUC60221

Similar question about ignition keys. With some of my previous cars, a combination of honking the horn and turning ignition on and off could program one. Is that feature available on this 2014 Yukon Denali EL?

Your owners manual will tell you if it can be programmed or not.
