keyless entry?? questions

[jsplash88]

Hey guys,
I was wondering if anyone could help me with something I want to try. I have a 05 ford explorer sport trac exs. Basic truck has nothing but a/c and power locks and widows.
I am wanting to add the keyless entry and cruise control to it. I was thinking of getting the parts from a junkyard to do out. My main question is would I have to change the computer out for this. If anyone has any information please let me know. All advice welcome.
Thanks for looking,

the pcm can stay, you probably need wiring and the security module for the truck.

cruise control can be turned on or enabled in the pcm.
