keyless entry

i need one for my truck and my wifes any suggestions? no remote start just keyless entry maybe roll windows up and down

stock keyless entry just needs a keyfob for doorlock and have fob programmed to existing module in truck, especially if you have a OBS XLT

thanks omd,

any leads on where to find the stuff? yeah my truck is a xlt, is it the same on the superduty?
