which remote do i want

first i want to thank you all for some insightful answers to many questions that i didnt even have to ask but now i need to ask one

I  recently purchased a used truck from a dealer in chicago this truck i believe was purchased at an auction. now i have a truck with a clifford prime level4 alarm and an intellistart4 remote start system without a remote.I think the remote i want is just the typical prime level 4 replacement but i dont see a engine start buttyon on that remote if anyone could help with this i would greatly appreciate it

thanx a ton
