How do i disarm my lincoln continental 98 alarm?

What is your question?

My car overheated on me and i put a new water pump it has a new feul pump and a new radiator and new censors. It worked for like 2 days then it started overheating and i fixed the fans and once i did that i accidently took off y battery not knowing my alarm can lock and make my car not turn on. How do i unlock my alarm without the control and not mess everything up ease help and thank you very much.
