I just bought a 01 Honda Accord and i just found out it has alarm system. But i do not have the remote, all i have is a key. i was wondering if i can just buy the remote or do i need to install the whole system. And also where is the alarm brain? Anybody please help me.

 

You have keys but you don't have remote. It is not easy to tell you that what you should do and all you need is to change the whole system and only i can suggest you this.
