Clifford cz57rrko remote
 

i have a clifford matrix rs alarm already installed in my car when i bought it,(its a 1997 nissan sentra)
the remote that came with it i think is broken it has the fcc id cz57rrko I bought one off of ebay and i want to know how to program it. I look under the drivers side and I've found my valet switch and saw the alarm black box it says matrix rs
