clifford arrow

I just bought a used car with a clifford arrow alarm installed on by-pass. How do I determine which model arrow this is so I can purchase and program remotes?

Should be stamped on the alarm brain's casing. What does the part about by-pass mean? Rather confusing.

sorry, what I mean is it's in vallet mode with toggle switch. All it says on the body is "clifford arrow". it doesnt tell me if it is a 2, 3 or anything else

Turn valet off: Ign on, press star side twice, plain side once LED should extinguish. Unfortunately the last three models used the same Siren, unless you have a working remote, the answer stays the same as before. P.S. If you have a remote, silver colour is 5.1, black remote is the "Cello" versions 3 and 5. How old is the vehicle and what is it?

the remote I have is black with two buttons from an old clifford I had years ago.It is installed in a 94 acura integra

You could try it, alarm and valet off, ignition on, press star side twice, plain once, LED will flash, hold star for about 3 secs, siren will chirp, push plain once, chirp after 3 secs, push star once, immediate chirp, press lock/arm on remote, SHOULD get one chirp if it's compatible, press same button again, should get two chirps. Otherwise it's back to my first post.

P.S. If you have a RED LED it should be compatible.
