Car Alarms: Hi there. I see people sell..., alarm remotes, cpme

Question
Hi there. I see people sell 2 way alarm remotes by itself. What good are they, or they can be programed. If yes, does the remote type/brand matter?
Thank you,
John

Answer
From my experience, the trouble selling
the 2 way LCD remotes cpme in series and have
specific systems that they will work with.

If there is a 2 way remote sale, normally it
would need to be as a replacement for a certain
make and model.

I hope this helps.
