security system

So much to my enjoyment I found that my element had both an alarm and CD changer that the dealer neglected to mention to me.... heres the problem I threw my keys at an ex and broke the clicker, (cars still around she isn't) where can I get a new one and (about) how much are they ....:cool:

Hello everyone, I took ownership of a used 2004 Element. Seems like a great car, but after looking around the interior, I found that the vehicle has an aftermarket security system. And now my question, does anyone have a user manual for a KARR 2040a security system? I didn't get any remotes...
