HELP ! w/ 2004 Accent Alarm

Hi All,
Could use a little help....
I purchased a Crimestopper CS-2200. WST Keyless entry alarm system for a 2004 Accent 4 door sedan. Has anyone installed one of these or something like it successfully? Since you can, insert the Key turn it once to open the Drivers side and turn it twice to open all other doors, I figured all the hardware was in place & it wouldn't be too difficult to install the alarm. I'd appreciate any and all feedback on this. Thanks !
