#65730309944 is for an alarm system.
#65730302424 is for an alarm kit.

When you look for the specific parts for the kit (I can't find a part #'s, just a listing) you get the following:

Control Module - $251.38
Ignition immobilizer Module $125.67
Inclination/motion sensor - $143.83
Siren - ? (no price listed)

The kit shown on Tischer shows a hood dead-man switch,sensor bracket, and alarm horn.

So, we have two kits. Hood dead-man switch and Siren/horn are common to both...so it looks like we have a chirp when the locks are ingaged/disengaged when installed and not activated. When activated the alarm will go off when trunk or doors are opended without remote key?

So...I agree that the chirp is worth the money and you get some theft protection if activated. The ignition kill and motion sensor would be nice adds but you pay through the teeth for both, and you will also need the command module.
