All the cars are pre-wired for the alarm, but I believe it is a dealer installed option only. It's easy enough to install yourself if you want it.

UPDATE: I just noticed that my clown nose is flashing now (and my fog lights which didn't work before are now working) after installing my alarm. The alarm itself has still not been activated, but the clown nose flashing is a good start! For all I know, the alarm may work already, but I can't figure out how to set it off without breaking anything... Tried sitting inside and locking the doors and then opening them, but no luck. Tried also opening the hood when the doors were locked, to no avail. I think it really is not activated...
