What is the Scion xD stock alarm model ?
 

I'm looking to add a stock alarm to my 2009 xD that only has the keyless entry. I cant figure out what alarm model works with the stock keyless so I don't have to install a Aftermaket alarm.
I've installed a couple of aftermarket ones so I could go that route but I'd like to keep the key that has the remote from Toyota/Scion its 3 buttons one, one the has a unlock, lock and panic.
