Flopshot: I was in the exact opposite fix. I wanted the alarm to get the window & vibration sensors. I happened to call a dealer in the SE Toyota region & they had one comming in the following week. I had been getting the run around from my local dealer for two months. They are not allowed to deal with SET dealers. Toyota of Boone had one that was comming in with everything but two options (alarm & locking lug nuts). I couldn't pass this one up.

The main reason I'm considering the factory vs aftermarket is the system integration (1 key fob & uses the same led)
