I hope you are getting this remote starter installed at a certified installer (and definitely not Best Buy).
I love my 2-way CompuStar remote, but next time, I will probably just get the 1-way (smaller fob), and use their internet module so I can manage the car using my Android phone.
One thing I did do was replace my Toyota key with a key which doesn't have the fob integrated, which cuts down on the bulk of your keychain (my US 07 doesn't have PATS).
