My TCH has the factory installed remote start.

I impress kids (and some adults) by pretending to start the car with verbal command. The factory remote start takes around 5 seconds to spool up after pushing the remote, which give me plenty of time to get my hands out of my pockets. So I push the buttons on the remote in my pocket, then take my hands out of my pocket and cup them around my face, and in a dramatic clearing of my voice say, "Toyota Camry start your engine!".

With proper timing the car will then immediately rev up.
