For select 2000s Toyota, Lexus, and Scion models, a VIP Remote Engine Starter was available as an add-on accessory.
This system integrates with the keyless entry, utilizing the lock button for control.

Warning sticker applied to the underside of the hood:
If you enter your VIN on the Toyota Owners VIN lookup site, you'll see this listed in the PORT OR FACTORY INSTALLED EQUIPMENT list:
Or at least you used to be able to. Toyota recently overhauled their website, which locked the VIN lookup to only users with Toyota Owners accounts. Even after logging in, some of the functionality seems to have been broken. No matter how many port or factory installed equipment a vehicle has, the website you only show you one, and usually the last in the list. I tried telling Toyota about this issue, but either I wasn't clear enough in my wording or they just didn't understand, the issue never got fixed.
To remote start the engine, press the lock button on the key fob two times, and then hold on the last press. This starts the engine. Note that once any door is opened, the engine shuts off as a safety measure.
