A:AnswerYes it fits. For some reason you can’t check on the app but if you look it up the product on a web browser, even a mobile one, you can check your car by year and model to see if it fits.
2001 Toyota Camry will work with this.
A:AnswerYes it will work but yes you will need to purchase a separate alarm. But for the price it's going for now I'd wait. I paid $249, if you wait for it to drop from the current price you should be able to get both for less. If you have push button start you can use the factory remote to start car as well, the range however will drop from 3000' to 500'.
