That may do the trick, or pulling the fuse & the relay for the alarm, but sometimes they wont start after doing that, alot of it is computer controlled and need the key fob to disable it. If you /her plan on keeping the car i would get another key from Toyota (quick) or even ebay (days,weeks). Or just call a toyo dealer (but its better to go in and talk with the "service writer") and ask him how to undo the alarm or set the code on the key fob if you get one from ebay.
