Hi tshardeb! If you don't have the owners manual handy you may want to talk to the service manager of your local Toyota dealer. Chances are that once you give your VIN# and/or establish ownership, the dealer will give you the sequence needed to reset the anti-theft system. Hope that helps. Good luck!

dealership if you cant do it your self. Usually this happens with aftermarket alarms. Disconnect the battery unlock or lock the car, the alarm sould still work for 20 seconds. connect the battery and lock/unlock the car. Just do variations of locking and unlocking the car because every alarm system is different so i dont know the 100% procedure. This this a couple of time just play with the alarm remote. If you dont have the alarm remote GL!

I had the same problem. With my car we found that you have to have the hood, trunk and all the doors closed before you can start the car. In our case, we took the battery out and charged it, then put it in and closed the car and started it.
