If you own a Toyota car and ever lose your keyless remote entry controller, you can run into problems with the alarm system. If you replace the battery, the alarm system will be activated and you will not be able to start the car again until the alarm has been disabled. There is a simple fix for this that will allow you to turn the alarm off and start your car again without using the keyless remote.

Step 1

Insert the key in the ignition.

Step 2

Turn the key quickly from the "Run" position to the "Off" position five times.

Turn the key to the "Start" position and start the car. This will disable the alarm and allow you to start the car again.


  • This method will only work for disabling the alarm on Toyota cars.
