How to Reset an Alarm on the 2000 Toyota 4Runner

by Katebo

Your 2000 Toyota 4Runner is equipped with an anti-theft system that is tied in with the power lock system. The alarm turns on when you power lock the doors using the keyless entry remote device. When you change the battery in your 4Runner, the alarm system automatically becomes disabled and needs to be reset. You can reset the alarm yourself from your home garage, saving yourself time and money.

Step 1

Put the 4Runner's key into the ignition and turn it to the "on" position. Find the valet switch near the hood release on the driver's side dash. Turn the valet switch on and off three times quickly. Listen for a short chirping sound coming from the alarm system.

Step 2

Press and hold the unlock/lock buttons on your keyless entry device. When you hear one long beep, release the buttons.

Turn the valet switch on and off again quickly. Turn the key in the ignition to the "off" position and then remove it from the ignition. Lock the doors using the remote to test the system.
