The factory alarm system installed by Toyota dealers on the 2000 4Runner Limited is the Vehicle Anti-Theft System (VATS). It is a passive anti-theft system that uses a special key to disable the ignition if it doesn't match the vehicle's security code.
Remote Controls:
The original remotes that work with the VATS alarm system are the two-button remotes with the Toyota logo. These remotes can lock and unlock the doors and trigger the panic alarm.
Reprogramming the Remotes:
To reprogram the remotes, you will need to follow the steps outlined below:
1. Insert the original master key into the ignition and turn it to the "ON" position. Do not start the vehicle.
2. Within five seconds of turning the ignition to the "ON" position, press and hold the lock button on the remote for at least two seconds.
3. The doors will lock and unlock to indicate successful programming.
4. Repeat steps 2 and 3 for any additional remotes you want to program.
Please note that these instructions are specific to the factory VATS alarm system installed on the 2000 4Runner Limited. If your vehicle has an aftermarket alarm system installed, the programming procedure may be different.
