Toyota 4Runner 2022 Theft-deterrent system
The theft deterrent system is a complex web of security that is carefully stitched into the 2022 Toyota 4Runner’s fortress to keep out people who shouldn’t be there and protect this tough icon from theft. In addition to being good off-road and having a lot of different uses, this system is at the forefront of car security because it uses a mix of high-tech and mechanical safety features.

This detailed guide goes into the depths of this security network, breaking down the layers of protection and preventive measures that the 4Runner uses to keep both the car and the driver safe from theft and unauthorized access.
