What causes a car to go into anti-theft mode?
A car can enter anti-theft mode for a variety of reasons, typically as a security measure to protect the vehicle from theft or unauthorized access. This mode is designed to disable certain functions of the car, making it more difficult for someone to start or operate the vehicle without the proper keys or authorization.
Reasons a Car May Enter Anti-Theft Mode

- Tampering with the Vehicle - If the car's sensors detect any unauthorized entry or tampering, such as someone trying to break into the vehicle, the anti-theft mode may be activated.
- Low Battery in Key Fob - A low or dead battery in the key fob can sometimes cause the anti-theft system to engage, as the car's computer may not be able to properly authenticate the key.

When a car enters anti-theft mode, it typically disables the engine, prevents the doors from being unlocked, and may even activate the alarm system. This is done to deter potential thieves and protect the vehicle until the proper key or authorization is provided.
Resolving Anti-Theft Mode
