Understanding the Immobilizer System and its Link to the Alarm

However, if there’s a problem with the immobilizer system, it can trigger the car alarm, leading to a double dose of trouble. Many modern vehicles integrate the immobilizer and car alarm systems, creating a complex interaction that can be difficult to diagnose. Sometimes, keyless car security problems can also be related to the immobilizer system.
