What is the keyless entry with the car immobilizer?
Immobilizers prevent the vehicle from starting unless the correct key fob is detected. Any car can have an immobilizer, but keyless entry cars especially need them. They don’t have the extra security of the key.
A car with keyless entry and an immobilizer means that the vehicle can’t be hot-wired and can only start if the person pressing the “start” button has the key fob in its vicinity. The key fob must send the correct signal to the immobilizer. Only then will it deactivate and allow the engine to start.
