To tell if a vehicle has an immobilizer you can look on the dashboard for a possible immobilizer warning light or look into the owners manual or even contact the dealer or the car's or vehicle's manufacturer.
You can also tell if a vehicle has an immobilizer by wrapping your key in aluminum foil and if the car doesn't start when you try to start the car then the vehicle usually has an immobilizer.
Also if your car uses a key that has a plastic cover over it or a keyfob then it usually has an immobilizer.
Or if the vehicle is a newer vehicle then it also usually has an immobilizer as immobilizers are very common as a standard feature on new and modern vehicles.
Any vehicles that were manufactured as of October 1998 and onward often have vehicle immobilizers as a standard feature.
Your car or vehicle will have a factory installed immobilizer if the vehicle was manufactured after October of 1998.
But if your car or vehicle was made before October of 1998 then it may or may not have an immobilizer but contacting the vehicle's manufacturer and providing them with the VIN number can allow them to tell you if you have an immobilizer or not.
Remote immobilization on a vehicle is a telematics type of feature that allows an authorized person to remotely disable a vehicle's engine or critical functions, which can be done through a web app or mobile app, which can prevent it's theft or unauthorized or use even recover a stolen vehicle.
For example if someone took off with your car and your vehicle as the remote immobilization you can or the company can disable the car and stop it from going anywhere.
The remote immobilization shuts off and disrupts the fuel supply or ignition, which creates a safe stop for the vehicle.
The electronic vehicle immobilization system is also known as a passive immobilizer and is an anti-theft system that prevents someone from starting the vehicles engine without the correct keyfob or coded key.
In a vehicle with an electronic vehicle immobilization system the vehicle requires the correct key or keyfob that has a correctly coded transponder chip to communicate with the onboard computer of the vehicle to allow it to start.
If the correct security code is not recognized by the vehicle's computer system, then the start, fuel pump or ignition circuit will be cut off and disable the vehicle.
A passive immobilizer on a car is a an automatic and built in type of anti-theft system which prevents the car or vehicle from being started without having the correct electronic key.
A passive immobilizer on a car or vehicle doesn't require any manual operation and automatically engages when the engine is turned off and the car is secured.
The passive immobilizer system uses a transponder chip in the key which communicates with the car or vehicle's computer and then if the correct code is not detected it then disables the engine by preventing ignition or fuel delivery to the engine.
The vehicle' or car's key or fob contains the tiny transponder chip.
Once the key with the transponder is inserted into the vehicle's ignition, a nearby antenna then transmits the signal to the transponder chip to wake it up.
The transponder chip then sends back a unique rolling code.
Next the car or vehicle's onboard computer will verify the code and if the code is correct, the vehicle's ignition systems and fuel systems are allowed to turn on and work.
But if the code is not correct or the code is not detected, then the vehicle's computer will disable the engine and prevent the engine from running or starting.
The passive immobilizer on a vehicle is a common and standard feature in many modern cars and vehicles and it's primary purpose is to deter car thieves and make it harder for someone to hotwire or otherwise start the car or vehicle without having the proper key.
And for the most part the passive immobilizer system is invisible unless it has a malfunction or the key becomes deprogrammed and the system for the passive immobilizer is engaged automatically without any need to flip a switch or push any button.
