Engine Immobilizers: How They Work and Why You Need Them?

Engine Immobilizer

In this blog post, we’ll take a closer look at what engine immobilizers are, how they work, and why you should consider getting one. As vehicle thefts continue to rise in such countries, vehicle owners are increasingly looking for ways to protect their fleets. One of the most popular methods of deterring theft is through the use of engine immobilizers. 

What is an Engine Immobilizer?

An engine immobilizer is a security device that prevents your car’s engine from starting unless and until the correct key or fob is present. It does this by disabling one or more components of the engine management system, such as the fuel pump or starter motor. Without these components, the engine cannot start, even if the thief manages to get inside your vehicle.

There are two main types of engine immobilizers: mechanical & electronic. Mechanical immobilizers are physical devices that prevent the steering wheel or gearshift from moving. Electronic immobilizers, on the other hand, use advanced electronic technology to prevent the engine from starting.


How Does an Electronic Engine Immobilizer Work?

Electronic engine immobilizers are the most common type of immobilizer in modern fleets. They use a small transponder chip embedded in your vehicle key or fob to communicate with the fleet’s engine management system. When the key is going to insert into the ignition, the transponder sends a unique code to the engine management system. If the code is correct, the engine management system allows the engine to start. If the code is wrong or missing, the engine management system disables the engine, preventing it from starting.

Electronic engine immobilizers are highly effective at preventing car theft because the transponder chip is virtually impossible to duplicate. Even if a thief manages to gain access to the car and hotwire it, the engine will not start without the correct transponder code.

Our GPS tracking software includes features such as remote engine shutdown or immobilization. This allows the owner or fleet manager to remotely disable the vehicle’s engine if it has been stolen or if it is being operated outside of authorized hours or locations. They can quickly and easily locate their vehicles if they are stolen or lost. Additionally, the software can be used to set up geofences, which are virtual boundaries that trigger an alert if the vehicle enters or exits a specific area.

By combining GPS tracking software with an engine immobilizer system, vehicle owners or fleet managers can have a comprehensive security solution for their vehicles. The GPS tracking software provides real-time monitoring & alerts, while the engine immobilizer system prevents the engine from starting without the correct key or fob. Together, these systems provide a powerful solution against vehicle theft and unauthorized use.


Benefits of Engine Immobilizers

The primary benefit of an engine immobilizer is that it effectively reduces the risk of car theft. Even the most determined thief will be unable to start the car without the correct key or fob. This not only protects your car from theft but also your personal safety. Carjackings are the most serious problem in some areas. Engine immobilizer can prevent a thief from stealing your fleet while you’re still inside.

Another benefit of engine immobilizers is that they can lower your car insurance premiums. Most insurance companies offer discounts for cars that are equipped with immobilizers because they are less likely to be stolen. This can save you hundreds of dollars per year on your insurance premiums.

Finally, engine immobilizers are easy to use and require no special training and maintenance. Once the immobilizer is installed, all you need to do is carry the correct key with you when you drive. The immobilizer will automatically activate when you turn off the engine. With this you don’t need to worry about remembering to turn it on or off.
