Will a Ghost Immobiliser Drain Your Battery

Will a Ghost Immobiliser Drain Your Battery

A valid concern when it comes to aftermarket security options for your vehicle, is whether or not they use additional battery power from your vehicle. This is a valid concern as it may mean you have to replace your battery.

In this blog, we will answer the question ‘Will a ghost immobiliser drain your battery?’

The UK automotive aftermarket industry is thriving, ranking fourth in Europe and ninth in the world in terms of size, and turning over an annual £21.1 billion.

The sector supports 345,600 jobs and contributes £12.2 billion each year to the economy. And it is growing: the sector’s value is set to rise to £28 billion by 2022.

That’s why we at Car Specialist Customs are here to provide you with all the information you require to get the best car customisation possible, whilst being as informed as possible.

Do cars have functions like a ghost immobiliser?

Modern cars do have some built-in security features that share similarities with a Ghost immobiliser, but they might not be as sophisticated or customizable.

Factory-Installed Immobilizers

Most modern cars come equipped with factory-installed immobilizer systems. These systems typically use a transponder chip embedded in the car key fob. The car’s ignition system is programmed to recognize the unique signal from the transponder chip.

If the correct key fob is not present, the engine will not start, even if someone manages to hotwire the car. It is similar to a Ghost immobiliser as both systems prevent the engine from starting without authorization.

Differences from Ghost Immobilisers

Factory-installed immobilizers often rely on a single signal from the key fob. A thief with specialized tools might be able to detect or bypass this signal.

Furthermore, factory-installed systems typically don’t offer the same level of customization as aftermarket Ghost immobilisers. Ghost systems can use hidden buttons, phone apps, or unique PIN code sequences for disarming, making them more difficult to bypass.

Additional Factory Security Features

Many cars come with factory-installed alarms that can be triggered by unauthorized entry attempts through doors, windows, or the trunk. This is standard amongst most if not all vehicles.

However, some high-end models might have built-in GPS tracking systems that allow authorities to locate the car in case of theft.

Will a ghost immobiliser drain your battery?

In normal operation, a Ghost immobiliser shouldn’t drain your battery significantly. It’s designed to have a low current draw, typically around 8mA. This is a very small amount of power and shouldn’t cause a battery drain on a healthy car battery.

However, there are a few situations where a Ghost immobiliser could potentially contribute to a battery drain:

  • Incorrect Installation: If the immobiliser is not installed correctly, it could draw more power than intended or cause electrical faults that drain the battery.
  • Faulty Unit: Like any electronic device, a Ghost immobiliser can malfunction and develop a fault that leads to increased power consumption.
  • Other Factors: If your car battery is already old or weak, even a small current draw from the immobiliser could contribute to draining it, especially if the car is not driven regularly.

Here’s what you can do to minimize the risk of a Ghost immobiliser draining your battery:

  • Ensure Proper Installation: Make sure a qualified technician installs the Ghost immobiliser according to the manufacturer’s instructions.
  • Consult a Professional: If you suspect a battery drain issue and think the immobiliser might be involved, consult a mechanic or auto electrician to diagnose the problem.
  • Regular Maintenance: Maintain your car battery by keeping it clean and free of corrosion. Additionally, consider replacing an old or weak battery to ensure it can handle the electrical demands of your vehicle.

Do other aftermarket security options use the car’s battery?

Yes, most aftermarket security options for cars rely on the car’s battery for power. Here’s why:

  • Constant Monitoring: Security systems need to be constantly vigilant to detect unauthorized entry or attempted starts. This means they require a power source to run their electronic components, monitor sensors, and trigger alarms if needed.
  • Power for Functions: Many aftermarket security systems come with features that require power. This could include:

Yes, installing a Ghost immobiliser typically requires specialized tools and knowledge.

The Ghost immobiliser needs to be integrated with your car’s electrical system. This involves working with wires, connectors, and potentially bypassing certain factory components.

Furthermore. a critical aspect of the Ghost system is its covert nature. The installer needs to strategically hide the control unit and various components within the car’s dashboard or wiring harness to prevent easy detection by thieves.
