Installing additional security is one of the most effective ways to protect a modern vehicle from key cloning, relay attacks and other electronic theft methods. However, many drivers understandably want to know whether fitting a Ghost Immobiliser could affect their manufacturer’s warranty, insurance policy or vehicle finance agreement.
The short answer is that a professionally installed Ghost Immobiliser is designed to integrate discreetly with a vehicle’s existing electronics. However, warranty conditions, insurance policies and finance agreements can differ, so it is important to check the requirements that apply to your particular vehicle.
Here is what you should know before arranging an installation.
What Is a Ghost Immobiliser?
The Autowatch Ghost-II is a discreet vehicle security system designed to prevent an unauthorised person from driving your car.
Rather than relying on a traditional key fob, the system requires the driver to enter a personal sequence using existing buttons inside the vehicle. These may include controls on the steering wheel, dashboard, doors or centre console.
Without the correct sequence, the vehicle cannot be driven normally—even when someone has obtained the genuine key or intercepted its signal.
Unlike many traditional security products, a Ghost Immobiliser does not use an additional radio-frequency key fob or an obvious LED indicator. Its discreet installation makes it difficult for thieves to identify and attempt to bypass.
You can learn more about the system on our Ghost Immobiliser installation page.
Will a Ghost Immobiliser Void My Car Warranty?
A Ghost Immobiliser does not automatically void an entire vehicle warranty.
Autowatch describes the Ghost-II as a security enhancement designed to integrate with a vehicle’s existing systems. Nevertheless, warranty terms can vary between manufacturers, dealerships and third-party warranty providers.
A manufacturer would generally need to establish that an aftermarket component or its installation caused the particular problem being claimed before refusing warranty coverage for that repair. This does not mean every installation is treated identically, which is why professional fitting is so important.
An incorrectly installed electrical accessory could potentially cause faults or create a warranty dispute. Drivers should therefore avoid attempting a DIY installation or using an installer without suitable knowledge of the product and vehicle.
If your vehicle remains under warranty, you can take the following precautions:
- Use an experienced professional installer.
- Check that the system is compatible with your make and model.
- Keep your installation invoice and supporting documentation.
- Ask your manufacturer or dealership for confirmation if warranty status is particularly important.
- Tell the installer about any existing electrical faults before work begins.
SecureAid checks vehicle compatibility and installs the system discreetly to minimise interference with the vehicle’s normal operation.
Should I Tell My Insurance Company?
Yes. It is sensible to tell your insurer whenever an aftermarket security system is installed.
Although a Ghost Immobiliser is intended to reduce theft risk, insurers have different rules regarding vehicle modifications and security devices. Informing the insurer ensures that the information attached to your policy remains accurate.
Do not assume that installing an immobiliser will automatically lower your premium. Some insurers may view additional security positively, while others may leave the price unchanged.
The result can depend on:
- Your insurer and policy terms
- The make and model of the vehicle
- Where the vehicle is normally parked
- Local vehicle-theft risk
- The insurer’s approved security requirements
- Whether a tracker is also required
For high-value or frequently targeted vehicles, an insurer may specifically request a Thatcham-certified S5, S5+ or S7 tracking system. A Ghost Immobiliser and an insurance-approved vehicle tracker perform different functions, so one should not automatically be treated as a replacement for the other.
Is a Ghost Immobiliser Thatcham Approved?
The Autowatch Ghost-II is described by its manufacturer as TASSA verified. However, this should not be confused with the separate Thatcham certification categories used for certain alarms, immobilisers and vehicle tracking systems.
If an insurer has requested a particular Thatcham category, ask them to confirm exactly what must be installed before making a booking.
SecureAid supplies and installs insurance-approved vehicle trackers, including S5, S5+ and S7 systems. These can be combined with an immobiliser to create a stronger, layered vehicle-security setup.
Can I Install a Ghost Immobiliser on a Financed or Leased Car?
In many cases, additional vehicle security can be fitted to a car purchased through hire purchase or personal contract purchase. However, the finance provider remains the legal owner under certain agreements until the final payment has been made.
Your agreement may contain rules about modifications, so it is worth checking the terms or contacting the finance company before installation.
The same applies to leased vehicles. Leasing companies can impose stricter conditions and may require written permission before an aftermarket product is fitted.
Ask the provider:
- Whether additional security devices are permitted
- Whether prior written approval is required
- Whether the system must be removed before the vehicle is returned
- Whether installation documentation must be supplied
Getting confirmation beforehand can help prevent disagreements when the agreement ends.
What Happens When My Car Goes for a Service?
The Ghost-II includes a Service or Valet Mode that temporarily suspends the normal disarm requirement. This allows a garage, dealership or valet to move the vehicle without being given your private PIN sequence.
Your installer should demonstrate how to activate and deactivate this mode after fitting the system.
You should never write your PIN inside the vehicle or disclose it unnecessarily. If the vehicle is being serviced, use the designated service mode and check that the immobiliser is operating normally when the vehicle is returned.
Can a Ghost Immobiliser Be Removed?
A Ghost Immobiliser can usually be professionally removed if you sell the vehicle, return a leased car or decide to transfer the system to another compatible vehicle.
Removal should always be handled by a suitably experienced installer. Attempting to locate or disconnect the system yourself could damage the vehicle’s wiring or create electrical faults.
Compatibility should also be checked before assuming the same unit can be transferred to a different vehicle.
Does a Ghost Immobiliser Include Tracking?
No. A Ghost Immobiliser is primarily designed to prevent an unauthorised person from driving the vehicle. It does not provide live location tracking by itself.
A vehicle tracker serves a different purpose. Depending on the system selected, it may offer:
- Live GPS location information
- 24-hour monitoring
- Movement or theft alerts
- Driver-recognition tags
- Support with stolen-vehicle recovery
Drivers who want both theft prevention and recovery support may benefit from installing an immobiliser and an appropriate insurance-approved tracker.
Why Professional Installation Matters
Modern vehicles use complex electronic networks. Installing a security device requires knowledge of both the product and the vehicle in which it is being fitted.
Professional installation helps ensure that:
- The system is suitable for the vehicle.
- Connections are completed correctly.
- The immobiliser remains discreet.
- Normal vehicle functions continue to operate.
- You understand the PIN, override and Service Mode procedures.
- Appropriate installation records are provided.
Choosing an installer solely on price could lead to problems if the product is incorrectly fitted or aftercare is unavailable.
Modern thieves may also attempt to exploit a vehicle’s internal electronic network. Read our guide to CAN bus car theft and how to protect your vehicle for more practical security advice.

Frequently Asked Questions
Does a Ghost Immobiliser invalidate a vehicle warranty?
It does not automatically invalidate the entire warranty. However, warranty conditions differ, and problems caused by an aftermarket product or poor installation may not be covered. Use a professional installer and check with the manufacturer when necessary.
Do I need to declare a Ghost Immobiliser to my insurer?
You should inform your insurer after fitting any aftermarket security system. They can confirm whether it affects your policy, premium or security requirements.
Will a Ghost Immobiliser reduce my insurance price?
It may be viewed positively by some insurers, but a lower premium is not guaranteed. Pricing depends on the vehicle, driver, location, insurer and policy.
Can I fit a Ghost Immobiliser to a financed vehicle?
It may be possible, but you should check the finance agreement first. Some providers require permission before any aftermarket equipment is fitted.
Is a Ghost Immobiliser the same as a tracker?
No. An immobiliser is designed to stop the vehicle from being driven without authorisation. A tracker helps locate and recover a vehicle if it is stolen or moved.
Can a garage service my car after installation?
Yes. The Ghost-II includes a Service or Valet Mode, allowing authorised technicians to move the vehicle without learning your private PIN.
Can the immobiliser be removed before selling the vehicle?
It can generally be removed by a professional installer. Do not attempt to disconnect it yourself, as this may damage the vehicle’s electronics.
