Bought a Used Car with a Tracker Fitted: What Should You Do?

If you have bought a car with a tracker fitted, contact the tracker provider as soon as possible. You need to confirm which system is installed, whether the subscription is active, whether ownership can be transferred and whether the previous owner still has access to the vehicle’s location.

If you have bought a car with a tracker fitted, ensure to verify the tracker fitted system details to confirm its functionality.

Make sure the tracker fitted is registered under your name to avoid any inconveniences.

Do not assume the tracker is working simply because the hardware remains inside the car. The subscription may have expired, the account may still be registered to the seller, or the system may no longer be supported.

Key Takeaways

• Identify the tracker brand and model.
• Ask the seller to remove the vehicle from their account.
• Contact the provider and prove that you own the car.
• Check whether the subscription is active or transferable.
• Request updated installation documentation.
• Change passwords, contact details and authorised users.
• Confirm that the tracker meets any insurance requirement.
• Arrange a professional inspection if the system cannot be identified.

Why You Need to Check an Existing Tracker

A vehicle tracker normally has two separate parts:

1. The physical device installed in the car.
2. The customer account and monitoring subscription connected to it.

When you buy a used car, the tracker hardware will usually remain installed. However, the monitoring service does not always transfer automatically.

The former owner may have cancelled the subscription, or the provider may require you to open a new account. There is also a privacy issue if the car remains visible through the seller’s tracker app.

Until the provider confirms the account status, you should treat the tracker as unverified.

How to Identify the Tracker Provider

Understanding the importance of having a reliable tracker fitted is paramount when buying a used car.

Because trackers are installed discreetly, you may not be able to see the unit. Avoid removing dashboard panels or searching behind trim, as this could damage the vehicle’s wiring or interior.

Check the Vehicle Paperwork

Look through the documents supplied with the car for:

• An installation certificate
• A tracker invoice
• A subscription renewal notice
• A user guide
• A monitoring-centre telephone number
• An app name
• A serial number
• Driver-recognition tag instructions
• Details of the original installer

An installation certificate may show the tracker brand, product name, installation date and vehicle registration.

Look for Tags or Fobs

Some tracking systems use driver-recognition tags, cards or small fobs. These tell the monitoring system that an authorised driver is using the car.

Ask the seller whether any unfamiliar devices supplied with the keys belong to the tracker. Do not throw them away until the system has been identified.

Check Mobile Apps and Connected Services

Ask whether the previous owner used a tracker app or a manufacturer-connected vehicle service.

The car may need to be removed from:

• A tracker provider’s app
• The vehicle manufacturer’s app
• A dealership security platform
• A fleet-management account
• A shared family or business account

A manufacturer app is not necessarily the same as a professionally monitored security tracker, so confirm exactly which system is installed.

Ask the Dealer or Previous Owner

Request the following information:

• Tracker brand and model
• Name of the installer
• Monitoring provider
• Original certificate
• Subscription expiry date
• Driver tags or cards
• App details
• Confirmation that the seller has removed the car from their account

When buying from a dealership, ask the dealer to contact the previous keeper if the tracker information was not included in the handover.

Contact the Tracker Provider

Once you know the provider, contact its official customer-service team.

Explain that you have bought a used vehicle with one of its trackers installed. The provider may ask for the registration number, vehicle identification number or tracker serial number.

Proof You May Need

The provider may request:

• Your full name and contact details
• The vehicle registration
• The vehicle identification number
• A sales invoice
• The V5C or new keeper slip
• Photographic identification
• The installation certificate
• The tracker serial number

This process protects both the former owner and the new owner. Send documents only through the provider’s official channels.

Check the Subscription Status

A tracker may still be installed even if its monitoring subscription has ended.

Ask the provider to confirm:

• Whether the device is communicating
• Whether the subscription is active
• When the subscription expires
• Whether the existing plan can be transferred
• Whether you need a new subscription
• Which services are included
• Whether driver tags are registered
• Whether app access is available
• Whether the system requires testing or reactivation

Do not assume that any remaining subscription period belongs to you. Some plans are connected to the original customer rather than the vehicle.

Is the Tracker Working Without a Subscription?

That depends on the system.

Some trackers require an active subscription before monitoring, alerts or app access will operate. A device may still have power without providing a monitored security service.

Ask the provider to confirm the status in writing where possible.

Protect Your Location Privacy

A tracker can communicate the vehicle’s location, so it is important to make sure the previous owner cannot continue viewing the car.

Remove the Former Owner’s Access

Ask the provider to confirm that:

• The former customer has been removed
• Previous login details no longer work
• Old authorised users have been deleted
• Previous emergency contacts have been removed
• The vehicle is no longer visible in the seller’s app
• Shared access links have been cancelled
• Unwanted driver tags have been removed

Deleting an app from a phone does not necessarily close the account. The seller may still be able to log in from another device.

Create New Login Details

When your account is ready:

• Create a strong, unique password.
• Enable multi-factor authentication where available.
• Update the email address and telephone number.
• Change any account PIN or security questions.
• Review the authorised-user list.
• Check notification and privacy settings.
• Remove anyone who does not need access.

If the tracker includes an immobilisation-related feature, ask the provider or installer how overrides and authorised-driver recognition are managed.

Request Updated Documentation

Ask the provider whether it can issue updated documentation in your name.

Useful records may include:

• An installation certificate
• Confirmation of account ownership
• The tracker product name
• The tracker category
• The installation date
• Subscription confirmation
• The system reference number
• Theft-reporting instructions

Keep copies with your vehicle records, but avoid leaving sensitive tracker information inside the car.

Check Your Insurance Requirements

Do not assume an existing tracker automatically satisfies your insurer.

An insurer may require a particular tracker category, an active monitoring subscription and an installation certificate in the policyholder’s name.

Ask your insurer:

1. Is a tracker required for this vehicle?
2. Which tracker category is acceptable?
3. Does the existing tracker meet that requirement?
4. What documents are needed?
5. Must the subscription remain active?
6. Does the insurer need to approve a replacement?

Only provide information that has been confirmed by the tracker provider. Do not describe the system as active, approved or monitored unless this has been verified.

ome insurers may require a particular category of tracker. You can learn more about how vehicle-security products are assessed on the Thatcham Security Certifications page.

What If You Cannot Identify the Tracker?

Arrange an inspection with a professional vehicle-security installer.

Do not cut wires, disconnect modules or remove the device yourself. The tracker may be connected to the ignition, alarm, vehicle battery or CAN network.

A professional inspection may help establish:

• Whether a tracker is fitted
• Whether it is factory-installed or aftermarket
• Whether it is powered
• Whether the installation appears safe
• Whether tags or accessories are missing
• Whether it should be retained, removed or replaced

Ensure the tracker fitted system is capable of communicating effectively.

The installer may not be able to access the provider’s customer records, but they can inspect the physical installation and recommend the next step.

Should You Keep or Replace the Tracker?

Safe & Sound Mobile supplies professionally installed vehicle trackers, including S5 and S7 options from recognised tracker brands available through the website.

Nationwide mobile installation is available for suitable products, allowing professional fitting at an agreed home or workplace location.

Frequently Asked Questions

1. Can the previous owner still track the car?

They may be able to if the vehicle remains linked to their account. Ask the provider to remove the former owner and all previous authorised users.

2. Does the tracker subscription transfer with the car?

Not always. The hardware may remain installed, but the monitoring agreement may belong to the original customer. Contact the provider for confirmation.

3. How can I tell whether the tracker is working?

Ask the provider whether the device is communicating and whether the subscription is active. A professional installer may also inspect the physical installation.

4. Should I remove an unknown tracker?

Not before it has been identified. It may still be usable after the ownership transfer. If removal is required, use a professional installer.

5. Will the tracker satisfy my insurer?

Only your insurer can confirm this. Ask which tracker category and documents are required before relying on the existing system.

6. What if there are no documents or driver tags?

Contact the provider if you can identify the brand. If the tracker remains unknown, arrange a professional inspection.
