You can usually move a Thatcham tracker to a new vehicle, but not as a quick swap. Treat it as a fresh professional installation: the tracker is removed, refitted and tested on the new vehicle, your insurer is told and the monitoring account is updated to match. The cost of that work is the part most buyers miss, so ask the installer to confirm it before you sell or replace the old vehicle in 2026.
- Moving a Thatcham tracker to a new vehicle means professional removal, refitting and testing, not a self-fit swap.
- Tell your insurer before the old vehicle leaves your fleet and confirm the new vehicle is covered.
- S7, S5 and S5 Plus differ in function, so check the fob and immobilisation after any move.
- Monitoring is separate from the tracker, so the account must follow the tracker to the new vehicle.
- Ask your installer in writing what a transfer involves before you commit to the change.
Why moving a tracker matters in 2026
A Thatcham-approved tracker is not a plug-in gadget. It is installed into a specific vehicle, tested there and monitored against that vehicle's details. If the vehicle changes, the record behind the tracker has to change with it.
That matters most when an insurer asked for the tracker in the first place. The proof your insurer sees is tied to the vehicle that was fitted. A tracker sitting in a different vehicle with no updated paperwork does not give them what they asked for. For a fuller picture of that paperwork, read the guide on Thatcham S5 installation certificates and insurers.
Fleet managers meet this situation when a van is replaced at the end of a lease, a car is written off or a vehicle is sold on. The tracker is a physical asset, so it is natural to ask whether it can follow the driver. The short answer is yes in principle, with the right process.
Can I move a Thatcham tracker to a new vehicle?
Yes, in most cases, but only through a professional removal and refit. Do not pull the unit yourself and fit it in the new vehicle. Three reasons apply.
- Thatcham Security Certification is a verification programme for the assessment and recognition of automotive security products, and it concentrates on verifying the functionality, design and performance of the product itself. Crystal Ball’s trackers are sold with nationwide professional installation, so have the refit done professionally too, not at home.
- Your insurer needs to know the vehicle has changed. An unexplained change can leave you without the cover you thought you had.
- Monitoring is tied to the vehicle and account details. If those are not updated, alerts and recovery support may relate to the wrong vehicle.
If you are wondering whether a self-fit is ever sensible, the answer is covered in can I fit a Thatcham tracker myself.
Crystal Ball's S7, S5 and S5 Plus trackers are sold with nationwide professional installation at no additional cost on the original purchase. The current product pages do not set out a transfer arrangement, so do not assume that a move is covered by the same terms. Ask before you book the work and get the answer in writing.
Step by step: how to move a Thatcham tracker to a new vehicle
Use this sequence for any Thatcham category. Each step protects your cover and your monitoring.
- Contact your installer first. Ask whether a transfer is possible for your tracker and what it involves. Ask about any charge before you agree to the work.
- Tell your insurer. Give them the details of the new vehicle and ask what proof of installation they require. Do this before the old vehicle is sold or scrapped.
- Book a professional removal. The installer takes the tracker out of the old vehicle safely, so the vehicle's electrics are left in good order.
- Book the refit and test. The installer fits the tracker to the new vehicle and tests it there.
- Update the monitoring account. The vehicle details on the account must match the new vehicle. Required monitoring is separate from the tracker, so check it as its own item.
- Collect the new paperwork. Keep the installation certificate for the new vehicle with your fleet records and send a copy to your insurer.
- Check the app and alerts. Confirm the live location, journey history and alerts relate to the new vehicle before you rely on them.
The time the work takes depends on the vehicle and the installer. For a guide to what a fitting visit involves, see how long it takes to fit a Thatcham-approved tracker.
What changes for each tracker category
The three Crystal Ball categories do different jobs. That changes what you check after a move.
| Tracker | What it adds | Check after a move |
|---|---|---|
| S7 | Monitored security, real-time location, journey history, tow and tamper alerts | Monitoring and alerts relate to the new vehicle |
| S5 | Everything in S7, plus fob-based Automatic Driver Recognition (ADR) and unauthorised-use alerts | Fob is recognised on the new vehicle and ignition alerts work |
| S5 Plus | Everything in S5, plus immobilisation when the authorised fob is absent | Fob and immobilisation both tested on the new vehicle |
Only refit the category your insurer asked for. If they required S5, an S7 does not meet the request, however good the unit is.
Thatcham S7 tracker: moving a monitored tracker without ADR
The S7 has no fob, no ADR and no immobilisation. That makes a move simpler in one respect: there is no driver fob to pair on the new vehicle.
The checks that remain are the important ones. Confirm the monitoring centre has the new vehicle's details. Confirm the app shows the new vehicle's location and journey history. Confirm tow and tamper alerts reach the right contacts.
Best for: a fleet that needs monitored theft protection and is replacing one vehicle with another of a similar type. For vans, the Thatcham S7 tracker for vans guide explains where this category fits.
Thatcham S5 tracker: moving a fob-based tracker
The S5 includes the S7 functions and adds fob-based ADR. After a move, test that the authorised fob is recognised in the new vehicle. Test the alert that fires at ignition when the fob is not detected.
The S5 does not immobilise the vehicle. Do not tell drivers that the vehicle cannot be started without the fob, because that is an S5 Plus function.
Best for: a fleet that needs monitored security and Automatic Driver Recognition (ADR), where the insurer has asked for S5 specifically. If that is your situation, what to fit when an insurer asks for a Thatcham S5 tracker sets out the decision.
Thatcham S5 Plus tracker: moving an immobilising tracker
The S5 Plus includes the S5 functions and adds immobilisation when the authorised fob is absent. This is the category where a careless move does most damage. An immobiliser that is not tested on the new vehicle gives a false sense of security.
Ask the installer to demonstrate both the fob recognition and the immobilisation on the new vehicle. Make sure drivers know how the fob works on the new vehicle before it goes back into service.
Best for: a fleet that needs ADR plus immobilisation and wants it confirmed after every vehicle change.
Why the cost and effort of moving a tracker varies
No single figure covers every move. Treat any quote you receive as specific to your vehicles. These factors drive the difference.
- The tracker category. S5 and S5 Plus involve a fob, and S5 Plus involves immobilisation, so there is more to test than on an S7.
- The type of new vehicle. A different make or body type changes where and how the unit can be fitted.
- The installer's terms. Whether a transfer is included, charged or declined is set by the installer, so ask.
- Monitoring terms. Required monitoring is priced separately from the tracker. Check whether the plan follows the tracker or needs setting up again.
- Timing. Booking the work before the old vehicle leaves your fleet avoids a gap with no protection.
- Insurer requirements. Some insurers want a fresh certificate for the new vehicle before they confirm cover.
Pros and cons of moving a tracker rather than buying a new one
Pros
- You keep using hardware you have already paid for.
- The driver and fleet manager keep a familiar app and workflow.
- You avoid duplicate equipment if the old vehicle is being retired.
Cons
- The refit takes installer time and may carry a charge, depending on the installer.
- The old vehicle has no protection once the tracker leaves it.
- If the tracker is older, a new unit may suit the replacement vehicle better. Ask the installer for an honest view.
The verdict: moving a tracker suits a straight vehicle-for-vehicle replacement with a reputable installer and an informed insurer. If the old vehicle will stay in service, fit a new tracker to the new one instead.
Can I keep my Thatcham tracker monitoring when I change vehicle?
Monitoring is separate from the tracker and is required for a Thatcham-approved tracker to do its job. Keeping the plan when you change vehicle is a question for your provider. Ask whether the plan follows the tracker and whether the account details can be updated to the new vehicle. If you are weighing the subscription itself, read can you buy a Thatcham tracker without a subscription.
Do I need to tell my insurer when I move a tracker?
Yes. Tell your insurer before the old vehicle leaves your fleet. Insurers that request a Thatcham tracker want proof for the vehicle they are covering, so give them the new vehicle's details and the new installation certificate.
Do not assume cover carries across automatically. Get written confirmation. Never promise a driver that a move changes the premium, because that depends on your insurer.
Can I move a tracker between two vehicles I own at the same time?
Only if you accept that one vehicle is unprotected. A single tracker protects one vehicle at a time. If both vehicles stay in service and both need cover, fit a tracker to each.
FAQ
Can I move a Thatcham tracker to a new vehicle?
Usually yes, through a professional removal and refit with the insurer told and the monitoring account updated. Do not attempt a self-fit swap: Crystal Ball’s trackers are sold with professional installation, so use a professional installer for the refit too.
Is moving a Thatcham tracker free?
Do not assume it is. Crystal Ball’s S7, S5 and S5 Plus headline prices cover the original installation, but the current product pages do not set out a transfer arrangement. Ask your installer for the terms before booking.
Do I need a new installation certificate for the new vehicle?
Ask for one. Your insurer is covering the new vehicle, so the proof of installation should relate to it. Keep a copy with your fleet records.
What happens to my monitoring if I change vehicle?
Required monitoring is separate from the tracker and tied to the vehicle details on the account. Ask your provider to update the account so alerts relate to the new vehicle.
Do I need to retest an S5 Plus after moving it?
Yes. Test that the authorised fob is recognised and that immobilisation works when the fob is absent, on the new vehicle, before it returns to service.
Can I fit a moved tracker myself?
No. A professional refit keeps the installation consistent with the tracker’s Thatcham category and gives you paperwork your insurer can accept.
Should I move the tracker or buy a new one?
Move it for a like-for-like replacement where the old vehicle is leaving your fleet. Buy a new one if the old vehicle stays in service or the installer advises the unit no longer suits the new vehicle.
One last thing
Book the removal before the old vehicle is collected, not after. Once the vehicle has gone, getting the tracker out becomes a recovery job rather than a routine appointment. A fleet manager who tells the installer and the insurer on the same day keeps the new vehicle covered from the first journey.
Before you book a transfer, contact the Crystal Ball team to confirm what a move involves for your tracker, your paperwork and your monitoring account.
