If you have lost your S5 tracker tag, contact your tracker’s monitoring provider as soon as possible. A tracker tag is essential for confirming that an authorised person is driving. In many vehicles fitted with a standard S5 tracker, you can still drive without the tracker tag, but the system may treat the journey as unauthorised and send an alert to the monitoring centre. If your tracker includes No Tag, No Start immobilisation, the vehicle may not start—or may not restart once the ignition has been switched off.
Do not assume that every S5 system behaves in the same way. Check which tracker is installed, use a spare tag if you have one and speak to the provider before making an unnecessary journey.
Always keep your tracker tag in a designated place to avoid losing it. Each S5 tracker system relies heavily on the functionality of the tracker tag for proper operation.
Understanding the importance of the tracker tag can prevent unnecessary confusion and alerts while you’re driving.

What is an S5 tracker ADR tag?
ADR stands for Automatic Driver Recognition. It is one of the main features that distinguishes an S5 tracker from an S7 tracker.
The authorised driver carries a small electronic tag, card or other approved identification device. When the vehicle is started or moved, the tracker checks whether it can detect a recognised tag. If no valid tag is found, the system can send an alert to the secure monitoring centre for investigation.
This provides an extra layer of protection against theft involving stolen keys, key cloning or relay methods. A thief may have possession of the vehicle’s keys, but they are unlikely to have the separate driver-recognition tag.
Some providers also offer smartphone-based driver recognition, although availability depends on the tracker model and the way the system was configured. SmarTrack, for example, lists both physical driver-detection cards and compatible mobile driver identification on certain S5 systems.
S5 vehicle tracking systems are assessed under the Thatcham Security Certification programme, which evaluates the functionality, design and performance of vehicle-security products.
Can you still drive after losing an S5 tracker tag?
Standard S5 trackers
In many cases, yes, the vehicle can still be driven with a standard S5 tracker when the ADR tag is missing.
The tag does not necessarily control the vehicle’s original ignition or factory immobiliser. Its primary purpose is to confirm that the person moving the vehicle is authorised.
However, driving without it may create an unauthorised-driver alert. The monitoring centre may then contact you using the details registered to the tracking account. Trackstar’s S5 guidance, for example, explains that movement without the correct recognised tag can generate an alert for its control desk. Meta Trak also states that its monitoring centre may contact an owner following a “No ID Tag recognised” alert.
Even when you know the journey is legitimate, the monitoring centre does not automatically know that. Reporting the missing tag before driving can reduce confusion and help the operator deal with any alert correctly.
S5 trackers with No Tag, No Start
The situation can be different when the tracker is linked to an immobilisation feature.
A No Tag, No Start system is designed to prevent the vehicle from starting—or prevent it from restarting—when an authorised tag is not detected. Some systems automatically immobilise the vehicle after the ignition is switched off and require the driver-detection tag to release the immobilisation.
SmarTrack describes this behaviour on its No Tag, No Start products, while Trackstar distinguishes its standard Secure S5 tracker from its S5 iPRO system with No Tag, No Start protection.
This means a vehicle may currently be running normally but could fail to restart after you stop. Before switching off the ignition somewhere inconvenient, contact the provider or installer and confirm how your particular system operates.
What happens when you drive without the ADR tag?
The exact response depends on the tracker brand, model, subscription and installation configuration.
| Type of system | What may happen without the tag | What you should do |
|---|---|---|
| Standard S5 tracker | Vehicle may drive normally, but an unauthorised-driver alert may be generated | Contact the monitoring provider before driving |
| S5 with a spare tag available | Vehicle should recognise the spare if it is active and correctly paired | Use the spare and report the original tag missing |
| S5 with smartphone identification | The approved app may identify you, depending on the system | Check that the app, Bluetooth and permissions are working |
| S5 with No Tag, No Start | Vehicle may not start or may not restart after the ignition is turned off | Do not rely on assumptions; contact the provider |
| Tag lost with the vehicle keys | There may be a greater security risk because both identification devices are missing | Report both immediately and consider reprogramming the vehicle keys |
An alert does not necessarily mean the police will automatically attend. The monitoring centre normally needs to verify what has happened and follow the provider’s theft-confirmation procedure.
Answer calls from the monitoring centre promptly. Make sure the telephone number registered to your tracking account is current and that the provider is not blocked or silenced on your phone.
What should you do immediately?
1. Check whether you have a spare tag
Many S5 systems are supplied with more than one driver-recognition tag, although this should never be assumed without checking your original paperwork.
Look in the place where you keep:
- Spare vehicle keys
- Tracker installation documents
- Subscription information
- Emergency contact details
- Insurance certificates and security documents
The spare should ideally be stored securely and separately from the main set of vehicle keys. Keeping both tags together means both could be lost or stolen at the same time.
2. Identify the tracker provider
You need to know which company monitors the tracker because replacement tags are not normally interchangeable between different systems.
Check:
- The tracker installation certificate
- Your subscription renewal emails
- Direct-debit or card-payment records
- The tracking app installed on your phone
- Stickers or documents supplied after installation
- Emails from Safe & Sound Mobile or the monitoring provider
Do not buy a generic-looking replacement tag online. It may be incompatible, unprogrammed or unsuitable for your tracker.
3. Contact the monitoring centre
Tell the provider:
- That the ADR tag has been lost
- Whether you still have another working tag
- Whether the vehicle needs to be driven
- Whether the tag was lost separately or with the vehicle keys
- Whether you are receiving alerts or calls
- Whether the vehicle has an immobilisation function
The provider can explain whether the vehicle remains driveable and what will happen if the ignition is switched off.
4. Ask for the missing tag to be disabled
Where supported, the missing tag should be removed or blocked from the tracker account. This is particularly important if you believe it was stolen rather than simply misplaced.
Disabling the tag prevents it from continuing to act as an authorised driver identifier if someone later finds it.
The procedure varies between brands. Some providers can update the account remotely, while others may require the remaining tags to be present or the vehicle to be attended by an approved technician.
5. Arrange a replacement
Replacement tags are generally arranged through the monitoring provider, supplying dealer or an approved installer. Meta Trak, for example, directs customers to an approved dealer for additional or replacement driver ID tags.
The new tag must be compatible with the installed tracker and correctly registered or paired to the vehicle. Simply receiving a tag does not necessarily mean it is ready to use.
Be proactive in managing your tracker tag to ensure a safe driving experience.
Safe & Sound Mobile can help identify the installed system and advise whether replacement-tag programming or a professional inspection is required. Nationwide mobile installation is available for compatible vehicle-security products, so assistance can be arranged at a suitable home or workplace location where applicable.
Regular checks on your tracker tag will enhance vehicle security.
Ensure that you understand how to operate your tracker tag correctly.
Without a tracker tag in your possession, driving may become complex.
Always treat your tracker tag with care to prevent misplacement.
Remember, the tracker tag is your key to safe vehicle operation.
Make sure that your tracker tag is stored securely when not in use.
Keep your tracker tag accessible to ensure smooth vehicle operation.
Always have your tracker tag on hand during your journeys.
Address any issues with your tracker tag as they arise.
What identification might be required?
Tracker providers must protect access to vehicle-location and account information. They may therefore ask security questions before discussing the system or issuing a replacement.
Depending on the provider, you may be asked for:
- Your full name and address
- The vehicle registration number
- The tracker account or subscription number
- Details from the installation certificate
- The vehicle identification number
- A password or memorable security answer
- Proof that you are the registered keeper or authorised account holder
- Confirmation of recent payments or subscription details
Requirements differ, so have your tracker paperwork available when you call. Do not send sensitive identification documents to an unverified email address or social-media account.
Why you should not ignore a missing tag
Repeated false security alerts
Driving without a recognised tag can repeatedly generate alerts. This creates unnecessary calls and makes it harder for the monitoring provider to distinguish a legitimate journey from a genuine theft.
Reduced driver-recognition protection
The tracker may still provide location information, but the driver-recognition part of the system is not operating as intended if you have no active tag or alternative identification method.
Possible immobilisation problems
With No Tag, No Start, the vehicle may leave you unable to restart after stopping. This could happen at home, at work, at a petrol station or during a longer journey.
Insurance questions
Some insurers require a functioning S5 tracking system as a condition of cover for certain vehicles. A lost tag does not automatically mean your insurance is invalid, but you should check your policy rather than make assumptions.
If a replacement cannot be arranged promptly, ask the monitoring provider whether the system still meets its normal operating requirements and contact your insurer if necessary.
Security risk when keys are also missing
A tag lost by itself is inconvenient. A tag lost with the vehicle keys is more serious because the person finding them may possess both the means to unlock the vehicle and the device used to identify an authorised driver.
Report the loss immediately and discuss whether the tag, tracker account and vehicle keys need to be reprogrammed.

Frequently asked questions
1. Will my car stop while I am driving without the S5 tag?
A correctly configured vehicle-security system should not unexpectedly stop a moving vehicle simply because a tag is absent. However, a No Tag, No Start system may prevent the engine from restarting after the ignition has been turned off. Confirm the operation of your particular tracker with the provider.
2. Will the monitoring centre call me?
It may. Standard S5 systems can generate an alert when the vehicle moves without a recognised tag. The monitoring centre may call the registered account holder to verify that the vehicle is safe.
3. Can I use my spare tag immediately?
Usually, provided the spare is active, paired with the system and has a working battery. Test it according to the provider’s instructions and still report the original tag as missing.
4. Can any S5 replacement tag be programmed to my tracker?
No. Tags are system-specific and must be compatible with the installed equipment. Obtain the replacement through the tracker provider, an approved dealer or your professional installer.
5. Can my phone replace a lost ADR tag?
Some S5 trackers support approved smartphone driver recognition, but not every product does. The feature may also require the correct app, account setup, Bluetooth connection and phone permissions. Check with your provider before relying on it.
6. Do I need a completely new tracker?
Usually not. A lost tag can often be replaced and registered to the existing tracker. A new system may only be considered if the current tracker is unsupported, inactive, incompatible with your requirements or has another fault.
Need help with a lost S5 tracker tag?
Losing an ADR tag does not usually mean that the complete tracker needs replacing, but it should be dealt with promptly. Safe & Sound Mobile can help you identify your installed system, understand whether the vehicle remains driveable and arrange suitable professional support where available.
Safe & Sound Mobile also supplies professionally installed S5 and S5 Plus tracking systems for cars, vans, motorhomes and other compatible vehicles, with nationwide mobile installation available.
