Best Car Trackers with Immobiliser: Reviewed and Ranked By Our Experts

Below is a closer look at how each of these systems performs on theft prevention, recovery capability and overall value, ranked according to genuine comparison.

1. GPSBob Thatcham S5 Plus

The GPSBob Thatcham S5 Plus takes the top spot because it directly addresses the theft methods that trackers alone can't stop, using Automatic Driver Recognition and TOTP technology tags to enforce a strict "No Tag, No Start" policy. Rather than only alerting you once a vehicle has already been moved, it works to prevent unauthorised starting in the first place, making it a genuinely proactive rather than purely reactive solution.

Compared with the Meta Trak S5 Deadlock, Scorpion S5+ and Autowatch Ghost 2, the S5 Plus offers a compelling combination of insurer-recognised Thatcham S5 compliance under TSC597 and an affordable, flexible subscription structure with no long-term commitment required. It also comes with free nationwide installation and 24/7 monitoring as standard, giving it an edge over rivals that charge separately for fitting or lock buyers into fixed annual plans.

Rating: 4.9/5, reflecting consistently strong Trustpilot and Google reviews.

Pricing: £449.00 for the device, plus a choice of subscription plans:

• £9.99 pay monthly, cancel anytime, no commitment

• £116.28 prepay for 1 year, saving up to 3%

• £225.37 prepay for 2 years, saving up to 6%

• £327.27 prepay for 3 years, saving up to 9%

• £421.98 prepay for 4 years, saving up to 12%

• £509.49 prepay for 5 years, saving up to 15%

Key features:

• Automatic Driver Recognition (ADR) with immobilisation

• TOTP technology tags for secure driver identification

• "No Tag, No Start" enforcement against relay and cloning attacks

• 4G-enabled real-time GPS tracking with instant unauthorised movement alerts

• 24/7 monitored control room and free nationwide installation

2. Meta Trak S5 Deadlock w/ Driver Immobilisation

The Meta Trak S5 Deadlock earns a strong second place by combining Thatcham Category S5 tracking with driver-controlled immobilisation that arms automatically the moment the engine is switched off. Its "No Tag, No Start" system means no unauthorised person can start the vehicle regardless of the technique attempted, and the Deadlock feature can also be triggered remotely through the Meta Trak app if keys are ever stolen.

Against the GPSBob S5 Plus, the Deadlock offers similar driver recognition credentials but at a slightly higher device price and with a fixed annual subscription rather than a flexible monthly rolling option. Compared with the Scorpion S5+ and Autowatch Ghost 2, it sits in the middle on price while still delivering comprehensive protection against key theft, cloning and relay attacks.

Rating: 4.7/5, reflecting solid insurer recognition and robust immobilisation control.

Pricing: £479.00 for the device, plus a choice of subscription plans:

• £149.95 annual subscription

• £399.95 for 3 year subscription

Key features:

• Driver controlled immobilisation, arming automatically on ignition off

• Remote immobilisation via the Meta Trak mobile app

• DRS driver ID tags with instant tow-away alerts

• 24/7 European control room monitoring

• 3 year warranty and full transferability to a new vehicle

3. Scorpion S5+ with Immobilisation

The ScorpionTrack S5+ stands out for its Automatic Driver Recognition, designed and manufactured in the UK to Police Preferred Specification, making it a favourite for owners of high value and desirable vehicles. It responds to the full range of modern theft techniques, including key theft, key cloning, OBD hacking and relay theft, all backed by 24-hour control room monitoring and European coverage.

Compared with the GPSBob S5 Plus and Meta Trak S5 Deadlock, the Scorpion S5+ offers similar "no tag, no start" functionality but with a wider price range depending on vehicle type and fitting complexity, stretching from £599.00 up to £1,218.00 including VAT and fitting. It's a premium choice that justifies its cost through Police Preferred Specification and a 3 year device warranty, but it's a bigger investment than the S5 Plus or Deadlock for drivers who don't need that level of specification.

Rating: 4.7/5, based on strong recovery credentials and driver recognition performance.

Pricing: £599.00 to £1,218.00 including VAT and fitting, plus a choice of subscription plans:

• £189.00 for 1 year

• £289.00 for 2 years

• £379.00 for 3 years

• £459.00 for 4 years

• £529.00 for 5 years

• £619.00 for a lifetime subscription

Key features:

• Automatic Driver Recognition (ADR) with "no tag, no start" technology

• Remote immobilisation as standard

• Multi-vehicle tracking with GPS, GLONASS, Galileo and GSM

• Battery backup with low battery and tow away alerts

• 3 year device warranty, transferable to a new vehicle

4. Autowatch Ghost 2 Immobiliser & Track Manager S5

The Autowatch Ghost 2 paired with the Track Manager S5 offers genuine dual-layer protection, combining a customisable PIN-based immobiliser using the car's existing buttons with a fully Thatcham-approved S5 tracker. If a thief somehow gets past one layer, the other is designed to stop them, which makes this bundle particularly appealing for high-risk vehicles.

Against the GPSBob S5 Plus, the Ghost 2 works on a similar principle of blocking unauthorised starts, but this package adds the recovery benefit of a dedicated S5 tracker with driver ID tag authentication bundled directly into the price rather than as a separate line item. Priced at £649.00, it sits above the S5 Plus but offers a genuinely comprehensive package for owners who want both prevention and recovery bundled together at a reasonably competitive rate.

Rating: 4.6/5, reflecting strong dual-layer protection and insurer recognition.

Pricing: £649.00 for the package, plus a choice of subscription plans:

• £130.00 for 1 year

• £249.00 for 2 years

• £326.00 for 3 years

• £13.99 monthly direct debit

Key features:

• Customisable PIN code using the vehicle's own steering wheel or console buttons

• Undetectable installation with no radio signals, fobs or LED indicators

• Driver ID tag authentication with instant security alerts

• 24/7 professional tracking with theft recovery support

• Service and valet mode for temporary deactivation during servicing

How to Choose the Best Car Tracker with Immobiliser

• Decide whether you need prevention, recovery or both. Immobilisers stop unauthorised starts, while trackers help recover a stolen vehicle, so a combined system covers both bases.

• Check your insurer's exact requirement. Some policies specify Thatcham S5 for high-value vehicles, so confirm which category applies before buying.

• Consider relay attack and cloning resistance. Systems using hidden PIN sequences or driver ID tags are more effective against these increasingly common theft methods than basic alarms.

• Weigh upfront cost against subscription fees. Some devices are a one-off payment, while others require ongoing monitoring fees that add up over several years.

• Look for warranty and transferability. Longer warranties and the ability to move the system to a new vehicle add long-term value.

• Confirm installation doesn't affect your warranty. Reputable systems use the vehicle's original wiring and CAN-BUS system without cutting or modification.

• Read genuine customer reviews. Ratings above 4.5/5 on Trustpilot or Google generally indicate reliable installation and support.

FAQs

Can a car tracker with immobiliser be bypassed by thieves?

It's designed specifically to resist this, as it doesn't rely on the vehicle's standard key or fob system that relay attacks and cloning target.

Do combined tracker and immobiliser systems cost more to insure?

No, they typically lower premiums rather than raise them, since insurers view dual-layer protection favourably for high-risk vehicles.

How long does installation of a tracker with immobiliser take?

Most professional installations are completed within a few hours, though mobile fitting appointments are often booked within 1 to 3 working days.

Can I still start my car normally after fitting an immobiliser?

Yes, once the correct sequence, PIN or driver tag is used, the vehicle starts as normal with no noticeable delay.

Are these systems suitable for vans and motorhomes as well as cars?

Yes, most Thatcham-approved trackers with immobilisation are compatible with cars, vans, motorhomes and other 12/24 volt vehicles.
