Best GPS car tracker with immobiliser: what to look for
LockCAR makes vehicle security in the UK. A tracker finds a stolen car, an immobiliser stops it being stolen, and a system that does both covers the cases each one misses. This guide shows what to check before you buy, and where our own systems fit.
- GPS + immobiliser + dashcam
- From £499 fitted
- One app
Why combine a tracker and an immobiliser
Prevention and recovery are different jobs.
The immobiliser covers
- Relay attacks on keyless cars
- New keys programmed through the diagnostic port
- Anyone trying to drive the car without your TAG, ring, watch or PIN
The GPS tracker covers
- A car lifted onto a truck and towed
- Knowing where the car is at any time
- Alerts the moment the car moves
On its own, a tracker only tells you where the car went, and recovery depends on how fast the police can act. On its own, an immobiliser cannot stop a car being towed. Together they cover both.
What to check before you buy
Six questions that separate a useful system from a gadget.
- 4G connection
- Live location and alerts need a mobile connection. Ask what the data plan costs and what happens when it ends.
- How the immobiliser disarms
- A tag, a phone, a wearable or a PIN. Choose what fits your routine, because a system you switch off is no protection.
- Alerts you will actually see
- Movement, impact and geofence alerts on your phone, with settings you can change.
- Professional fitting
- A hidden, hardwired install with a permanent supply lasts longer and is harder to find than a plug-in unit.
- Insurer requirements
- Some insurers ask for a specific approved tracker on high-value cars. Check your policy first.
- One app, one supplier
- One install and one app are easier to live with than two systems from two companies.

- Owners of high-value carsSupercars, classics and premium SUVs are taken to order, whole or in parts.
- Electric and hybrid driversMany EVs are keyless, and the tracker shows where the car is while it charges.
- New drivers and their parentsLocation and journey history give peace of mind without a phone call.
- Vans and small fleetsOut-of-hours alerts and remote immobilisation protect the vehicle and the tools inside.
GPS tracker or AirTag?
Good for keys, not for a stolen car.
An AirTag is a cheap way to find lost keys, but it is not a vehicle tracker. It reports its position only when an Apple device passes nearby, it has no live alerts when the car moves, and an iPhone carried by a thief will warn them that an unknown AirTag is travelling with them. A hardwired 4G GPS tracker reports on its own, alerts you when the car moves, and is hidden inside the car.
Questions about GPS trackers with an immobiliser
What is the best GPS car tracker with an immobiliser?
The best one is a system you will keep switched on: 4G tracking with alerts, an immobiliser that disarms the way you like, and professional fitting. The LockCAR One Plus 4G does all three for £499 fitted, with a dashcam included.
Does a GPS tracker stop my car being stolen?
No. A tracker helps find the car afterwards. An immobiliser stops it being driven away. A system with both covers theft and towing.
Will a hardwired tracker drain my battery?
A professionally fitted system uses a fused permanent supply and is set up to draw little power when parked. If the car stands for weeks, ask the installer about parking settings.
Can thieves jam a GPS tracker?
Jammers exist, which is why an immobiliser matters: a jammed tracker cannot report, but the engine still does not start without your TAG, ring, watch or PIN. Read more in can trackers be jammed.
Is LockCAR Thatcham approved?
Not yet. Our immobilisers are going through Thatcham Security Certification. If your insurer asks for a specific approved tracker, fit that one.
