Buying a Car Tracker in 2026 — What You Need to Know
GPS trackers, 4G telematics, and immobilisers: which is right for your car or fleet?
On this page
In 2026, car trackers are more affordable and capable than ever. But with OBD plug-ins, hardwired GPS units, 4G telematics, and integrated immobilisers on the market, choosing the right solution can be confusing. This guide explains the key differences, subscription costs, recovery rates, and why combining tracking with an immobiliser offers the best protection for UK drivers.
GPS tracker vs immobiliser — what’s the difference?
A GPS tracker tells you where your car is after it’s stolen. An immobiliser prevents the car from being started in the first place. Many drivers buy a tracker thinking it will protect their car, but trackers alone do not prevent theft — they only aid recovery. According to UK police data, vehicles with active trackers are recovered in around 85-90% of cases, but recovery can take days, and vehicles are often damaged or stripped for parts. An immobiliser, by contrast, stops the thief from driving away — preventing the theft entirely. The best solution combines both: a 4G-enabled immobiliser with GPS tracking, like LockCar One Plus.
An AirTag or Bluetooth tracker is NOT a car security device. Bluetooth range is limited to ~30 metres, and thieves can detect AirTags with Android scanner apps. For real security, you need a hardwired GPS tracker with cellular backup — or better, an immobiliser.
Subscription vs no-fee trackers
Many GPS trackers require a monthly or annual subscription for cellular data. Typical costs range from £5–£15 per month. No-fee trackers usually rely on Bluetooth (limited range) or store data locally (no real-time alerts). For real-time tracking and remote immobilisation, a 4G subscription is essential. LockCar One Plus includes a competitive subscription for 4G connectivity, live camera viewing, and remote engine cut — all controlled from your phone.

Why tracking alone isn’t enough
Consider this: a thief steals your keyless-entry car in under 60 seconds using a relay amplifier. You receive a tracker alert on your phone 10 minutes later. By the time you contact police, the car is already in a container or being stripped for parts. An immobiliser prevents this scenario entirely. LockCar’s relay-based immobilisers cut a critical circuit (starter, fuel pump, or ignition) until an authorised tag, phone, or Wi-Fi signal is present. A relay amplifier cannot replicate this signal — the thief simply cannot start the engine.
Can I add a tracker to my existing immobiliser?
Yes. LockCar One Plus includes both functions in one unit. Alternatively, you can add a standalone GPS tracker alongside any LockCar immobiliser.
What’s the monthly cost for 4G tracking?
LockCar offers competitive 4G data plans for One Plus and Duo models. Contact us for current pricing — discounts available for annual prepayment and multi-vehicle fleets.
Will a tracker drain my car battery?
Quality trackers have low-power modes and voltage protection. LockCar systems monitor battery voltage and will shut down safely if charge drops below a preset level.
