I've watched car security evolve for nearly four decades.
The hard truth of 2026 is this: the methods that take cars today have almost nothing to do with forcing a lock or smashing a window. They're quiet, quick and electronic — and the cars most at risk are the desirable ones sitting on driveways every night.
This guide explains, plainly, how cars get stolen now, what stops it, and what your insurer is likely to require. No scaremongering — just what I'd tell you if you rang me.
Three methods account for almost all of it.
- 01
Relay attacks
Two thieves work together — one stands near your house with a device that picks up the faint signal from the fob in your hallway and relays it to a second device at the car. The car believes the key is present, unlocks and starts. Your keys never move, and it can be over in under a minute.
- 02
Key cloning / OBD attacks
Once inside, a thief plugs a handheld device into the car's diagnostic (OBD) port — the same port a garage uses — and programmes a blank key in seconds, then drives away.

The common thread
All of these defeat the key. So the real question becomes: how do you protect a car when the key itself can't be trusted?
You stop it by adding protection that doesn't rely on the key — in layers.
1. An immobiliser that needs you, not a key — the Autowatch Ghost. Wired invisibly into the car's electronics, it demands a unique button sequence before the engine will start. Clone the key or relay the fob — without your sequence, the car doesn't move. For most owners, this is the single most effective step.
2. An insurance-approved tracker for recovery — S5 or S7. If a determined thief still gets a car moving, a tracker is how you get it back. An S7 locates the car after you report it stolen; an S5 adds driver-recognition tags and earlier alerts, and is the standard most insurers now want for prestige vehicles.
3. Sensible habits on top. A Faraday pouch and an OBD port lock both help — but they depend on you doing them every single time. That's why a permanent, fitted defence is the foundation.
This is the part catching owners out in 2026.
For high-value and high-risk vehicles — Range Rovers especially — many insurers now insist on an insurance-approved tracker, fitted by an approved installer, as a condition of cover. Some have stopped offering cover at all in certain areas without it.
Crucially, the device usually has to be installed and certified by an approved, accredited fitter for the policy to stand. A device fitted to a price by an unaccredited installer can leave you with a worthless certificate and a rejected claim.
