New Anti-Theft Tech You Probably Didn’t Know Your Car Could Have

As keyless entry becomes more common, so do thefts that exploit it. Gone are the days of smashing windows or hot-wiring engines now, many modern car thefts are silent, fast, and shockingly simple. A criminal with a relay device can intercept the signal from your key fob (even through your front door), unlock the car, and drive off all in under a minute.

But thankfully, car security is evolving too. In this post, we’ll look at three of the most effective, under-the-radar technologies now protecting vehicles from keyless theft many of which most drivers have never even heard of.

Time-of-Flight: The Future of Keyless Entry Security

Time-of-Flight (ToF) is a technology that measures how long a signal takes to travel from your key fob to your car. Unlike standard keyless systems, which just detect signal presence, ToF actually checks whether your key is physically close enough.

That means if a criminal tries to relay the signal using a range extender, the car knows something’s wrong the timing doesn’t add up and access is denied.

Who’s using it?

• Jaguar and Land Rover began rolling out ToF tech on several models from 2022 onward
• Mercedes and BMW are developing similar systems for newer EVs and luxury lines

Why it works:

It runs automatically no action needed from the driver

• It’s invisible to would-be thieves
• It blocks even high-end relay attacks

The catch? It’s currently only available on newer, higher-end models but expect it to become more common soon.

Ghost Immobiliser II: The Secret Engine Lock No Thief Can See

The Ghost Immobiliser II is one of the most effective aftermarket anti-theft systems available in the UK right now. Unlike alarms or trackers, this system blocks the engine from starting unless the driver inputs a unique PIN code using the car’s existing buttons.

No fobs. No tags. Nothing to scan or clone.

Your PIN might be something like: press the window switch, tap the brake, then turn on the heater.
Without the correct sequence, the car stays silent.

Key benefits:

• Undetectable to thieves even with full access to the vehicle
• No additional keys or remotes to carry
• Compatible with most makes and models
• Fully insurance-approved in the UK

For many premium cars especially Range Rovers, BMW X5s, and AMG models Ghost has become the go-to protection against advanced key cloning and signal attacks.

Signal Kill Switches: Simple but Genius

Here’s something most people don’t know: some key fobs have a physical switch inside that cuts off the signal completely.

No signal nothing for thieves to amplify.

How it works:

Some manufacturers, like Toyota, Lexus and Mazda, allow you to deactivate your key by pressing certain buttons or flipping a hidden switch inside the casing.
There are also third-party solutions switches professionally installed into your existing fob.

When switched off, your key can sit safely at home, even close to the front door, without broadcasting anything.

Pros:

1. Extremely simple flick the switch at night, done
2. No need for signal-blocking pouches
3. Works with older key fobs that lack more advanced security features

This method doesn’t rely on electronics or software which also means it can’t be hacked.

Which One Should You Use?

Here’s a quick breakdown:

Security Method What It Does Effectiveness:

1. Time-of-Flight: blocks relay attacks by checking signal distance (built-in to some new models)
2. Ghost Immobiliser II: prevents engine start without a secret PIN (aftermarket install)
3. Key Fob Kill Switch: cuts off the signal entirely (manual use)

The best option? Combine them.
