If your car has a button start and a fob that lives in your pocket, you own a keyless car — and the data isn't kind. UK keyless vehicles are stolen at roughly twice the rate of cars with mechanical ignitions. The good news: most of the attacks are well-understood by now, and most of them have cheap, effective defences.
How keyless cars are actually being stolen
Three attack vectors account for the overwhelming majority of UK keyless thefts in 2026:
Relay attack (around 60% of keyless theft)
Two thieves work as a pair. One stands by your front door with a signal amplifier; the other stands by the car with a receiver. The amplifier picks up the weak signal from your key fob — sitting on a hallway table — and relays it to the car. The car thinks the key is present and unlocks. They start it and drive away. Total time: under 90 seconds.
CAN-bus injection (around 20%)
Newer attack — thieves access the vehicle's internal wiring through an entry point like the headlight housing, plug in a small device, and tell the car's computer to authorise a start sequence without any key being present. No signal amplifier needed. Works on many post-2018 vehicles, including a number of premium German brands that have been repeatedly targeted.
Tow theft (around 10%)
The least sophisticated and hardest to fully prevent. A flatbed pulls up, two operatives lift the car onto it, and it's gone. No keys, no signal, no electronics — just brute force. Common for high-value vehicles that the thieves can't replicate keys for.
The seven defences, in order
1. Faraday key pouch (~£15)
The cheapest, most effective single intervention. A Faraday pouch is a small sleeve lined with conductive material that blocks the signal between your fob and the outside world. Drop your keys in it when you get home. No signal, no relay attack. Buys you a complete defence against the most common attack vector for less than the price of a takeaway.
2. Disable the fob signal at night (most makes, free)
Many modern keys can be put into a "sleep mode" by double-tapping the lock button, or by holding the unlock button for a few seconds. Check your owner's manual — your specific car probably has this feature built in. Costs nothing.
3. Steering wheel lock (~£90)
A Disklok or similar full-coverage steering wheel lock looks heavy-handed but works. Thieves are looking for the easier target on the street; visible physical deterrents push them past your car. The cost-effectiveness is in the deterrence, not the lock itself — thieves see the wheel lock and walk away before they've even tried to enter.
4. Driveway bollard or wheel clamp (~£150–£400)
If your car lives on a drive, a manual or hydraulic bollard at the end of it makes drive-off theft physically impossible. Wheel clamps are cheaper but a hassle to use daily. Both work on the same principle as the steering wheel lock: visible friction.
5. OBD port lock (~£25)
If your car is at risk of CAN-bus injection, an OBD port lock physically blocks access to the diagnostic port that's often the entry point for the attack. Doesn't cover headlight-based attacks but covers a meaningful fraction.
6. Active GPS tracking with 24/7 monitoring (£300–£500/year)
The defence of last resort — for the moment prevention fails. A monitored tracker means that when (not if) someone defeats all of the above, you have a 24/7 UK monitoring centre and a recovery network to actually get the vehicle back. This is what AAsset Protect does.
7. Park sensibly
The boring one. Most UK theft happens overnight from residential streets and driveways — not from public car parks. If you have a garage, use it. If you have a drive, don't leave the car furthest from the house. If you only have street parking, park under a street light where possible.
What about insurance?
Comprehensive insurance covers theft. But "covered" means a claim — not your car back. Most insurers will pay out the market value of your stolen vehicle, minus your excess, after some weeks of investigation. You'll be without your car for the whole period. You'll likely face a premium increase on renewal. And if you've modified the vehicle, fitted aftermarket parts, or have it in storage outside specified hours, the claim might be challenged.
The optimal UK setup for 2026 is layered: prevention (1-5) + active recovery (6) + insurance as the worst-case backstop. Skipping any layer leaves a gap.
The bottom line
Keyless theft isn't mysterious. The attack methods are well-understood, the defences are cheap, and the data showing what works is publicly available. For under £100 most UK drivers can defend against the most common attacks. For the more determined thieves — and the ones increasingly working as organised crime — active monitoring and recovery is the final layer that matters.
