Keyless cars made life easier — and, unfortunately, made thieves’ lives easier too. Across the UK, “relay” theft now lets criminals drive away with a modern car in under a minute, without ever touching your keys. For drivers in Norwich, Ipswich, Cambridge and the surrounding towns, it’s worth understanding how this works and, more importantly, how to stop it.
This guide explains keyless theft in plain English, shows which cars are most at risk, and walks through the layers of protection that actually work — from a £10 pouch to a dealer-level Ghost immobiliser.
What Is Keyless (Relay) Theft and How Does It Work?
If your car unlocks as you approach and starts with a button, it’s constantly listening for your key fob’s signal. In a relay attack, two thieves work together: one stands near your house with a device that picks up your fob’s signal through the wall, and “relays” it to a second device held by an accomplice at your car. The car is fooled into thinking the genuine key is present — so it unlocks and starts. No broken glass, no forced locks, often under 30 seconds.
Which Cars Are Most at Risk?
Any vehicle with keyless entry and push-button start is a potential target — and that now includes a huge range of everyday cars, vans, SUVs and motorbikes, not just high-end models. Newer, in-demand vehicles are especially attractive because there’s a ready market for stolen parts and exports. If you have to physically press a button on the fob to unlock, you’re at lower risk — but layered protection is still wise.
6 Ways to Protect Your Car (Think in Layers)
No single gadget is a silver bullet. The best protection stacks simple deterrents on top of serious electronic security, so a thief gives up and moves on.
- Faraday pouch. A cheap signal-blocking pouch for your fob stops relay attacks at the source. Keep keys away from the front door, too.
- Visible physical deterrent. A steering wheel lock or wheel clamp won’t stop a determined gang, but it slows them down and makes your car the less appealing option.
- Ghost immobiliser. The strongest layer — an electronic immobiliser that needs a secret PIN sequence to drive, with no signal for thieves to copy. More on this below.
- Vehicle tracker. If the worst happens, a tracker dramatically improves the odds of fast recovery — and can lower insurance premiums.
- OBD port protection. Some thieves plug into the diagnostic port to programme a blank key. A lockable cover blocks this route.
- Park smart. Use a garage or well-lit, overlooked spots, and angle cars so a driveway vehicle blocks the one behind it.
Why a Ghost Immobiliser Is the Gold Standard
The Autowatch Ghost II is the protection we most often recommend, because it defeats relay theft, key cloning and even key theft. It connects to your car’s existing buttons — on the steering wheel, doors or centre console — and you set a personal PIN sequence (like a code entered through the buttons). Without that sequence, the engine simply won’t start, even with the genuine key.
- Undetectable: it emits no radio signal, so thieves’ scanners can’t find it.
- No extra fobs: nothing for a relay device to copy.
- Keyless-theft proof: relaying your fob is useless without the PIN.
- Service mode: a temporary code lets a garage or valet move the car without your PIN.
It’s a discreet, powerful upgrade we install across the region as part of our locksmith and vehicle security services.
Vehicle Trackers: Recovery and Insurance Benefits
A tracker is your safety net. Pairing one with a Ghost immobiliser means that in the rare event a vehicle is taken, you can locate it quickly and give police a live position. Trackers also bring everyday benefits:
- Many insurers require or reward tracking on higher-value vehicles, which can reduce premiums.
- Fleet and business owners gain route efficiency and driver oversight.
- Real-time peace of mind — check on your car, van, motorbike or HGV any time.

Already Replacing or Worried About Your Keys?
Security and keys go hand in hand. If you’ve lost a key, getting the old one deleted from the car is itself an anti-theft step — our guide on what to do when you’ve lost your car keys with no spare explains the process. And if a key is worn or damaged, sorting it before it fails avoids an emergency later.

Frequently Asked Questions
How does keyless car theft work?
Thieves use two relay devices to capture and extend your key fob’s signal from inside your home to your car on the drive. The car thinks the genuine key is nearby, so it unlocks and starts — often in under 30 seconds, with no damage.
Does a Ghost immobiliser stop keyless theft?
Yes. A Ghost immobiliser requires a secret PIN sequence entered through the car’s buttons before the engine will start. Because it emits no signal and uses no extra fob, relaying your key is useless — the car won’t move without the PIN.
Will a Faraday pouch protect my car?
A Faraday pouch blocks your fob’s signal, which stops the most common relay attack — a great cheap first step. For full protection, combine it with an immobiliser and tracker.
Can a tracker lower my insurance?
Often, yes. Many insurers reduce premiums for vehicles fitted with an approved tracker, and some require one for higher-value cars. A tracker also greatly improves recovery chances after a theft.
