🔒 New UK Law Targets Signal Jammers & Relay Theft Devices
The UK government has introduced major new powers targeting the electronic gadgets increasingly used in modern vehicle theft.
Under the new Crime and Policing Act 2026, it is now illegal to:
- Own
- Import
- Supply
- Modify
- Manufacture
electronic devices linked to vehicle theft, including:
- Signal jammers
- Relay devices
- Signal amplifiers
- CAN bus injectors
Anyone caught with these devices could face:
⚠️ Up to 5 years in prison
⚠️ Unlimited fines
The law comes as keyless vehicle theft continues to rise across the UK.
🚨 Why This Matters To UK Drivers & Tradespeople
Modern vehicle theft has evolved.
Criminals are no longer relying solely on forced entry or stolen keys.
Instead, organised gangs increasingly use electronic equipment capable of:
- Capturing wireless key signals
- Blocking locking signals
- Disabling trackers
- Unlocking vehicles silently
- Starting vehicles without physical keys
According to government figures, electronic devices are now linked to a significant percentage of UK vehicle thefts, with the Metropolitan Police estimating they are used in around 60% of vehicle thefts in London.

🔧 What Is A Relay Theft Attack?
STEP 1
One thief stands near your home attempting to detect the wireless key signal.
STEP 2
A second device relays the signal to the vehicle outside.
STEP 3
The vehicle believes the genuine key is nearby.
STEP 4
The van or car unlocks and starts without forced entry.
What Is A Relay Theft Attack?
Relay theft works by extending the signal from your key fob.
Typically:
Step 1
One thief stands near your home attempting to detect the wireless key signal.
Step 2
A second device relays the signal to the vehicle outside.
Step 3
The vehicle believes the genuine key is nearby.
Step 4
The van or car unlocks and starts without forced entry.
Many thefts happen in under 60 seconds.
The Rise of Keyless Theft & Relay Attacks
Modern thieves are no longer smashing windows and forcing locks. Many now use advanced electronic equipment to steal vehicles silently in under a minute.
Relay theft devices can:
- Capture key fob signals from inside homes
- Amplify signals to trick vehicles into unlocking
- Start vehicles without physical keys
- Disable trackers and onboard security systems
Recent reports show these devices are widely available online and are being used heavily by organised gangs.
The UK government has now introduced new legislation making possession of electronic vehicle theft devices illegal, carrying penalties of up to five years in prison.
However, prevention remains critical.
Why The Government Changed The Law
Previously, police often needed to prove the device had already been used in a theft.
The new law allows earlier intervention by criminalising possession itself in many circumstances.
This is designed to disrupt organised vehicle theft networks before crimes occur.
Government reports also highlight the major financial impact vehicle theft creates for:
- Businesses
- Tradespeople
- Fleet operators
- Insurers
- Private vehicle owners
