Car key hacking is now the leading method of vehicle theft in the UK, accounting for 58% of all incidents between April 2023 and March 2024—up from just 13% in 2018–2019, according to RTA Law's analysis of ONS data. This sharp rise reflects the growing sophistication of organised crime and exposes major vulnerabilities in modern vehicle security.
What Is Car Key Hacking?
Known as relay theft, criminals intercept or amplify the wireless signal between a key fob and the vehicle, allowing them to unlock and drive off without the actual key—often in under a minute.
Rod Mitchell of RTA Law said:
"This surge mirrors advances in car tech. As vehicles evolve, so do criminals. We must stay one step ahead."
New Legislation Responds
To combat this, February 2024 legislation now makes it illegal to possess signal jammers, relay devices, or similar tools, even without proof of their use in a crime. Offenders face up to five years in prison—marking a major legal shift.
Top Theft Methods (2023–2024):
• Relay/key signal attacks – 58%
• Key or fob use – 18% (down from 33% in 2018)
• Forced locks – 13%
• Unlocked doors/other – 5% each
• Broken/prised entry – 4% or less
With a vehicle stolen every 8.5 minutes in Britain, this is not just a crime trend—it’s a public safety concern.
How to Protect Your Vehicle:
-
Install an Immobiliser – Disables the engine without the correct signal.
-
Store Keys Wisely – Keep fobs away from windows/doors to block signal boosting.
-
Disable Keyless Entry – Use onboard settings or physical devices like steering locks.
-
Use a Tracker – A Thatcham-approved tracker boosts recovery odds and may deter theft.
Conclusion: Act Now
The surge in digital vehicle thefts demands immediate action. While automakers enhance security features, criminals continue to exploit wireless vulnerabilities. Public awareness, strong enforcement, and personal vigilance are essential to stopping this growing threat.
