What do we want the public to know?
Keyless car systems are convenient, but they can be targeted by thieves if simple precautions aren’t taken.
Most modern vehicles use key fobs that communicate with the car using radio frequency (RF) signals. These signals allow doors to unlock and engines to start without inserting a key.
How keyless entry works:
Your key fob sends a coded radio signal to the vehicle
The vehicle checks the code matches its system
If recognised, the doors unlock or the engine starts
Many newer cars use “rolling codes”, changing the signal each time for added security
Some vehicles unlock automatically when the fob is nearby – meaning the key doesn’t need to be touched
The risk:
Criminals can use equipment to relay or amplify the signal from a key fob inside a home, allowing them to unlock and steal a vehicle without forcing entry.
How do we want the public to feel?
Reassured that this crime can be prevented
Confident that small steps make a big difference

This advice forms part of our ongoing work to reduce vehicle crime and protect residents as part of national NPCC vehicle crime prevention activity and local neighbourhood priorities.
What do we want the public to do?
Protect your vehicle by taking simple steps:
Store keys in a Faraday pouch at home and when out
Keep spare keys protected too
Avoid leaving keys near doors or windows
Lock your car and check it has locked
A Faraday bag blocks radio signals, preventing criminals from accessing your vehicle electronically. Many police forces issue or recommend these as a proven crime‑prevention measure.
