Keyless relay theft uses technology to make a vehicle believe its authorised key is nearby. Police recommend combining key management with physical security.
Keyless Car Relay Theft Prevention and VIN Security Records: essential checks
Keep both keys away from doors and windows in a tested signal-blocking pouch and confirm the vehicle is locked manually. A supplementary VIN label does not interrupt a wireless relay attack.
Keep original manufacturer vehicle identification and any security accessories separate in your records. A printed VIN information label does not stop theft, unlock or immobilise a car, and must never be used to conceal an identity mismatch. Apply the police's recommended practical precautions and ask the vehicle manufacturer about model-specific equipment or approved installation.
Practical owner checklist
- Confirm the genuine registration/VIN and retain a secure, accurate record of the vehicle.
- Assess the actual theft risk: keys, parking, removable tools, electronic access, or fraudulent identity.
- Choose appropriate independently tested physical or electronic security rather than relying on decorative stickers.
- Record serialised security equipment and document any legitimate damaged auxiliary identification labels.
UK VIN GROUP: vehicle identification and workshop labels
We provide evidence-reviewed enquiries for independent, unbranded auxiliary VIN or asset labels. We do not issue security certificates, official manufacturer plates, forensic database memberships or a new vehicle identity. Enter a UK registration if available, or the original chassis/VIN for a genuine import without registration. All requests require an appropriate vehicle identity.

Frequently asked questions
Is any metal-lined bag a proven Faraday pouch?
Not necessarily. Choose an appropriately tested product and check that it still blocks the signal periodically.
Can an independent VIN sticker block keyless theft?
No. It may aid identification, not wireless signal security.
Should I reprogramme keys after buying a used car?
Police.uk suggests reprogramming keys when purchasing second-hand where appropriate.
