Keyless Entry car theft protection

Relay attack is a form of keyless car theft. Criminals bypass keyless entry security by extending the signal of the car key from the home. Automobile associations, insurance companies and many other car experts warn of security problems in cars with Keyless Entry systems. Thousands of cars are stolen yearly by relay attack and this type of keyless entry theft is increasing daily.


Wat is relay attack?

  1. Thief 1 stands close to the vehicle and uses an rfid device to extend signals from the vehicle to thief 2.
  2. Thief 2 stands close to the house, often at the front door or window and uses a second rfid device.
  3. The second device sends the extended signal up to 10-15 metres into the house.
  4. When the key inside the house receives the extended signal, it responds to the car as if the key were close to the vehicle. This allows the car to be opened and started.

Car key security: what options are there?

For many brands, the car key signal appears to be easily extended. Even if the key appears to be securely stored. Insurers recommend a number of options to prevent relay attack as much as possible. However, these are not always available, feasible or desirable in practice.

  • Contact the dealer. For some makes and models, there are already smart keys available that are relay attack protected.
  • Have your vehicle’s keyless entry system disabled
  • Store the key at least 6 metres away from your front door, and don’t leave the spare key lying around either
  • Invest in an additional security system
  • Park the car in a safe place, preferably in a garage
  • Store the key in a metal can or a special case
