How Do I Protect My Car From Keyless Theft?

How keyless cars get stolen

Keyless entry lets you open and start the car while the key stays in your pocket. The car simply checks that the key is nearby. Thieves use that against you with a relay attack: one person holds a device near your front door to pick up the key signal, and a second device next to the car passes it on. The car thinks the key is right there, unlocks and starts.

The other common method is plugging into the diagnostic port under the dashboard and programming a blank key. Both can take a minute or two, often in the middle of the night, with no broken glass.

Free and cheap things that help

Keep your keys away from the front door and windows, ideally in a signal-blocking pouch or tin. Test the pouch by walking up to the car with the key inside it. If the car still unlocks, the pouch is not doing its job.

Check your handbook or dealer app, as some cars let you switch off keyless entry or put the key to sleep when it is not moving. A visible steering wheel lock also puts many thieves off, because it slows them down.

What a ghost immobiliser does

A ghost immobiliser stops the engine from starting until you enter a PIN code, using buttons that are already in the car such as the steering wheel or window controls. Even with a cloned or newly programmed key, the car will not drive away without the code.

Because it uses the car's own wiring and buttons, there is no obvious extra box or key fob for a thief to find. You can also set a service mode so the garage or a valet can move the car without knowing your code.

Is it worth fitting one?

If you drive a car that is popular with thieves, park on the street, or have already had an attempt made on the car, an immobiliser is a sensible layer of protection. A tracker is a good partner to it, as it helps get the car back if the worst happens.

It will not stop a car being damaged or towed away, so it works best alongside the simple habits above.
