CAN injection: when thieves talk to the car's own wiring
Most at risk: Newer cars, often premium SUVs and pickups, with or without keyless entry.
What can injection is
Modern cars use an internal network so the engine, locks and dashboard can exchange messages. In a CAN injection theft, criminals reach part of that network from outside the bodywork and send false messages telling the car a genuine key is present.
Because the fob is never involved, signal-blocking pouches give no protection here. Security researchers have shown that this method lets thieves take cars with no obvious damage beyond a disturbed panel or light.
How owners usually notice: Damage, if any, tends to be small and around the front of the car, such as a loosened trim panel or headlight surround.
Stop can injection with dual layer protection
Layer one: an immobiliser that ignores the fake messages
A separately wired aftermarket immobiliser keeps the engine cut until its own code or tag is given. Messages forged on the car's network cannot supply it, so the vehicle stays put even after the trick works. Read more.
Layer two: a tracker that keeps reporting
Pair it with a professionally fitted tracker, ideally with movement alerts, so you hear about any attempt at once and police get a location if the car is taken. Read more.
Talk to an installer about both layers.
Everyday habits that help
- Park nose-in to a wall or garage door where it is practical, so the front of the car is harder to reach.
- Use a camera or light that covers the front corners of the car at night.
- A physical steering or pedal lock adds a third, visible obstacle.
