A new tracker and immobiliser designed to combat vehicle relay theft has been introduced by telematics company Teletrac Navman.

Relay theft sees criminals using transmitters to hijack the signal from a car key fob and use it to unlock their target vehicle.

Teletrac Navman says its Trackstar S5 iPro with Immobilisation product works by incorporating a secondary relay signal connected to a driver ID tag, that is needed for the car to start, meaning thieves won’t be able to drive away even if they gain entry.

The immobiliser is Thatcham approved and therefore compliant with all insurers.

Teletrac Navman connected services managing director Jon Eaves said: “Relay theft has been growing and the technology thieves are using has become more sophisticated and readily available. 

“Immobilisers of this kind aren’t commonplace as either factory fitted or aftermarket installations, so we’re pleased to be filling that void with an additional layer of protection and provide peace of mind that high value assets remain where they’re left.”
