In addition to alarms that are now standard in all cars, modern advanced technology has been used.

-It is about "sleeping" car keys, which means that if a key is not moved in two minutes it goes into sleep mode and stops sending signals. Other measures are chassis number-linked navigation systems, which means that the car's navigation equipment only works in the car it is mounted in, says Peter Maier, communications manager at BMW Sweden.

Complex crime

But according to him, car theft is just the tip of an iceberg of far more complex crime.

-There are big international leagues behind, Sweden is like a sandwich table for the thieves. Just go here and steal tractors, car parts, boat engines and horse saddles. We will never overcome the problem unless the customs get more powers. And can control what is brought out of the country.
