Once a car alarm or a large lockable “lever” on the steering wheel was enough to protect and secure the car against theft. Today, however, with the increasing electronics in the car and software, it is very easy to bypass any car security. Thieves of modern and expensive cars are usually well equipped for standard security from manufacturers, especially in the case of a keyless start. And so it happens that expensive cars are stolen by amateurs.
If the thieves are real pros, common alarms or even competing products can be bypassed. The basic rule for securing a vehicle against theft is to put pressure on thieves and complicate and prolong the theft of the car as much as possible. The long duration of car theft increases the chance of detecting a thief who can give it up after a long time.
