Your car also changes the price of each. - **Alarm:** Warns you when someone touches the car, and with an engine block it stops the engine from starting. The price changes with what the alarm does: only sounds, alerts your phone, or also shows where the car is. The engine block, extra sensors and the work on your car change it too.

The price changes with which device suits your car and how you unlock it: with a fob, a code or your phone.

The price changes with the device, hidden fitting and whether you track the car outside Serbia. [More about GPS tracking](https://autoindustrija.rs/en/services/gps-vehicle-tracking) - **OBD port protection:** The OBD port is where diagnostics are plugged in. Through it a thief makes a new key in a few minutes. Relocating or blocking the port closes that way in. The price depends on which one you choose.

An alarm with GPS and an engine block alerts your phone, shows where the car is and stops the engine from starting without your fob. ## How much protection your car needs **How much protection you need depends on the car** - **An older car:** OBD port relocation and a steering column lock. - **A car with a keyless key:** an immobiliser and a pouch that blocks the key signal, and against theft through OBD, port relocation or a port blocker. - **A more expensive car:** on top of that, an alarm and GPS. - **The car stays outside at night:** an alarm that alerts your phone.

If the car was unlocked or the key was inside, the insurer may refuse the claim. According to the Ministry of the Interior, from January to August 2023 more than half of the cars stolen in Belgrade were driven away with the key inside. The Ministry therefore calls on owners to secure their car with mechanical or electronic protection. Of the cars stolen in Belgrade in 2022, only about half were found. GPS shows you where the car is, so you can tell the police right away where to look. [More about GPS tracking](https://autoindustrija.rs/en/services/gps-vehicle-tracking) Some insurers give a discount on comprehensive insurance if the car has an additional anti-theft device. When you tell your insurer which protection the car has, they tell you how much it lowers the price. [More about the kasko discount](https://autoindustrija.rs/en/kasko-discount) After a theft, some insurers ask for all the original car keys and the keys of protection devices. If you do not hand them over, they treat the car as unlocked and do not pay the claim. So keep every fob you get with the protection.

GPS has two parts to the price: fitting the device and monthly tracking, which covers the SIM card and the app. With some offers the device is not paid separately but is included in monthly tracking. With some offers, once the contract ends, you can put your own SIM card in the device. When you work out what GPS costs you, add up the fitting and the tracking for 2 or 3 years. An alarm that alerts your phone has its own SIM card, so there may be a cost with the mobile operator. Keep an eye on the status and credit of the SIM card in the alarm. If the card is blocked, the alarm cannot alert your phone. The battery in the alarm and immobiliser fob is replaced when it gets weak. The device tells you, so replace it before the fob fails. ## What the price includes We'll tell you the price before the appointment, for each protection and for all of them together. You pay in cash or through a company. The price includes this: - **The device with every part your car needs.** When the alarm cannot see from the car electronics that the bonnet is open, we fit a separate switch on the bonnet. - **Hidden fitting.** A thief can switch off a unit he finds, so the unit is hidden among the car's cables. - **Setup and testing.** We check every function: doors, bonnet, engine block, the message to your phone and the location in the app. ## Frequently asked questions ### Why add protection when the car has a factory immobiliser? The factory immobiliser also accepts a new key that a thief makes through the OBD port. An add-on immobiliser also asks for your fob, so the engine does not start without it. ### Is more expensive protection always better? Better protection is the one that stops the way your car in particular is stolen. When a thief unlocks a keyless car with the signal of your key, an alarm that only sounds helps little. An engine block with a fob, an immobiliser and a key pouch help. ### Does protection get in the way of servicing and the roadworthiness test? Not when you know what to do. Before a service, put the alarm in service mode, in which the alarm does not interfere with the car electronics. After OBD port relocation, take the small adapter to the service and the roadworthiness test and plug it into the hidden socket. Before the roadworthiness test, switch off an electronic OBD blocker with a fob or a code. Have a question about your car?
