We tell you before we agree a time. Payment cash or through a company ## How we fit it 1. 1 ### You send the car model Send us the make, model, year and city. Tell us how you unlock the car and what you want from the alarm: to sound, to alert your phone or to stop the engine starting without you. 2. 2 ### We tell you which alarm fits and what it costs The installation starts only when you agree. We tell you which alarm fits your car and what works on it. The price depends on: * What the alarm does: siren, phone message, GPS or remote start. * Whether an engine lock goes with it. * Which sensors go with the alarm. * The make and model of the car. 3. 3 ### We agree the time and place We agree the day and place of installation. Installation takes at least 2 hours. 4. 4 ### We fit and set up the alarm We connect the alarm to the car wiring and set it up for your car and the parts you chose. We route the cables through the wiring and protect them. 5. 5 ### We test the alarm and hand over the car Together we check the doors, boot, bonnet and sensors, and the engine lock and phone message if the alarm has them. You pay when we finish: cash or through a company. ### When you collect the car You get and we show you * A card with the PIN code, for switching off when the fob or remote does not work * How the alarm is armed and disarmed * How to prepare the alarm for servicing ### Important * **A siren is heard. An engine lock stops the start.** A thief can ignore an alarm that only sounds. When the chosen alarm has no engine lock, we can fit an immobiliser with it. [More about the immobiliser](https://autoindustrija.rs/en/services/immobiliser) * **A siren alone does not close the OBD port.** After [OBD port relocation](https://autoindustrija.rs/en/obd-port-relocation) the factory port does not work without your adapter. An engine lock that asks for your fob, code or card stops the start even when the car is unlocked. * **For a message from afar the alarm needs a SIM card.** The card must be active, and you pay the card costs to the operator. The control unit and shock sensor go under the dashboard, the cabin sensors up by the windscreen, and the siren and bonnet switch under the bonnet. ## Engine lock: the car will not start without you With the engine lock the engine will not start while the alarm is armed, or while your fob, code or card is not there. We connect the lock so it stops the engine from starting, and does not switch off the engine while you drive. The regulation on vehicle technical requirements also asks for that. ## Can the alarm work with your key? The alarm can read the doors, boot, bonnet and locking from the car electronics. Then it arms when you lock the car with the factory key, so you do not carry another remote. Such an alarm is called a CAN alarm. What works on your car, we check by the make, model and year. ## Does a car alarm drain the battery? An alarm uses a little power even while the car is parked. How much depends on the model and the parts that go with it. A Pandora with a SIM card can tell you when the battery voltage drops. ## After installation 1. **Keep the PIN code card outside the car.** That code switches off the alarm. 2. **Before servicing, switch on service mode.** The alarm then does not lock the engine, and you give the mechanic neither the fob nor the code. 3. **When the alarm goes off for no reason, get in touch.** We check what sets it off: a sensor, the battery, the battery in the fob or the bonnet switch.

Fob in your pocket: the engine starts Fob not in the car: the engine will not start ## Questions How much does a car alarm with installation cost? There is no single price, because the price is set by the alarm you choose and your car. The price covers the alarm, installation, set-up and testing. We tell you when you send the make, model and year, before we agree a time. What if I lose the fob or its battery goes flat? Switch off the alarm with the PIN code from the card you get after installation. We show you the procedure for your alarm at handover. Is comprehensive insurance cheaper if the car has an alarm? Some insurers give a discount on comprehensive insurance if the car has an extra anti-theft device. There is no single rule for all insurers. [More about the kasko discount](https://autoindustrija.rs/en/kasko-discount) Can I fit an alarm myself? We do not recommend it. The manufacturer recommends professional installation, because how the alarm works depends on it. A wrong connection can damage the car wiring. ## Which alarm fits your car?
