Have you ever wondered why some cars are stolen in minutes and others remain untouched for years? It’s not just the make or model – criminals carefully prepare for the theft, leaving behind subtle but critical clues. 9 out of 10 hijackings occur after preliminary reconnaissanceIf you know what to look for, the chances of saving the car increase significantly.

This article is not about abstract tips like “set the alarm” (although that’s important too). Here we'll take it apart. Specific Signs of Preparation for theftThe snails that criminals use right under your nose, from strange scratches on the body to suspicious technical failures. You will learn how modern hijackers work, what they do. The tags on the car mean "target set."What to do if you notice at least one of these signals. Spoiler: Sometimes it is enough to change the usual route or parking time to save the car.

1. Unusual marks on the body or glass: what they mean

One of the most common ways to mark a potential victim is to apply barely noticeable marks on the body, glass or wheels. Criminals use them as navigation beacons for accomplices. Most often, it's:

  • 🔴 Colored dots or crosses Red, green, blue on the rear bumper, doors or windows can indicate the make, model or even the level of protection of the car.
  • 📍 Scratches or scuffs in atypical places (for example, on the roof or under the bottom) – often applied with a “key” or other sharp object to indicate the target.
  • 🖊️ Inscriptions in chalk or marker On the asphalt next to the wheels (for example, the letters "Y", "G", "T") - codes for hijackers about the time or method of theft.
  • 🧲 Magnetic tags under the bumper or on the arches – can contain GPS trackers or simply serve as a landmark.

Especially dangerous are the labels that appear after visiting public placesParking at the shopping center, gas station or even car washes. Criminals often work in these areas, as it is easy to go unnoticed. If you find a suspicious mark, Don't wash it right away. Take a picture and check the car for any other devices (more on this below).

⚠️ Attention: Marks on Toyota Land Cruiser 200, Lexus LX and Mercedes G-Class Often appear in the first 2-3 days after purchase - hijackers track new cars through the traffic police databases and apply tags immediately after registration.

2. Suspicious activity around the car: who and why is watching

The hijackers rarely act at random - before the hijacking they conduct surveillance behind the car and its owner. Here are the typical scenarios that should alert:

  • 👀 Strangers near the car, which “accidentally” pass several times, take pictures or record on the phone (can fix routes or check the alarms).
  • 🚗 Cars without numbers or with tintingParked next to your car for days – often used to block a key fob or GPS signal.
  • 📱 People with tablets or walkie-talkie Parking – can be a “clean-up” (those who distract attention or jam signals).
  • 🔧 "Random" mechanicsFree diagnostics or assistance – This is how hijackers check if there are additional protections in the car.

One of the most dangerous signs is if you have a car. Parking several times in the same placeAnd then suddenly she disappears from her usual place. This could mean that the hijackers check the owner's response Not having a car (for example, how quickly you notice a missing car and call the police)

Type of activity What might that mean? Your actions.
Stranger takes pictures of car Fixing a model, number, damage to select keys or documents Go up and ask politely why he's doing it. Record his appearance on his phone.
Car with tinting is next to 2+ days Possible “cover” for a relevant hijacker or signal silencer Change the parking space, check the car for trackers
“Accidental” assistance with a wheel/battery Check for alarms, immobilizers or hidden tags Politely refuse, say they've already called a tow truck.
💡

If you notice suspicious activity, you should not immediately approach the car - the hijackers can be armed. It is better to observe from afar and record details (numbers, appearance) for the police.

3. Strange technical faults: when the car "goes crazy"

Modern hijackers are often used electronics to prepare for the theft. If your car starts to behave unusually, it may not be an accident. intervention:

  • 🔋 Unintentional disabling of alarms Or it's a no-cause operation, which could mean that criminals are testing its vulnerabilities.
  • 🔑 The central lock is locked/unlocked on its own. Sign of connection to the CAN bus or use of a “cloned” key.
  • 📡 Loss of keychain communication at a distance of less than 5 meters – possibly a jammer is working.
  • 🚨 False errors on the dashboard (e.g., Check Engine without cause) – can mask the connection of diagnostic equipment.

Especially dangerous are cases where faults are manifested after visiting the service or wash. Criminals often work in such places to gain access to the car. For example, on some models BMW X5 and Audi Q7 Hijackers connect devices to the OBD connector in 30 seconds – enough to remotely shut down the engine or turn off the immobilizer.

What to do:

  1. Check it out. OBD-II connector (usually under the wheel) for the presence of foreign devices. If you see an unfamiliar black box, Don't take it out yourself. (alarm may be triggered) and call the police.
  2. Turn off the bluetooth and Wi-Fi in the car – hijackers can use them for remote access.
  3. Check the connection history in the multimedia system (on some models) Mercedes and Volkswagen This can be done through the menu. Settings → Connections → Devices).

4. Changes in the behavior of keys and key fobs: alarms

Keys and keychains are the most vulnerable place in the protection of the car. If you notice something on this list, your car may have already been tagged:

  • 🔑 The key was worse to open the car. The first time, it may have been copied or replaced.
  • 📶 The alarm clock stopped working at the same distance. - a sign of the silencer or the connection of the duplicate device.
  • 🔋 The battery in the keychain suddenly discharged The hijackers can use powerful transmitting devices that “suck” the charge.
  • 🚗 Car reacts to neighbor's parking keychain - so your signal is cloned.

In some models (e.g., Nissan Qashqai or Kia Sportage) hijackers use field-attack: They intercept the key fob signal when you are at home and transmit it to a car standing in the yard. This way the car opens without breaking in. To protect yourself:

  • Keep the keys in. metal-box or screen-case (blocks the signal).
  • Turn off the keychain at night (if there is such a feature).
  • Check if the backlight on the key is on for no reason – this could mean someone is trying to “read” it.
⚠️ Attention: If you keyless Never leave your key near the door or window. The hijackers can pick up the signal even through the wall at a distance of up to 10 meters.

5. Preparing for theft through documents: how fraudsters get access

Not all hijackings are hot on the trail - some criminals act through the paper-substitution or registration fraud. Dangerous signals:

  • 📄 You are being called by the traffic police with a request to provide PTS data - so the fraudsters check whether the car is encumbered or wanted.
  • 💳 Someone tried to get a loan for your car. Check the history of requests in the credit bureau.
  • 🔍 Sites like Autocode have unfamiliar VIN checks - so the car was "watched."
  • 📬 You have received letters of fines for violations you did not commit. - Your numbers may have been cloned.

To protect yourself:

  1. Check your car ownership history through Public Services → Transport → History of Ownership.
  2. Set notifications about any activity with your PTS (some banks and services offer such a service).
  3. Don’t give anyone the original PTS – even in the service, a copy is enough.
How to check if your car is stolen or mortgaged?

Go to the site. GABD “Services” means “Verification of the vehicle”. Enter the VIN or the state number. If there is an entry “Arrest” or “Pledge” in the “Limitations” section, immediately contact the police – your documents could be forged.

6. Unusual "coincidences": when hijackers manipulate circumstances

Sometimes the preparation for theft is disguised as ordinary everyday situations. Be on your guard if:

  • 🚧 Your regular parking space is occupied by the same car forever. This is how hijackers block view or access.
  • 📅 You were suddenly offered a “profitable” parking in an unfamiliar place. - it could be a hijacking trap.
  • 🔧 Your car 'accidentally' has a scratch, and the culprit insists on 'quick' repairs This is how criminals get access to the car.
  • 📱 You received an SMS about the “winned prize” with a request to come to pick him up by car. A classic trick to steal a car along the way.

One of the most insidious methods. "fake accidents". Fraudsters deliberately create minor accidents (such as cutting you off), and when you get out of the car, an accomplice quickly steals it. If you were “accidentally” hit in the parking lot, Don't get out of the car. Call the police without leaving the salon.

💡

The hijackers often act as a team: one distracts the owner (requests for help, creates an accident), and the second at this time breaks into the car. Never leave your keys in the ignition lock, even for a minute.

7. What to do if you notice signs of preparation for theft

Have you detected any of the signals listed? Act on the algorithm:

  1. Don’t panic, but don’t ignore either. Even if it is a false alarm, it is better to be safe.
  2. Take pictures of any suspicious marks or damage - it'll help the police.
  3. Check your car for GPS trackers.:
    • Look at this. headlamp-covered, bumper-bar, seat-in.
    • Use a radio signal scanner app (e.g., Hidden Device Detector).
  • Change the parking space and schedule The hijackers are counting on the habits of the owner.
  • Install additional protections:
    • Mechanical steering blocker (e.g., Disklok).
    • A hidden mass or fuel switch.
    • Video recorder with security function (records movement around the car).
    • Call the police. Even if the theft did not occur, recording the fact of preparation can prevent the crime.

    If you suspect that the car has already been hacked (for example, find foreign wires under the panel), Don't turn it on. Some devices may lock the engine when trying to start. In this case, it is better to call a tow truck and take the car for diagnosis to a trusted service.

    FAQ: Frequent questions about preparing for theft

    Can you steal a car if it has an immobilizer?

    Yeah, but it's harder. Modern hijackers use:

    • Cloning keys through a diagnostic connector.
    • Substitution of control units (e.g., ECU or BCM).
    • Software vulnerabilities (on some of them) Ford and Hyundai The immobilizer can be turned off via the CAN bus.

    The immobilizer protects against amateurs, but not from professionals. Additional measures (mechanical locking, trackers) increase security.

    How to check if the car is GPS tracker?

    Use a combination of methods:

    1. Visual examinationCheck under the hood, in the trunk, under the seats, inside the headlights.
    2. Radio signal scanner: applications like Hidden Device Detector or GPS Jammer Detector (Android).
    3. Consumption verification: if the battery is discharged faster than usual, it is possible that the tracker is powered by the onboard network.
    4. Professional diagnostics: in car services there is equipment to search for "bugs".

    Pay attention to this. magnetobox The size of a matchbox – they are often attached under the bottom.

    Which cars are stolen most often in 2026?

    According to the Ministry of Internal Affairs, the top 10 most stolen models include:

    1. Toyota Land Cruiser 200 (especially diesel versions).
    2. Lexus LX 570.
    3. Mercedes-Benz G-Class.
    4. BMW X5 and X6.
    5. Hyundai Santa Fe and Tucson (Due to the vulnerability of the immobilizer)
    6. Kia Sportage and Sorento.
    7. Nissan Qashqai and X-Trail.
    8. Volkswagen Tiguan.
    9. Ford Kuga.
    10. UAZ Patriot (Popular for resale in the CIS countries).

    Also at risk. New cars (up to 3 years) car-and-car credit history (It is easier to sell them through fake documents).

    Does the “people’s” means of protection against theft help?

    Some methods work, others are a myth.

    Method Efficiency Explanation
    Steering blocker (Disklok) ⭐⭐⭐⭐⭐ It slows down the hijacking for 10-15 minutes, which is enough to scare off criminals.
    Secret button to turn off mass ⭐⭐⭐⭐ It's effective if it's hard to find. But the professionals know where to look.
    The inscription "Stolen - found" on the glass ⭐⭐ It may scare away amateurs, but it won't stop an organized group.
    Foil on the alarm keychain ⭐ It does not protect against cloning of the key, only from accidental operation.
    Video recorder with security function ⭐⭐⭐⭐ It captures the identity of the hijackers, but it does not prevent theft.
    What to do if the car has already been stolen?

    Act quickly:

    1. Call the police (102) and inform:
      • Mark, model, color, state number.
      • The location and time of the theft.
      • The signs of suspicious persons (if you saw them).
  • Activate the tracker (if installed) through the app.
  • Check the surveillance cameras near the place of the theft (mac, gas station, yard cameras).
  • Post information in local public places and on sites like ugon.net.
  • Contact the insurance company (if you have a “hijacking” policy).

    • Don’t try to find a car yourself. - it's dangerous. Give all the details to the police.
