OBD protection

OBD protection stops a thief from making a new key through the port under the steering wheel. We fit 2 kinds: relocation and an electronic blocker.

Send the make, model and year.

We work in several cities in Serbia. Tell us your city.

Relocation or a blocker: which OBD protection you need

A small OBD adapter: a socket on one end of a short cable, a plug on the other

100 €

for every model, coming to your address in Belgrade is included

Electronic OBD blocker

Do you not want to carry an adapter to the service?

The price depends on the device and your car. Devices differ in how they are switched off and what they block.

  • The port stays in place, but does not work for the thief.
  • For the service you switch it off with the immobiliser fob, your alarm or an adapter.
  • From outside you cannot see that the port is blocked.

More about the electronic OBD blocker

An expensive car, a frequent target for thieves? Relocation and a blocker together, and for the whole car also an immobiliser and GPS.

Servicing and the technical inspection after OBD protection

Servicing and the inspection go as before. Before them, do one thing:

  • Relocated port

    Plug the adapter into the hidden port, in the spot you were shown after fitting. After the check, take it out and keep it with you.

  • Electronic blocker

    Switch the blocker off with the fob, through the alarm or with the adapter.

At the technical inspection the exhaust emission equipment is checked through the OBD port. More about the inspection and OBD

Keep the adapter and the fob outside the car

A thief who finds them in the car can switch the protection off himself. Lost the adapter? We come to your address and restore access to diagnostics. More about a lost OBD cable or adapter

A diagnostic device screen: a message that it cannot connect to the car's computer
Without the adapter: it does not work
The same device's screen: it checked all the car's computers, working ones green, faulty ones red
With the adapter: the service works

How a thief makes a key through the OBD port

Through the OBD port a mechanic reads faults and makes new keys. A thief can buy the same device.

  1. A broken car side window, close up
    1

    The thief gets into the car

    Through a broken window or doors that were left unlocked.

  2. The factory OBD port on the lower edge of the dashboard, above the pedal and the floor mat
    2

    He finds the OBD port

    On every car of the same model it is in the same place, most often under the steering wheel.

  3. A hand plugs a laptop cable into the port under the steering wheel, the laptop open on the lap
    3

    He plugs in a device

    He programs a new key into the car, and the car accepts it as its own.

  4. The engine start button in a car, the green light on
    4

    He starts the engine and drives off

    All of this takes the thief a few minutes.

The factory immobiliser does not help here

The car learns the new key and from then on treats it as genuine.

Petrol cars from 2001 and diesels from 2004 have an OBD port. More about OBD car theft

What OBD protection does not protect against

These 2 thefts do not go through the OBD port. For them we fit an immobiliser alongside OBD protection: the engine will not start without your fob, code or phone.

Questions about OBD protection

Does my car have an OBD port?
Yes, if it is a petrol car from 2001 or a diesel from 2004. It is most often under the steering wheel, on the driver side. More about where the OBD port is
Can I have both relocation and a blocker?
Yes. On expensive models that are frequent targets we recommend both.
Can a thief find the hidden port?
Even then he needs your adapter. The adapter is with you, not in the car.
How is relocation different from simply moving the port?
When the port is simply moved, it goes to a hidden spot. A thief just has to find it. With us the factory port stays intact and in its place. A thief needs both the hidden port and your adapter.
What if I forget to switch the blocker off?
The service device then cannot connect to the car. When you switch the blocker off, the port works again.
What if I lose the adapter?
Call us. We come to your address and restore access to diagnostics. That is why you keep the adapter outside the car, always in the same place. More about a lost OBD cable or adapter
Is there a lock for the OBD port?
Yes. The port is under a cover with a lock, so a thief sees the protection at once. Before the service and the inspection you unlock it.
Does a factory alarm protect against theft through the OBD port?
Mostly not. With a new key the thief unlocks the car like the owner, so the alarm does not react.
Do I get a discount on comprehensive insurance?
Some insurers give a discount if the car has additional theft protection. Before signing, ask your insurer whether OBD protection counts as such protection. More about the kasko discount
OBD or ODB protection?
It is the same. The correct name is OBD, from the English “On-Board Diagnostics”. ODB is a common typo.
