What relocation stops, and what it does not
Relocation stops
- A new key through the OBD port.
Important
- Keyless theft. Thieves catch the signal of your key and relay it to the car, so they do not need the port. A key pouch and an immobiliser help.
- Attack through the headlight. On some cars a thief uses the cables near the front light to send a fake message that the key is genuine. An immobiliser or an alarm that blocks starting helps.
- Have a more expensive car? For the OBD port we fit relocation and a blocker, and for the whole car an immobiliser and GPS.
How a thief makes a key through the OBD port
The OBD port is where the workshop plugs in diagnostics. On the same model it is in the same place, most often under the steering wheel, so a thief knows where to look.
The thief gets into the car and plugs a key programming device into the port. The device programs a new key. The thief starts the engine and drives the car away, often in a few minutes.
Workshops use such devices, and they are also sold online. The factory immobiliser accepts a key programmed into the car.
How it differs from simply moving the port
With simple moving, the port is only shifted to a hidden place. The thief only has to find it.
With us the factory port stays intact and in its place. The thief needs both the hidden port and your adapter.

Questions
How much does OBD port relocation cost?
100 € for every model. Coming to your address in Belgrade is included. Other cities we agree by phone.
What is the difference between relocation and the electronic blocker?
Both stop a thief from making a key through the OBD port. The difference is what you do when you go to the workshop. With relocation you bring the adapter. With the blocker the port stays in its place, but it does not work until you switch it on. More about the OBD blocker
Do I get a discount on comprehensive insurance?
Some insurers give a discount if the car has extra theft protection. Before signing, ask your insurer whether OBD port relocation counts as such protection. More about the kasko discount
