How your immobiliser system works on Renault Koleos

Before explaining the different alternatives available to you, here is a short introduction to explain the aim and operation of the immobilizer in your Renault Koleos. This electronic element appeared 30 years ago and intends to prevent the theft of your Renault Koleos. Indeed, thanks to a transponder and an antenna (coil) included in the key, and, a immobilisation control box included in the ECU and a reception antenna on the neiman, your Renault Koleos will go each time you place the key in the ignition, it controls that the code emitted by your key is in fact the one required by your immobilization box. It is only at this moment, that it will let you turn on your car. It is thanks to RFID technology (chip in the key) that this device will work.

First methodology, your key no longer allows your Renault Koleos to start, you want to deactivate the immobiliser of your Renault Koleos, but first of all you should try this technique to start it and take it to a garage check that you can not perform a less important process to reestablish the normal start of your vehicle. Indeed, with your vehicle you should have a spare key (which you should try and which should start your Renault Koleos), but if you don’t have it you should at least have the “code card”, it contains the start code. Thanks to this code, you will still be able to start your vehicle by entering it manually. To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to confirm the digit and resume, duplicate the process until you have entered the entire code. This should enable you to start your Renault Koleos without having to remove the immobiliser.

Repair your key at a key specialist or your dealer

If in spite of a battery swap, different attempts to enter the immobiliser code on your Renault Koleos still doesn’t work, it’s likely your key that’s at issue. We can understand that you still want to bypass the immobiliser system from your Renault Koleos. Indeed, your transponder must have been affected or must have fallen off your key. To resolve this problem, only solution, go to a key specialist (also available on the internet) or, at your car dealer who can restore your Renault Koleos key. Depending on who you go to the repair should cost you about 100 euros if you still have a copy or your “code card” and about 350 euros at your car dealer if you have no support and you want a new functional key, it will avoid you having to remove the immobilizer from your Renault Koleos.

Manually remove your immobilizer

Although you may be tempted to bypass the immobilizer from your Renault Koleos, this is not recommended at all for several reasons. First your Renault Koleos would be much more vulnerable to theft attempts. Indeed, without an immobiliser box, simply doing “the wires” may be enough to turn your car on. Additionally to that, your insurance, in case of theft most likely won’t refund you if it realizes that the immobiliser on your Renault Koleos has been removed, bypassed or deactivated. This if you still want to do it, some sites still give the technique, we have made the choice not to disclose it, because it could benefit people with bad intentions.
