How your immobiliser system works on Renault Laguna
Before explaining the different solutions available to you, here is a short introduction to show you the goal and operation of the immobilizer in your Renault Laguna. This electronic component appeared 30 years ago and aspires to prevent the theft of your Renault Laguna. In fact, thanks to a transponder and an antenna (coil) integrated in the key, and, a immobilisation control box integrated in the ECU and a reception antenna on the neiman, your Renault Laguna will go each time you insert the key in the ignition, it controls that the code emitted by your key is in fact the one asked by your immobilization box. It is only at this moment, that it will allow you to start. It is thanks to RFID technology (chip in the key) that this device will work.
The different alternatives to bypass the immobiliser on your Renault Laguna
Enter the code to turn off the immobiliser
First methodology, your key no longer allows your Renault Laguna to start, you want to turn off the immobiliser of your Renault Laguna, but first of all you should try this process to start it and take it to a mechanic check that you can not do a less important operation to bring back the normal start of your automobile. In fact, with your automobile you should have a spare key (which you should try and which should start your Renault Laguna), 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 automobile 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 validate the digit and resume, duplicate the operation until you have entered the entire code. This should allow your Renault Laguna to start without having to remove the immobiliser.
Repair your key at a key specialist or your car dealer
If even though a battery change, several attempts to enter the immobiliser code on your Renault Laguna still doesn’t work, it’s almost certainly your key that’s at issue. We can understand that you still want to bypass the immobiliser system from your Renault Laguna. In fact, 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 dealer who can repair your Renault Laguna key. Based 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 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 Laguna.
Manually remove your immobilizer
Although you may be thinking to bypass the immobilizer from your Renault Laguna, this is not recommended at all for different reasons. First your Renault Laguna would be much more vulnerable to theft attempts. In fact, without an immobiliser box, simply doing “the wires” may be enough to start it. Moreover to that, your insurance, in case of theft most likely won’t refund you if it finds out that the immobiliser on your Renault Laguna has been removed, bypassed or deactivated. This if you still want to do it, some sites still give the methodology, we have made the choice not to disclose it, because it could benefit people with bad intentions.
