How to bypass a Renault car immobiliser using its bypass de-activation code, for use with cars that have an infra-red key.

...

What is it?

Some Renault cars have an inbuilt system that enables you to override the immobiliser should the infra-red key fob cease to work. This is useful to emergency and recovery services should they need to move a dead vehicle.

The Immobiliser Bypass Code is a four digit numeric code that is unique to each car. This code can be obtained by running a small downloadable Microsoft Windows 32 bit software application and entering the specifics of your car.

This technique can only be used to override the immobiliser on a vehicle for which you have the key or key number so don't go thinking you can use this method to steal cars!

So, if you have found that the infra-red key fob for your Renault car is no longer de-activating the immobiliser, this bypass technique can be used as a temporary work around to start the car until you can get it fixed properly by a dealer.

Why are you giving away this information?

It is true that some people on internet forums and auction sites are charging for this information.

Your car is important to you and I believe that if your car has been rendered undriveable through no fault of your own and a quick easy fix is available you should not be held to ransom by someone wishing to make some profit.

I hope that you find this information useful and perhaps even use it to get yourself out of a sticky situation.

How does it work?

The application that is available for download at the bottom of the article, will enable you to find out what the immobiliser bypass code is for your car. Once you have the code you can use it for as long as you need, there is no limit as to how many times you can enter it.

Don't wait until you are stuck in the middle of nowhere wishing you had your code. Get it now and keep it for when you might need it.

Will it work for me?

To find out if this system will work for your car, try the following test:

If your vehicle has a central locking button on the dash/centre console:

1. Switch on the ignition.
2. Press and hold the central locking button.
3. If the immobiliser light stops blinking and changes to a slow flash, this system will work for you.

If your vehicle does NOT have a central locking button on the dash/centre console:

1. Switch on the ignition.
2. Press and hold the accelerator pedal (you may also need to press the button on the end of the windscreen wiper stalk).
3. If the immobiliser light stops blinking and changes to a slow flash, this system will work for you.

If you cannot get the immobiliser light to change to a slow flash, this system will not work for your car.

How do I do it?

Entering the bypass code:

If your vehicle has a central locking button on the dash/centre console:

1. Download the ZIP file that contains the RenaultImmCode.exe application from the bottom of the article.
2. Extract the two files from the ZIP file and read the ReadMe.txt file which contains some simple instructions.
3. Run the RenaultImmCode.exe file and enter your car type number.
4. Enter the code on the sticker inside your key or the key numbers from the front of your service book.
5. Make a note of the four digit bypass code which should be displayed.
6. Press Enter twice to exit the application.
7. Get into your car, switch on the ignition and hold the central locking button down and the red immobiliser light will start to flash slowly.
8. Count out the number of flashes and release the central locking button when it matches the number of the 1st digit of your bypass code.
9. Now hold down the central locking button and count the flashes up to the 2nd digit of the bypass code and release.
10. Repeat the above step for the 3rd and 4th digits.

Re-synching the key fob (may not always work):

• 1. With all bypass digits entered, turn off the ignition.
  2. Hold down the central locking button. The immobiliser lights should remain constantly on.
  3. Point your key fob at the IR sensor near the internal rear view mirror and press on/off quickly. Hopefully the key should now be re-synched.
     If it is not, wait for the immobiliser light to start flashing and try steps 12-13 again making sure the ignition is off. It may take a few goes or may not work at all in which case you'll have to see your dealer to have it reprogrammed.
• If your vehicle does NOT have a central locking button on the dash/centre console:

If you don't have central locking you just need to substitute the pressing of the central locking button with the accelerator instead in the above instructions (you may also need to press the button on the end of the windscreen wiper stalk.

How do I find my car type?

UPDATE: Many people have commented that the car type number is not required. They have either entered their car model i.e. 'Megane' or just entered something random.

It would seem then that all you need is the key code so if you are having trouble finding your car type then you can try it anyway.

Your car type number will be printed on the Oval Plate which has been used for the identification of Renault vehicles since 1909. The location and design was changed several times during that period.

In vehicles produced before 1995 You will find the oval plate in engine compartment. It is made of aluminium and can be located separate or together with obligatory Vehicle Manufacturer Plate.

In vehicles produced after 1995 the Oval Plate is made from plastic in form of sticker located on right side middle door pillar. It can be seen by opening front passenger door.

If you have trouble finding your car type number, some people have been given it by their dealer.

Update: One person in the comments below has reported they entered the model of their car 'megane' and it worked for them.

From 1997

The car type number is indicated by the number 9 in the diagram below.

From 1995

The car type number is indicated by the number 8 in the diagram below.

 

Before 1995

The car type number is indicated by the number 1 in the diagram below.
