Renault Laguna

Moving House, car doors won't open. Excellent!!

What do I do next? Please help. I know that the keys are fine, just changed battery, spoke to some electrical engineers today, and they suggested that it may be the car battery itself??

Not sure, can I get into the car, or will the alarm go off?

Would appreciate some advice, many thanks Vicki

i had the same problem with a Renault 19. I had to strip the door cards off, and spray cleaner/oil over all locking mechanisms. It worked a treat but took a couple of hours...

Renault Laguna – Key/Immobiliser Reset Procedure

Things to have:
· The keys
· The Code for your Particular car (Renault can provide) eg. 8422
· The Car ( J )



Step 1
Turn the ignition on to illuminate the console warning lights.
Step 2
Using the interior central locking button, press and hold until the small led flashes…
i.e. if your code is 8 4 2 2 you will press firstly until it flashes 8 times then 4 times etc.. until the full code is entered.
Step 3
With the key removed, push and hold the button for a few seconds, the doors will cycle this sets the decoder in the footwell.
Step 4
Finally, aim 1 or both keys at the sensor, near the mirror, push several times to set the keys.
Step 5
Hopefully barring errors, enjoy your happy moments of opening and closing doors while getting the car to start. J



In emergencies there is a code that can be entered, this code will allow the car to be started and driven for approximately 10 mins… I will be honest I don’t know if this is the same for every Laguna but my code is 1313.
The emergency code can at least get you to the local Renault dealers where they can tune the keys properly.

Hope this helps you in future !!!
