I had the same problem with mine

your key fob is now out of sync with the ECU to sync them just follow this link (renault will charge up to £180 for new key and to sync it)

    Also check the led transmitter on the keyfob is working. do this by looking through a camera lens on your mobile (as your eyes cannot see the light emitted) and look for a white flash when you blip the keyfob! if this is ok then follow the link above. if not take the fob apart and just resolder the LED (these tend to come apart after a while) hope this helps

You need to re-weld the transponder in the key
you have to open the key carefully with a cutter

I changed the batteries in the key fob of my renault megane scenic and now it does not work and i cant start the car, can i bypass this? the year of the car is 1999.


i have not tried this myself but i have been reliably informed that it should work on the 99 renaults

With ignition off, press and hold the key fob button, after about 10 seconds the light on the key will stop flashing, press the key fob button three times and if the key will resyncronise it will at this point operate the locking system.

My central locking on renault megane not working from fob and cant turn immobiliser off.


sounds like its time for a new fob, try useing the key to unlock the door this should shut down alarm, if its the key fob chip your talking about then hope you have a spare if not, depending on the year may need to reprogram a new key fob.

the pins on the lazer bulb in your keyfob has snapped off caused buy pressing the button too hard. (the red light will still come on but the key wont work)

heres what to do

open your keyfob and pull the lazer bulbs pins to the other side of the chip board. solder it to the wrong side where you see the nipples (dont worry there still in the right place) and shove a bit of bog roll in there to stop the chip board moveing when you press the button

Changed battery in key fob now unable to turn immobiliser off on my renault megane coupe s reg


there will be a combination of button presses required to reconfigure your fob to the immobiliser. you dont need to get it recoded so dont pay for it. try these:
hold the a button down for ten seconds until the light comes on constantly. then press it twice quickly and it will reprogram.
or press lock about ten times, then open ten times. this should work.
i had this problem on a rover and just pressing the buttons loads of times may allow it to be reprogrammed.
also check the battery isnt upside down in the fob.
