I have a R reg renault megane E RT 1.4, I changed the batteries in my key fob and now the key fob wont work, I cant turn off the immobiliser and the remote central locking wont work either. the light still works on the key fob so the batteries are ok. Any help or info would be great.

hold the cetral locking lock all button down until the doors lock and unlock. The imobilser light goes solid red. At this point you have 10 to press the botton on your key 2 times . the doors will unlock and lock.
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.
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
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.
work it manually and it should work ...ie put the key in the door and open and lock the door 3 times slowly then jump in and try to start within 15 secs .if it doesnt work then be prepared to be fleeced and lay the golden egg at the dealers
