My renault laguna 1999 rt remote key fob wont work?

Question edited for typos (magan) (stoped).

The fob needs to be reset. If this doesn't work, drop into a place that fits car alarms, or if you service at a dealership, they ought to do it for free.

keys into ignition turn to number 2. press fob. doors lock press again doors unlock. turn ignition back remove key. press fob lock doors wait 5 seconds press fob to open doors. then try ignition again. should work. if not then there is something like a chip missing from the key or the ring reader on the ignition is not working.

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.

Assuming the car battery is ok (if not, buy a male to male cigarette lighter at the auto store and connect to another car until charged enough to unlock the doors...but don't try to crank the ignition!). The trunks won't open if the battery went dead with the alarm set because arming the alarm physically locks the releases.

Sounds like the key code is switched off because you replaced the key fob battery. Try unlocking the car manual with the key in the door lock. Then switch the ignition on to reactive the keyless entry. If this does not work, you might also try pressing the fob unlock button with the key in the door lock until the dash led flashes.

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

i presume little led in fob flashes when button pressed. Key needs to be initialised. Put key in door lock or ignition barrel and press unlock button watching led on dash, this should flash. remove key from lock, remote should now work
