what does the light do?

i had a problem with the immobiliser on my clio once.. they only way i could start it was if i pressed the button on the fob as i was turning the key.

jump start the battery, disconnect it, theres some wires under the passenger side dash, pull them out, find the one for immob, disable it, either should do trick

the light flashes on the key when you press it,but theres no noise to it,cant unlock/lock the car with it,have to do it manually.

try changing the battery on your key fob!

scroll down to renault then write immobiliser in the search bar

hi there its a renault scenic r reg 1998

Sounds like your chip in your key needs reprogramming.

My dad had a similar problem with his immobiliser diff car tho it was the battery in the key fob not sendin string enough signal hope it helps

First ensure that when you unlock the car, you try to start it within 30 seconds, otherwise re-blip it. Otherwise look on renaultforums.co.uk as it is a common problem unfortunately on that year Scenic.

I'm pretty sure this can only be reprogrammed at the stealers - nearly 100% certain.
