hi, sorry but i doubt the key from
is any good , i have approx 50 people who purchased 'good new keys ' from
, and not single one has worked. you cannot use a key from another car on yours, and i take it yours is a megane or scenic.?
do you have the correct code ? are you turning off the ignition and holding the central locking button down till the locks actuate before pressing the fob 3 times?
does your origanal key still work ok ?
think you will have to buy a key from renault.
