Broken Key Fob

[blind-in-texas]

Hello all, the night before last i misplaced my main clio key. i cant find the bloody thing anywhere. i got my spare (witch i haven't used before) and i found out the chip inside is buggered (it looks like the previous owner has tried a soldering bodge job and made it worse). so basically i can get into my car and turn on the ignition but the car wont start. I reckon its cos the imoboliser wont disarm itself due to the key being buggered. I'm wondering what my options are? i know i could take it to Renault but thats really costly. i have managed to source a full lock kit, ecu and transponder for my car it seems to be allot cheaper than getting a new key, would this work? or would i get away with switching the ecu and the circuit board inside mt key to save me changing the locks? Also the car started fine with the other key so its not the battery or anything. i have a good mechanical understanding but i don't have a clue when it comes to things like this. any help will be greatly received.
Thanks for your time to read my post,
Kris

Dose the imoboiliser light keep flashing fast? If so try pressing the button on the key fob when turning the engine over.
Hope this helps mate

Easiest is to get the key programmed by Renault and have it cut at a locksmith shop. Some dealers charge circa £40 to cut a key after they have charged you for programming it, cost upwards of £100 easily.

Proper locksmith shop will charge you no more than a fiver for cutting a supplied blank key

I'll find out tomorrow at work if there's anything else
