The spare key does exactly the same as the normal key i use!
Clio 172
When my key went the spare also did the same. I put it down to the spare was the original key and had failed, so a previous owner had started using the spare and just put the original now faulty key as a spare (swapped a faulty key for the spare)
I had a new key sorted at Renault, cured all problems and both the keys that come with the car still produced faults

Immobiliser Issue
Golf GTD Mk7
Immobiliser issues tend not to have anything to do with the immobiliser
Yep mine was to do with the 12v feed to the decoder ring

Ah ok cool, that sounds like a serious amount of effort, ill see what the damage is at Renault, should hopefully get it there today....

You wont be saying that when renault give you the bill
Good luck all the same. Changing the ECU, UCH etc is very easy to do fyi

Well its going for a diagnostic, they have told me that they will not do any work until they know the cost and fault.......apparently
I'v had this problem, I turned the key one click so that the heaters came on left it for about 30 seconds took the key out tried again and it starts fine first time 
But it does seem to be a reoccurring problem when its cold, which when you live in wales is quite often....

After 2 hour diagnostic at Renault they have told me the UCH is shot, £400 part & fitting booo....
I could buy the whole lot off ebay but to be fair I have two keys and need two keys so figured I could probably do it second hand for around£200 but how long would a second hand UCH last when all the N3's are probably already 10 years old, so Ive bit the bullet and told the Renault guy "order the part"
First problem since ive had the car after 6 years!

and ECU...
Liquid Yellow 1.5DCi
My DCi been giving me the flashing light treatment every now and then with my 'main' key, but is fine with my spare. Judging by how much that UCH thing is I hope mine isn't gonna think about packing up. Glad u got to the bottom of it tho.

Picked the car up I'm £400 poorer but I have a car which runs spot on again!

Apparently a knackard UCH the car was checked on a diagnostic machine and after a couple of hours they found the fault!
At least I now have a bit more faith in the car and luckily I didn't get stranded anywhere!!
