Technical Blue key replacement

[trumpeter]

Hi all,
Is there any one out there who can help me.
I need to replace one of my blue keys as the alarm button works intermittently.
I have the red key and a small silver plastic tag with a letter and 4 numbers on it. I think I am missing the 2 round keys that disable the alarm.
Is it still possible to program a new key to operate the alarm without the 2 round keys??
Fiat told me i also need an alarm code which was on the tiniest bit of paper wrapped around the original keys. The manual mentions nothing about this.
Any help would be appreciated.

Fiat can get the alarm code for you if you have your V5. (£20ish) You can then program a new blue key using the button on the front interior light cluster. There is a risk though that your alarm has timed out for security reasons. It is then a dealer job.

Thanks polecat. I am now even more confused.
My alarm still works as i have one fully functional blue key and the one that is playing up still works sometimes.
I need 2 keys as i need to use the car while my wife is at work so it saves picking up and dropping off keys.
My main dealer says that i need the alarm code but a smaller local fiat specialist says i don't.
I also looked in the fuse box area this morning and i do not have an alarm disable key switch in there. (now i know why i don't have the little round keys!)
Nothing seems to add up with the manual for the car and what i am being told.
Can some one please help me sort out what i need and what i don't.
If anyone has an old blue alarm key with a good microswitch i could just swap that over and my problem is solved.
