Clio 172 2001 key not deactivating alarm and immobiliser. Please help

[JELMorgan]

Hello,

Went to unlock my 172 today and doors unlocked but alarm and immobiliser didn't deactivate.

I have checked the battery in fob and all fine.

Anyone have any ideals what's wrong. My spare key is broken so can't try that. Could the key fob of lost it's codeling with the alarm/immobiliser?

The alarm just keeps going off when I open a door and obviously immobiliser is stopping car starting.

Thanks in advance for your help.

My no 1 key that I used stopped working, but my spare works fine, so yeah I guess keys can just die.

Cleaned all Relays up which are next to battery and all fine now. Corrosion found on relays making poor connection.
