General What’s the purpose of the small black key?

Hi all, hope yourselves and your Fiats are well!
So when I purchased my Fiat recently, the car keys came with a small black key on them. I’ve got the all-important red key, the blue key... and a smaller black key. The shape of this key is similar, but different to the others! Any ideas? Sorry if it’s a silly question! Please see image attached. Wondering if this is a replaced ‘silver key’?

Back in the days of the tipo.. same platform of the coupe..

It was the 'service key'

Opened the doors..and started the engine.

But DID NOT give access to the boot.

Yours having a 'Master and Slave' key set.. it is unlikely to start the car..

Does it fit the 2 door locks though?

Hi Varesecrazy,
Thanks for your reply!
Ah I thought it might be, I haven’t tried it in any locks yet - it looks so different, I didn’t want to risk it! I’ll have a go next time though!

Hey-

I think you'll find; dependant on version- this is for the alarm, if it's under the bonnet
