Hi peeps. Please can you help? I have an R reg 98 Cinquecento S 899cc. It has two keys supplied by the previous owner. Now I'm a little worried as they are both blue! One has a chip in it, the other just has a plastic head with FIAT stamped in it. The engine starts and runs no problem with the chipless key, does this mean the immobiliser (if I have one) is not working. The CODE key light comes on and goes out after a few seconds and all is ok. :bang: I need to know about the immobiliser side of things for my insurance renewal. Do I have one and what type is it? Many thanks in advance. anc

Hi there, since you're a newb I'll let you in on a secret.. There is a Cinq section dedicated to the Cinq!

I'll move you now.

If its starting without a chip key then it sounds like you have no immobiliser - or at least the transducer type anyway.

Maybe it was disabled or removed by the previous owner or something and they had also had a new key made, but not a chip type.

I'm sure the real experts will be along shortly

On insurance renewal just fill in the option saying 'standard factory fitted' for the immobiliser

I think you are missing the red key though.

The code coming on at startup and then going off after a few seconds is normal it should do that. If the light was permanantly on then you have a problem

Thanks for the replys and the move.
So, I have a blue 'FIAT' key and a darker blue chipped key with the letters JMA on one side and letters and numbers (code?) on the other side. The cars only had about 3 owners from new. What's the difference between a red key and a blue key with a chip? I kow I sound like a real dunce but my other cars don't have these new fan dangled security devices fitted, Lil' Jim is the newest car I've owned.

The red/maroon/burgandy key allows the blue keys to be reprogrammed, the car (i.e. the ECU) needs to be told the electronic number on each blue key. If it sees a strange blue key (or a damaged blue key), it will whirr the starter motor but wont start the car.

One is not supposed to buy with out the brown key...

Check the FAQs in your sig. There are different key systems for different years.

Check the specs given against yours.

I think that the sealed blue key also has a chip as your code light is going out.

Cheers

it belongs to me - those are my initials

What are the chances of finding the real owner as soon as I come onto a forum? Damn, I've been rumbled!!!
Anyway, here are my keys. The darker one has a chip inside.(sorry about the blurred pic)

Did you actually check the FAQS?

OK, checked the FAQ's. Now I'll have to dig out the Fiat owner's handbook I got with the car and see if her (the seller) phone number is on the reciept and ask if she might just happen to still have the key, plus she was a student living in a rented flat in a big old converted house in Sefton park so chances are she's not there any more!:bang: Still, her parents only live on the Wirral so it's not that far away if she still happens to have it knocking around. Thanks for all the info guys. I'm glad my other cars don't have this problem.:yum:
78 Mk1 Fiesta.
75 Mk3 Cortina.
72 VW camper.:slayer:

There might be a colour problem

The normal brown key is larger than the blue key and has a screw driver 'slot' to allow separations of the two plastic parts.

The normal blue key just looks like a normal - no intelligence- car key. I.e. it is stealthy...

Does either of your keys have a slot?

If one has a slot suggest you need to go to fiat dealers with both current keys and auto to get another unslotted key as the slotted key is worth a lot when you sell. Then lock it away somewhere safe.

Fiat will charge

Noel

No slot in the darker one and both keys are the same size. The darker one has a removable disc on one side and when you pop it out there is a chip inside. The other side of the key has:-
TP0
F1-13p5
on it.
The previous owner is no longer at her last known address but the current tennant has taken my number to pass on to her. I'm not holding my breath and the chances of a student keeping an old car key are very slim indeed I reckon.

*EDIT*
I've just noticed that the key with FIAT on the head has a symbol on the shaft of the key itself. A little triangle pointing into a target sort of circle pattern. Any ideas?

does it have a number 2 also? if it does thats the CODE2 immobiliser system which means there would be no extra key and what you have i.e. 2 blue keys is correct

So you didn't read the FAQS then!

Ok the symbol you descrive indicates it is a immobiliser capable key. This would be on a blue or brown key, (note not looked at my brown key).

I think you have a colour problem.

The normal blue key has an solid plastic handle you cannot open it up.

The normal brown key has a plastic handle that can be opened up, not brave enough to do this to mine.

Suggest you need to either practice walking, or take both your keys and auto to fiat dealer to get a 2nd blue key. You then put the brown key in a secure place, and dont lose either blue key cause you will be poorer.

If you damage the 'brown' key and lose or damage the blue key(s) you throw away the car or fit another ECU, (probably new steering wheel lock) and new set of keys, fancy selling a kidney, cause it is simpler getting a replacement sei?

If you lose a blue key the dealer can use the brown key to tell the car to ignore the lost blue key, the car knows the immoboliser codes of all of its own blue keys, they are all different.

This does not make a car thieves life any happier either.

Noel

P.S. I copy and paste

''''If the key has a transponder sign on it (Triangle with 2 little rings around the top) then it needs a master key. If it has a 2 on it, its a 2nd generation one and doesnt. If it has nothing then it dont need one either, according to Peter, chairman of FMCGB!

OK. Rallycinq, please tell me exactly what I'm supposed to be reading in FAQ's.
If you mean this, I've been there and it looks like I'm stuffed doesn't it?
https://www.fiatforum.com/cinquecento-seicento-faqs/93878-red-blue-black-keys.html
Neither key has a 2 on it. just the triangle/circle pattern on the non chipped key.
ps, anybody wanna buy a chinkychento?.......................or a kidney!??

Can you explain which bit of the quoted sentence you did not understand?

Was it the 'walk' or the 'take'

Even a second blue key will not be cheap, but you should not be using the chipped master key and certaintly should not be dismantling and inspecting it, unless you really like walking...

e.g. I dont think they are immune to static electricity.

I keep mine locked away.

Noel

P.S. You will get a good price for some of the bits in your car, but not for the ECU.
