can a mod please make this a stiky i comes up so many times a week



a mk2 punto should come with 2 blue keys if not beat the seller down buy 100 quid

Either 2 non remote keys or one may be a remote key depending on trim level

these keys are roiling code as such the code stored on the key is mathematically changed by the car every time the key is used in the ignition

fiat can program anything from 1 to 8 keys to your car without the need for any of the original keys(like for example if you lost them all fiat can still rescue your car) these keys can be all remote non remote or any mix of keys you fancy

if you lose your only key don't try and break into your car as the keys come ready cut from fiat and can be used to open the car then it can be toed to garage and new keys programed'

some dealers will even come to you with the equipment needed to fix your car

now here's the main reason i wrote this threat

i see this asked to many times on here "can Timsons and such make a key for my car and program it yada yada"

simple answer no no one but fiat can program keys to your car no matter what they say they simply can't

i believe there are some places that can make an identical copy of a key you have but as i have said it's roiling code so as soon as you use the copy it will stop the original key from working and render it useless from then on

but even this is a little far fetched as i don't think any company's have made keys with reprogrammable memory and even if they can due to the problem i have outlined above they would be no market for them anyway

a few more facts about these keys

only fiat equipment can program the keys to your car so it's gona be a visit to the dealer either way

keys that are ordered for a car can be programed to that car only and cannot be fitted to any other car so if you start mixing lock sets or body computers about it's not gona work

all keys need to be present when new keys are being programed to the car otherwise they will be lost from the car's memory and will be rendered useless even fiat cant reprogram them after this happens as they're not new any more ie the rolling code has been changed many times and the car will not accept them

bit like when you take a baby rabbit from it's mother it wont want it back it will simply kill it

when ordering keys from dealer you will need proof of ownership like v5 document and some id probably not sure exactly what but dealer will tell you

you will also need to produce your code card if you have it many British cars don't as they are taken out at bristal buy fiat uk due to British insurance laws stupid if you ask me as no one can use it to steal your car anyway unless they have a blank copy of your key and know the emergency start-up prosedure these cards cost 10 pound so expect the bill to be 10 quid more expensive

i have seen some quotes on here of 130 for one non remote key this is quite frankly a rip off so shop around a bit play dealers off against each other

one not remote iirc should be about 84 quid all in programed an all

now could some people that have had these keys programed to there cars please give a better idea of what they should cost obviously remote keys are more expensive than non remote

so please specify what exactly you had done and how much it cost you thanks

please note the above is also true for any fiat fitted with code 2 keys and imobiliser
 
will this maybe the reasen why my car keepe cutting out well after changing coil csc and ecu with no luck and no code stored on obc my only last option is to order a new key will keep all you posted

no cutting out is probably a crank sensor

key codes do not cause these cars to stop

as once it's started it's happy with the codes after that stopping is another problem
 
I paid somewhere in the region of £160 for two remote keys, the programming card mentioned (no card was provided when I bought the car) and programming about 18-months ago.

As OP says you need V5 document, proof of identity (in my case my driving license was asked for), and it takes about 4-5 working days for the keys to arrive.

that's an excellent price thanks for the post

also did you get to keep your code card

many dealers chuck them after they have used them not sure why

so anyone going to get some keys programed make sure to ask for the card as you have paid out for it so may aswell have it

it will allow you to start the car in the future if the code system fails

timsons may well not be able to code the keys into the car you was saying only main dealer can do this.this is not correct as most ALA auto locksmith assocation members can do this.and some MLA, MASTER LOCKSMITH ASSOCATION you do not need main dealers to do most car keys and the remotes ie bmw/audi say main dealer only but they can be done by locksmiths same day with out any help from the dealer with no imobilizer code or key code

I second this.
hope it helps.

not true for fiat your thinking of code one keys that can be duplicated made and programed with ease

not code 2 rolling code it's impossible

there is the cars code required there is a code within the fiat examiner required then you need the can interface hardware software a means to get hold of roiling code key chips ad keys then you need a code from the body computer to put on the key for the car to except it as one of it's keys then you need to give the key another code and the car simultaneously to start of the rolling mathematical code sequence whilst not losing any other keys from the ecu

you have heard complete rubish

if it was posible i would be the first to tell of a loop hole to the system but it's just too tight
 
Related to the imobiliser code:

Does anybody know the reason why the code light will sometimes light up when the car is running? (i.e. will start fine with light going out etc.. then further down the road it will light up again but car will still work as normal)

In the manual it says a self test, is this true? whats it for? why it happen? etc..

If I bought keys with an incorrect key code, is it possible to get the code reissued for the keys?

Local dealership said it was possible, but was vague on details.
 
I bought a set of Mk2 keys + locks for my punto over ebay and they came with a key code card, now I am under the impression that this code is programmed to the immobiliser, but was told by the dealership, this code isn't right for these keys, I then contacted the seller who said it could be one of these three codes and supplied the codes but the dealership has said he can't put them on and bamboozled me with the reason why stating that if he put them on and it didn't work it would wipe my immobiliser, he would then have to install a brand new immobiliser and lock set...right oh mate. Said he could try and reprogram the key itself to the current immobiliser code but might not work (I thought I read on here that the keys themselves were not able to be reprogrammed).

Basically I have this lock set installed everywhere except the ignition barrel and want to know quickest safest way to get it all working. To me that means ordering the correct code for the key.

Hello, this is my first posting on your forum, so please forgive any transgressions of protocol. However, I had to intervene when I saw this thread. I am an auto-locksmith, and I regularly make keys for fiat cars and vans - including code 2 based systems such as those on Punto 2, Ducato 2, Idea and Stilo. I can also do the new Panda and Grande Punto which use an even newer transponder system.

Most of the information you have is correct, however some of it is wrong, and I'd like to correct it if I may.

The newer systems are not rolling code, but crypto code. Each time you start the vehicle the car sends a request to the key. The key does a computation and sends it back. Its up to the car to ask a different question each time.

The transponder chips (which live inside the key) cannot be duplicated, that is correct (at the moment). Also new transponder chips need to be precoded to the vehicle prior to coding to the vehicle with diagnostic equipment. However, I can get both the precoding info for the transponder and the code itself from the vehicle. I do this on an almost daily basis. It does not affect subsequently getting keys from the dealer.

This service is available from very few auto-locksmiths. I travel over a large area programming keys to vans which cannot afford to be off the road. Most auto-locksmiths can only program a dealer supplied key and code to a car.

I offer a same-day roadside service, and over 95% of all jobs are complete in one, two hour visit. The downside is the work involves much sophisticated equipment, and so is not cheap. Most of my work is when all keys have been lost, as Fiat take 5 days to get you a key, and then you need to tow the vehicle to them for programming.

Remotes to my knowledge are still the exclusive domain of the dealer. I can program them, but they have to come from the dealer.

I hope that clarifies the situation, and has not come across as an advert. If people have further questions that I can answer, please ask. I wont give out prices on this forum, or security information, but I am happy to dispell any myths.

Rickey.

A work around

My wife's Mk2 came with only 1 blue key. Here's what I did to enable us to have a key each.
Fortunately the car has no remote locking so the key is just a plain transponder key with no buttons. I got a local locksmith to make 2 keys for me the operate the locks mechanically. I then removed the lower cowl from the steering column giving access to the ignition lock and tried starting the car with the one of the new keys and with the transponder key held along side the ignition barrel to find out how close it had to be to the immobiliser aerial. Unfortunately it had to more or less up against the aerial which is in a plastic ring around the top of the ignition barrel. So I unclipped the aerial from the barrel, cable-tied the transponder key to it so that the blue handle part was in the centre of the aerial and checked to see that the car would now start with the new key. I did :)
I then cable-tied the aerial with the original key attached, out of site above the ignition barrel and re-fitted the cowl.
So we now have a key each and the car is perfectly happy and although the security is compromised slightly, nobody knows the key is in there.
