General KEYS Question

[daithi]

Hi Jug,
Thanks for the advice. I wasn't very clear. Yes i intend to buy the Meta M20 Remote Central Locking Relay and install it in my glovebox. What i wanted was some kind of integrated key and central locking clicker in the one unit that would work with the Meta M20.

I've had a look on abacus alarms but the only key with clicker they have is kind of ugly and i really liked the Stilo Key but realise now that its code system 2. Ah well.

i see. well in that case you could take the PCB from inside the M20 remote and stick it inside a stilo key. if the button is in the correct apcle, and it fitds, then this will work. the immob chip is very small so fitting that insude as well would be easy. fitting the metal blank would also be easy. its worth a try, but at least find a key with the button in the correct place.

Hello all
This is my first time on here , i am in a bit of a pickle , i have lost the keys to my Brava, i have changed the steering lock from a scrap car,(red key) also i changed the little box i think it is called the lock box and the ring around the steering lock,but it still won't start
Do i need to change the ecu of the same car if so could anyone tell me where it is positioned
Thanks
Mick

 

[jug]

yes you also need the ecu from the same car you took the code box and red key from.

the ecu is paired with the codebox

the location will depend on the model, for example on the 1.8 it is in the interior fusebox area, on the 1.6 it is next to the engine (on right when looking in engine bay)

Thanks for that info Jug,
By the way does the immobaliser stop the fuel as well as the spark as i have a light lit up on the dash which i think is the injector light or is that another problem,and asuming i get the car started should i continue to drive on the Red key or should i get a Blue key if so will i have to go to Fiat to get one

not use the red key for anything other than programming blue keys into the ecu. dont use it for driving or starting the engine.

once you have the ecu fitted you can use the red key to teach the code box any blue key codes. for this to work you need to have 2 blue keys with unique codes (different codes to each otehr and the red key)

how do you make these 2 new blue keys?
easy. you go to timpsons with your red key and any 2 blue keys from any fiats that uses the system1 immob (bravo brava marea cinqcento mk1punto)
tell the guy at tipsons to copy your red key twice, but dont copy the red key code, use the codes from 2 blue keys. then you'll have 2 copies of the red that each have unique codes.

now you have a set of 3 keys, you can use the red to programme the 2 blues into the ecu, then they will start the car. programming is a very easy 2 minute job, the procedure is in this thread, and in several other threads in the bravo/a section and marea section.

Right can I end this please!!!

You have red (master) key yes? And you want 2 blue (slave) keys yes?

OK here goes......

1)go to dealer/timpsons/woolworths/sunday market/asdas wherever you want to get 2 blue keys. I state dealer because alot of cheaper keys that you can get can sometimes have difficulty programming thats all not because i'm biased.
2)Get keys cut to same pattern as your red one.
3)Leave the shop/market/supermarket(delete as appropiate)
4)Try cut keys in car door to make sure they are cut correctly
5)Get in car
6)put red key in ignition & turn on,wait for code light to go out(about 3 secs)
7)take out red key & put one of the blue keys in,turn ignition on,wait for code light to go out(3 secs)
8)take key out & put other blue key in,turn ignition on,wait for code light to go out(3 secs)
9)take blue key out & put red key back in again,turn ignition on,wait for code light to go out(3 secs)
10)take red key out.
11)try both blue keys & make sure engine starts with them both.
12)put keys on key ring
13)drive home
14)switch on PC & access Fiat forum website
15)Donate £5.00 after all you have saved £££

The end

Dose this actully work?

If I got 2 new blue keys from ebay, had them cut and followed the above everything would be 100% a ok??

How can a "new" key already have a code on the chip???????

 

[Helz]

If you have a red key, yes.

All you need to know is here.

 

[madrat]

I will be keeping that bit of info in a very safe place. In the meantime I am going to get a copy cut and programed for £19 on the market, unless I can get a couple of new blanks for less than £19 off ebay.

Thanks for all your help.

yes it works, i've done it dozens of times.

if you have your red key then yes everything would be 100% ok if you bought 2 blue keys.

that last question is a bit crazy. how on earth could a new fiat key not have a code? if it didnt then where would the code come from and how would it get on the key? obviously all new fiat keys must come precoded, how else can an immob recognise them?

it is critical that your new blue keys have different codes to each other and to your red key. when you get a key cut at a locksmith's it is not precoded, they will need to copy the code form an existing key, you cant let them do that, you must provide a code from another key not from your car (any fiat code system1 key including bravo brava marea, mk1punto, cinq). if they copy the code from one of your exisintg keys then it will not be a new key, simply a clone of an exisint gkey, and in that case the programming procedure will fail because the immob sees them as the same key.

 

[madrat]

Ok I'm going for a cloned key for now.

Still strange to think a new key has a code, would have thought it would be blank and waiting to have your code from red key programed on it.

if you put the red key code on it then how would the immob be able to tell the keys apart? all 3 keys must have unique codes to each other, if any are the same then you can't program them into the immob.

I have one blue key and one red. The central locking and alarm don't work, I have replaced the battery on the blue key but still no joy. The light on the fob dosn't light up when the button is pressed.

I don't have a key card. Will fiat sell me new keys without the key card?

If I program the news keys as described in this thread will they work the central locking and alarm or just the immob? Do I need a key card to program central locking?

Is it possible to get a new card?

 

[jug]

The light on the fob dosn't light up when the button is pressed.

time to repair it, usually that involves resoldering the 4 contacts on the switch, easy 1 minute job.

which batteries did you use? there should be 2 of them, both CR2016 if i remember correctly.

 

[andyred]

I have done some more searching (I've been on here for hours) and it seems I need a code that came on a bit of paper with the keys to program central locking.

Is there any way around this such as repairing/replacing the faulty PCB in my blue key or some how cloning it? Is the only way buy a receiver and new key with matching code?

I have read that Fiat won't know the code, this is very poor service, other manufaturers can tell you all sorts of codes from the registration number alone.

Sorry missed your reply, It only had one CR2016 in it so I just put one in. I will get another.

if you have a mk1 then you should have 2 codes, both come on small paper keyrings, either of these codes is needed to reprogram the remotes. on mk2 model the codes are held on a database by fiat, i think you can pay for them, but i'm not 100% sure since i've never done it.

the codes wont help you fix your remote, plus you wont need to do any programming once you fix the remote, it should work.

 

[andyred]

I've got some more batteries coming in the post tomorrow. I will try them. It's good to know Fiat might have the codes, I think I have a MK2, it's from 2000 on a W. I can't find a CD changer wire so I think it's a MK2.

 

[bandido41]

Fiat didnt keep the mark 2 codes i tried to get them for mine but was told they didnt keep the codes from the mark2 onwards for security reasons.

 

[jug]

in that case you're buggered if you cant get your remote working because a year 2000 model is a mk2.
