Technical Key Jerryrigging

[koalar]

You got a link to a key from China, Koalar?

Can't find any locksmith near me who'll do it

I have Delphi, WoW and MultiECUscan. Need a new shell. There only a couple of quid. I could get a full remote and test


there at least three or four different types and I am not sure which is correct they look identical

Delphi/Marelli assume this is the type of body computer. Easy read by software
434MHZ This is correct the other frequency is for the USA
ID46 not sure
PCF7941 not sure
2 or three button, does it matter
here one of hundreds

I dont believe a remote thats already been programmed is easy to reprogramed or added to a different vehicle


virgin remotes as £10 from china



of cause as its not something I have tried I could be completely wrong

A used remote is just as easily matched to a car as a new one.

You just need the cars remote code (obtained from main dealer, shouldn’t be more than £15 plus VAT) and MES.

The immobiliser is a different kettle of fish though. Premium an auto locksmith can do that based on what others have mentioned and I’ve read elsewhere.

its a rolling code as far as I know once its lock to a car its done

There are many more similar threads on auto locksmith forums were everything fail with a s/h key but a new key works.

I have never really gone that far into it

The CODE is stored as plane text on the body computer a decent auto locksmith should be able to read it directly from the OBDII connector

Seen this done. Less than 5 minutes


Of cause I could be miles off as I have never tried myself.

It is a rolling code, but it’s still programmable.

I know as I’ve done it first hand when the remote on my Stilo fell out of sync. Obtained the remote and immobiliser code sheet from the main dealer and programmed it back in with MES

just checking

we are talking about adding key from a different car

not a new key

not a pre programmed from a dealer

or original key thats out of sync


because

"Obtained the remote and immobiliser code sheet from the main dealer"

is a piece of cake and a completely different kettle of fish to the original question.

How is a key that’s fallen out with the car and no longer recognised by it any different to using a used key from another car?

If it’s fallen out from the car then the car won’t know if it’s a new key or a used key.

The code sheet enabled you to resync the rolling code system.

There more going on. When you First program the key a few bytes are permanently written and can't be rewrite.

the only way people on the auto locksmiths have got it to work is to unsolder the chip and put a blank one in

if they are cleverer enough to do this and to read the CODE direct from the body computer I doubt they are wrong. I have a S/H key here and I can test if you like. But dozens of people have already tried and failed.


A few people say they have a solution. But I doubt they are genuine

from another forum

"Remotes are precoded for each car like the transponder is. In my experience only remotes supplied to vin will work. My other half used to have a 2005 Punto tried programming 40+ different remotes to it with no success only the original remotes would program. Used Fiat Examiner, AD100pro, AlfaOBD, SBB... never had any success."



If a new key might not be that straight forward

Moral of the story -

Any Fiat with just one key has CONSIDERABLY LESS VALUE to cover cost and hassle of getting a replacement key.

I mean i see what you mean but i don't agree. An incredibly slight hinderance to me unlocking the car doesn't give it 'CONSIDERABLY LESS VALUE'.

It's not a Jaguar E type.

The moral of the story is, cheap runabout cars are just that, cheap runabouts. I think I'll survive with one key.

It's a significant issue for younger cars. If I were buying a newish Fiat without the remote key, I'd pay £500 less than I would if both original keys were present.

The moral of the story is, cheap runabout cars are just that, cheap runabouts. I think I'll survive with one key.

I get that point too. If we're talking about cars worth under £1000, then paying close to half that for a properly coded OEM remote probably isn't justified. Just remember that if the worst happens, and you do somehow manage to lose the one remaining key, getting the car recovered and working again could cost you more than it's worth. However, there are third party locksmiths who will supply and code the car to accept an aftermarket non-remote working key and leave you with a reasonable amount of change out of £100, but you need one working key as a starting point - getting this done now will seem like worthwhile insurance if you ever do lose it.

At least we've moved on from the Fiat type 1 system with the red master key. Lose that, and you had to change the complete lockset & immobiliser; even back in the day, you wouldn't have seen much, if any, change out of £1000.

And here's a recent thread form someone with only one key, which is now lost. https://www.fiatforum.com/newbie-central/486560-lost-van-keys.html

 

[DaveMcT]

Nobody wants a car they can't use so the loss of one key chops the value of any 169 Panda by at least £200.

If you know someone with zedbull full its quite easy to read the PIN CODE and precode a virgin key and then program it to the vehicle. Although once precoded most software will add it.


It is possible to reuse a secondhand key but it not as easy and quite involved.
