Need help programming key for 2006 Astra H.

[super jumbe]

Transponder Phillips crypto ID46
Astra H can not programme transponder keep saying write with virgin chip any idea? I tried using opcom and x100+ and will not programme keys.
What?s the solution, thanks in advance?

Needs to be a remote key. You can't program a normal pcf7936.

It is a remote key id46.

[stalonerambo]

you need pre coded a pfc7936 with remote key,

Thanks mate how do I precode this chip, any were I can buy one...
Thanks again appreciate your help.

i program these with avdi or opcom. I dont precode them or anything, they come from my supplier & just program straight in. Its from a local supplier, Ive never been able to find a cheap chinese version

[Faraday]

you need pre coded a pfc7936 with remote key, on Astra H? this is pcf7941.

Have you read key(virgin) with some external programmer? I did it once with zedbull and f... key.
If you can't program try to delete keys and add first new then old keys.

I have bad experience with X100+ and OPEL, it deleted keys on ASTRA G but I could not program them back had to use tech2, also op-com doesn't work 100%

[cqae]

opcom has worked 100% for me, but sometimes if all key spaces are used, they need to be deleted first. I actually just did one 5 minutes ago & the original key was a pcf7941.

I usually use avdi to do keys though because opcom doesnt get the pin. avdi has never failed me on these and is pretty simple to use, I never precode anything, just learn in a new key & it works

[super jumbe]

I checked it is pcf7941 tried deleting all keys still an issue, keep nagging use virgin key. I am going to get new keys this morning and will keep you updated.

[estate]

reading these damages them.

[Bllinda]

I advise you to do it with Tech2.
You will save a lot of time. With E.f.fi make precode 4.3.3 and you try to program the key.
Only I do not have experience or operate central lock.

i have made same work on vectra (pcf7946 3buttons key)
vaux-com & op-com can program (pre-coded pcf with zedbull) direct on car,Can't program already programming pcf.
tech2 Can program used key (via can bus adapter)
i make key with new pcf and car start but still not work remote :D

2nd hand keys wont code in , it must be a new remote key unless you cahnge the chips on it and precode them , also as has been said if reading a new virgin remote key in a cloner/reader it often corrupts these so unusable.

[ihlocky]

Hi all in my neck of the woods we have 2 types Valeo and Siemens. ..they look identical but can't be used on wrong vehicle type ...i have used both dealer key and aftermarket and have never had a problem on either astra j or corsa d ...as others have said maybe key is damaged or wrong type of key was supplied ...regards Irvine

[ihlocky]

Correction read as astra h regards Irvine

It is possible to renew 2nd hand remotes by resteting(flashing) pcf7941.

and who has got the firmware to flash the pcf7941 ??

Also I dont know how reading these is meant to corrupt them - This must be a problem with the reader etc and must work ok with a decent reader else how on earth does the car read the key when its programmed without corrupting it?

[cqae]

can definately be read. Ive read them with my TRS5000 and cloned them with it.....

Buy, read f... key then you will see. This is from my experience, if you don't believe, try it.

[rapidlocksmiths]

it doesnt corrupt a programmed and locked key , so these can be read and cloned with jma , silca cloners etc , the problem is when a virgin non programmed key is read in a cloner , afterwards it will not always code to a car , 3d group as well as others sent out a warning on this some time ago and many people have fallen foul of this to date.

I mean it must be a fault with the reader, before the key is programmed the car has to read the key to get the data to program the key

World First Reset PCF7941 with Orange-5 ImmoHPX 4V0
Could this solution work?
If reading a blank key and then it got corrupted.

As far as I know this is for chrysler keys

so what are you using to read the firmware from a pcf7941?

[RFRemotes]

And what programmer to write it to "empty" pcf7941 ???
:)

[ninja123]

fresh car keys are listing this key as one they can unlock.

I would love to unlock these, I know its an algo of the pincode or a locked key would never be able to program to a new cim.

just dont know the rest :(

can't be fault with readers cos they all do it

Suggest its a "protection" feature of the chip to corrupt contents - activated when a reader accesses blocked sections.
(a guess cos no datasheet in front of me :))

[ninja123]

The data corruption occurs when trying to read all pages, not just reading in coil to see whats inside, this is safe to do.

[mikajna]

Mate in Codecard.lt you have prepared pcf7941, buy new transponder and swap with faulty...you will solve your problem. If your remote key is manufactured by Valeo.

not worth it at their prices!

[insomnia2009]

got one only recently from 3d group just coded straight in didnt have to precode , at first i was trying to put just transponder key but wouldnt work but i can confirm the ones from 3d group just code straight in

Virginised CIM receives ISK keys from body module via CAN, there is no algo PIN<->ISK in CIM module.
If some algo exists it is either in BCM or is calculated in factory then ISKs are put in new BCMs.

Well if you change the BCM and CIM and program the new ones with the pin code can you reuse the old keys?

If you can reuse the keys then the algo must be in one of them, if you can't then probably preloaded in BCM

[RFRemotes]

Yes, exactly. With such test it will become clear if they are preloaded or calculated by BCM from PIN. I only know that there is no algo in CIM so mystery stays in BCM.
