new transponder/Immobiliser PCF7935DS chip
« on: July 16, 2020, 08:36:59 PM »
I have read
https://www.fordmpv.com/smf2/ford-galaxy-common-faults-and-problems/ford-galaxy-immobiliser-key-programming-and-information-(mk2)/msg7389/#msg7389

Very clear !!

My remote on remote key (key A in piece above) is not working any more. Bummer So I bought a new key here for my ford galaxy 2003 2.4 lieter automatic.
https://www.aliexpress.com/item/32865959375.html?spm=a2g0s.9042311.0.0.1b4c4c4dAafC9B [nofollow]
For €17,54 and arrived in two weeks to the Netherlands. Excelent.

Programmed the remote in one go. Great I can lock and unlock the car. Great. Works fine. Got it cut localy. Eugh cost me €17 :-(
But there is no transponder or Immobiliser chip in this key to start the engine. Never mind I took out the chip from key A (as the remote wasn't working anyway). There is a special slot to put it in. Car starts no worries. Great. 

Now comes the question. I want to buy a few more of these keys. But I will need to buy the transponder/Immobiliser separately.
I saw that is the PCF7935DS (there are some more codes VA9TC6 07  and 03111)

The problem is I can only find PCF7935AA and PCF7935AS .
Are these the same? As anybody tried?

I have all three original keys so I can "program" the new transponder/Immobiliser according to the above document.
Any help is appriciated

Louis

Hello and welcome, our continental friend! Greetings from England! The Netherlands are very nice and in many ways our closest neighbour!

Now then. Truth be known, it’s not worth faffing about with making your own keys. By the time you’ve bought the parts, had the key laser cut and wasted hours trying to program the thing in without locking yourself out your car, you might as well have just spent an extra 20 quid and gotten it done at Timpsons or somewhere like that. My suggestion is to find a friendly local locksmith and just ask them to make them up for you. They will probably do you a discount if you buy several.

I drive a Seat Alhambra 1.9Tdi which has 115bhp and an automatic gearbox.

I am happy to help you with all your questions. I am not a qualified mechanic but seem to be better at fixing my car than even the most experienced garages.

I have lots of friends here and very much enjoy talking with you all.

Always remember, a motor car is a serious tool and should be treated with respect. Put your safety first, always.

I've brought the blank transponder chips from auto wave on ebay previously, you need them precoded a blank one doesn't work I gather.

Note these will only work for the Ford models, not the Seat or VW models

https://www.ebay.co.uk/itm/NEW-Ford-Galaxy-2000-2006-ID44-T15-PCF7935-NXP-Transponder-Chip-UK-SUPPLY/122870799935

I've used for forscan to add those chips to a 2001 with only a single key. https://forscan.org/ I think I was also able to program a 3rd key with 2 working ones, by using them one after the other then using the blank. Forscan will let you remove the lost ones though. You just need a compatible lead which was around £20.

Not sure if autowave will post to you, but worth asking.

Locksmith would probably want at least £30 a chip to do them, so it's worth doing yourself. The one I asked to do it spent an hour messing around and then proclaimed it to be impossible to sort.

Thanks for the hint SirDavidAlhambra, but with a remote the price difference is significantly more. I paid around €34,- (plus the transponder1-2 Euro) against a remote (not cut and not programmed) around €160,-
Anyway where is youre sence of adventure???

I will have a check what mine is in next couple of days, , haven't got my keys with me at the moment. but note what was said about precoding,  you need that done for it to work as well. The one I linked to will be precoded. Otherwise you need the kit to precode it as well. I got the impression that want particularly expensive to obtain though wasn't worth me looking into it for a couple of keys when the precoded ones were available.

One of them (a spare chip that isn't in a key but is programmed to the car) is PCF7935AA
This is one brought from Autowave mentioned above, and was sold as precoded for use on a Galaxy.

It may be easier unless you can confirm they are precoded, to verify with the seller that they are really precoded.

Supposedly (I have not tried this!!) but this kind of device can do the precoding
https://www.ebay.co.uk/itm/Smart-Zed-Bull-Transponder-Cloning-Programmer-With-Mini-Type-No-Need-Tokens/333652873017

Allowing you to use the cheaper blank chips (same type as above, but not precoded). But for a couple of chips as a one off, its cheaper to just buy the precoded chips.

Hi guys,
I promised to give an update when I had finished with the key project. I have and thanks to Bo Christensen !! He give me the crucial tips during my adventure. For an adventure it is.  I heard on this form that the keys are quite cheap in the UK. Unless you want a challenge don’t do it. In the Netherlands the cheapest key I could find with programming (not cut yet) was over €80,- (ex vat 21%). Keys with a remote were over the €100,- If you are not into computers it will be a real challenge.

There are several parts that need to be understood before we go on. There is a blade, the transponder and sometimes the remote.  The blade and transponder are necessary to start the car, and the remote (or the blade) can be used to open the car. The remote has nothing to do with starting the car and the transponder has nothing to do with opening the car.

The transponder must be “prepared” before it can be programmed. This “preparing” can only be done by a programmer like the mini ZenBull.  A clone can be bought quite cheaply. But beware, I had a terrible time getting the software to work!! I will put an account below.  If you don’t have an old XP or Windows 7 computer you will have troubles getting it to work. Everything I explain here I got from different place on the internet and from Bo. There is no original work by myself.

The steps are quite simple.
1)   Prepare the transponder. I used the Mini ZedBull. The steps are

a.   Put the key with the new unprepared transponder chip in the programmer
b.   Zedbull 5.08                         (start the program)
c.   Transponder Production           (select this. In upper right corner if I remember)
d.   44 VAG                                (select this)
e.   Sharan 2000                         (select this)
f.   Produce Transponder              (press/select this to program "prepare" the chip)

You will get a message “Transponder production is successful” on the PC.

I programmed 5 keys on key #1 and all worked. I don’t know why there are more “keys” . You can not clone the transponder. Don’t ask me why. It is a given.


2)   Now for the programming of the key/transponder. The following steps need to be carried out within about 5 seconds of each other. Have the two original keys and the new key ready.

a.   Put original Key 1 into the ignition and turn to Position 2 (Ignition On or the one before start)
b.   Wait 1 second and then turn off and remove
c.   Put original Key 2 into the ignition and turn to Position
d.   Wait 1 second and then turn off and remove
e.   Put the new key into the ignition and turn to Position
f.   Wait 2 seconds and then turn off and remove

I waited in position 2 till all the “startup” lights are off (last light was airbag) then I turned it back and removed the key.
The car should start with the new transponder.


3)   Remote key programming instructions for the Ford Galaxy with key 5WK4 790/97/98 . Now for the remote to get in the car. Remember, you need to program ALL remotes together!!

a.        Ensure all doors and windows on the vehicle are shut
b.   Insert key into driver’s door lock.
c.   Turn the key to the unlock position 3 times and keep the key in the lock opening position for 5 sec.
d.   Remove the key.

The driver’s door LED will illuminate. Within 20 seconds:

e.   Press and hold the lock button.
f.   Still pressing the lock button - press the unlock button 3 times.
g.   Release the lock button.

The driver’s door LED should flash to indicate correct programming.

h.   Repeat steps  e to g for additional remotes up to a maximum of four.
Wait 15 seconds before trying remote.

I bought the transponders on aliexpress. They should be PCF7935 chips. My were from NXP PCF7935AA. The original one in the car was an PCF7935DS. I also saw some PCF7935AS. I believe the transponders should be PCF7935 with an ID44 https://www.aliexpress.com/item/32919374038.html?spm=a2g0s.9042311.0.0.11de4c4d5k2Y8w [nofollow]

The remote key I bought also on aliexpress.

This is without the transponder and the blade needs to cut.

This is where I bought my Mini ZedBull. https://www.aliexpress.com/item/1216017853.html?spm=a2g0s.9042311.0.0.6a974c4dVc6yHC [nofollow]
It came with an US plug on the adapter. No EU conversion plug. They recommend to install the software on windows 7. It needs dotnet framework 3.5 (not lower , not higher) and you need to install their USB to serial drivers.

I had a very very hard time getting the program to run on the computer. On my windows 7 machine I had dotnet framework 3.5.1 and using that just crashed the program all the time. It refused to downgrade to dotnet framework 3.5  I tried an XP where the dotnet framework did install but it refused the usb drivers :-( . With windows 10 it complete crashed. In the end I reinstalled windows 7 with no internet to prevent an upgrade and got it working (second reinstallment attempt). Then the hassel with the usb port drivers. Suddenly it worked. But then the computer would connect but could not communicate. Changed the serial settings to 115200 baud, 8 databits, no parity, 1 stop bit, flow control Xon/Xoff. 

Then all worked. Pffffffff

Again I would like to thank Bo Christensen and all other who helped.

Louis

Good work,a thorough write up there. The precoded chips would already be id44 type for future reference, but good to know the zedbull works to sort that step out.
