just getting back to an earlier question in this thread, that of swapping the chip from an old style key to a chrome key. wardpaa has tried this and it did not work for him. the locking functions were ok but the key was not accepted by the eis for drive authorisation. he concluded that the second chip, which was a different size on the two keys, was used for the DAS function. as this second chip could not be swapped he put the main chip back in the original key which still worked ok. hth

I remember that now,,though a chip can look the same, the pin outs could be very different

 

[Alex Crow]

indeed. i notice that available on ebay are an eis explorer, which shows various codes and such, and a key programmer - both from the same seller! not in china oddly, but the land of the cloggies. i wonder if these two items cold be utilised to save mercedes owners many thousands, or possibly help the criminally minded!

her you go...

as they are not copies of MB products, and are available on a respected and well known internet site, i am sure this post does not fall foul of forum rules. if however it does, may i request that only this post be penalised, not the entire thread

I cant see the programming as being viabl, you need a key to start with, and most secondhand ones have faults other than the chip

are you talking about the ebay ones malc? i am rather intrigued by that ezs decoder, tempted to put a bid in...

 

[television]

Yes I am My next thing is to pick up the dud EIS switch that I saw in SAMs place,, the one that I have is too far gone. Then fix up a test bed for when I start winding the new coils,, I could even do it for the dealers

 

[wardpaa]

What exactly will the EZS do for you Alex ? Does it work with the AK400 ?
I saw the AK400 in action on youtube and it looked pretty slick.
Was interested in this stuff when i was playing with the chrome key but the 'investment' looked too dodgy with sellers being abroad, ebay sellers etc.

 

[television]

Is it worth while messing around to that extent,,I find it bad enough fixing other problems on the keys

 

[wardpaa]

True malc. You would have to be pretty die hard to invest £500 in a product that is not totally familiar, and has no support etc. You might get your money back eventually and as you may know if you have fixed things for people in the past, carries a lifetime warranty to boot.
If you fix someones key and their wheel drops off the next day; its your fault !

I though that the repaired keys caused punctures, thank you

just watched the ak400 on you tube, it seems the ak400 claims to be able to re flash existing chips! so a question to malc and paul, is it possible to re flash the chips mentioned on the ak400 demo? i assume so otherwise the claims would not be taken very seriously! also, if this is possible and the ak400 does what it says on the tin, your money will buy you a machine to program a car to any key you like! legitimate purposes would be to reprogram a s/h ecu or eis to repair your car for less, illegitimate uses might include all sorts - although this machine will not let you steal a car without desoldering chips from several modules which would be a good days work all in!!

for my part, although this subject fascinates me i just do not have the time or 'brain space' to get deeply involved! incidentally the fact that the demo shows the reading of a key and the flashing of the 3x chips on the car strongly suggests that recoding a key is not possible with the ak400. that is very believable, and goes with what you might expect from a good key security system - IS it possible to produce a chip that cannot be re flashed then? i guess so...

 

[television]

Reading the blurb on EIS some time back,,they are write once only. On the one that I looked at a while back they sold the blank chips

Yes it is possible to make chips that cannot be reflashed

I am sorry, that is too expensive for me to play with as I would have to do it by hand. Though I am a little out of touch now, there are some electronic firms who have the jigs for doing this.

For anyone wanting to have a go by hand.

You clip the legs on the chip that is not needed on the chrome key, lift the chip then just with a de solder gun, suck up the ends of the legs..

To get the good chip off the old board, you just go round the chip with a soldering iron, lifting the legs as you go and remove it. then straighten the legs.

You need some glue to hold the chip in the correct place, with all legs aligned. then flood the legs with solder down both sides. And last you just use a desoldering gun to remove the solder from between the legs and job done

No problem,
Ill keep looking.

With the answer from wardpaa it seem as though it would not,or does not work
