[thomas12]

Hello,
can someone explain me how can i prepare a used key for another car.
I bought a used key ,now i want use it for my car.
So i open the key and ther is a epcos transponder coil.
It is possible to unlock this transponder?Or need a new?
Which is the right transponder for the Polo 6r 2011?
Thank for your help

Break of the old transponder antenna coil, and replaced it with a glass id48.
Then programmed it.

Ok,thanks
The glass id48 solution is a good idea.
But i want to replace the old epcos transponder coil with a new transponder coil?
The old transponder ist a 502344A000,do you think this one
http://www.mouser.de/ProductDetail/EPCOS-TDK/B82450A2364A000/?qs=dEfas%2FXlABIrFyGQ9BcvoQ%3D%3D is the same?
Can this one also programmed,like a id48?

I do not know this, i Always put in a new id48. cheapest, and fastest. never failed me yet.
But go ahead and try the epcos way.
Keep us posted.

You have to replace 1 and 2 on picture if you want to have like original key. But #2 has same data for key ID and remote which you have to write to new chip ( I think no one can do that). #1 is just antenna coil that transfer info form #2. Or if you can Unlock #2 you hit Jackpot :biggrin:.

Just disolder #1 and put glass ID48 like Rod h mention.

Ok, i understand but should the circuit be closed with a 25 ohm resistor?
Do you know which component is #2(red sign) ?
Atmega?Or ?
359254

No fancy resistor is needed!

m8, you just wasting your time.
Simply Disolder antenna coil, put glass ID48 chip at same place, glue it and you are done.

Ok, I will do that
