Thank you very much for your praise, I can only calculate what the module ultimately costs once I have integrated all the functions.
Surely you could offer it like this but my goal is to replace the skreem completely, because with the original key fobs there are also delivery problems.
But I am not sure which way I will go, again with radio keys, with rfid tags or...

But anyway i need help from you find someone who can deliver the finished modules to you in the us and take over the service.

This person must meet the following requirements:

1. he must be known to you as reliable
2. he must have at least one Crossfire
3. he must be able to program the EEPROM of the PCM
4. he must take care of customs clearance

My goal is to make a collective order later, the person has to collect the money (the whole thing would only be possible by prepayment) and send my share to me.
Later he would get a package with all ordered modules from me and has to send them to you.

Of course he does not do this for free, I would then agree with him to set a total price for you where all costs like shipping, customs and support are included.

He must be able to program PCMs, for those where the skreem is already broken.
There I will deliver my module together with codes, so that he only has to program your PCM for these codes.
By programming I mean changing Code in the EEPROM on the PCM.
