Unlocking Chrylser FOBS........................

[mojomojo]

Can a new transponder be soldered to replace an old one on a USED FOB? Thought it will work... seems theoretically right since its the transponder that locks up. Right?

On the rhk they have different remote data to make the keys only work on 1 or 2 cars, the asians have like a super chip type one for normal other for 6 buttons. Have them dumped but since only nxp are what I have been able to get only 6 buttons been working. Buy a super key tool and read out the eeprom and put in the key programmed to it and you will find where and how it is stored. Then you can read a brand new one and use that to read out the new keys info/crypto code. Read with a hightag reader and you have key and remote info. Or I could just post it but its been a trade secret. If your smart you can find it and generate virgin remote pcf7941 and then figure the fobiks. (a virgin dump and a virgin key put in the super key tool will give you the info to read the virgins and get remote data older works better ie skim dump.
