IMMO Sagem with with 93c46, Key 7935 + Remote Control, Old RENAULT MASTER 2001

[Sansanyc]

Hi members,


i need help with programm EEprom chip 93c46 from Sagem Immobiliser 8200032776H 11011030-8A.


Renault Master 2001-2002. I have one working key 7935 without remote, ID33 30F8F103FF7FE0000000C78FE3387E00. This key exist in Immo EEprom and active (now in e2p active only one key). Also i have 7935 key with remote control from another Renault Master: ID33 3000F01F077EE0000E00C771FCC08103. This key i want add to EEprom. Some solution?


EEprom data i was read with Carprog programmer after desoldering from IMMO Box. Autel, SVDI cannot read eeprom via OBD. Exist programm for read/write IMMO Eeprom without desoldering or any another way to programm new key with remote withouth desoldering?


Thanks for advice.

It is impossible to program a donor key together with the original one. You can program a donor key with remote control and make a copy of the transponder. But programming the used key is a complicated procedure and requires brain work than the presence of superdevices.

I not need to reprogramm chip U9280M in donor key. I need only add to IMMO EEprom data ID from donor key: 3000F01F077EE0000E00C771FCC08103. EEprom data is too small:

1d 24 ff ff ff ff a9 90 ad 9f 9f a9 fa ad b4 48
d7 ff 0f 92 dd 0f 9f 36 ad 00 00 1a 00 00 d8 24
00 00 27 03 11 76 10 01 08 30 06 41 23 02 ff 02
ff ff ff ff ff ff ff ff ff ff ff ff ff ff 16 fd
1d 24 ff ff ff ff a9 90 ad 9f 9f a9 fa ad b4 48
d7 ff 0f 92 dd 0f 9f 36 ad 00 00 1a 00 00 d8 24
00 00 27 03 11 76 10 01 08 30 06 41 23 02 ff 02
ff ff ff ff ff ff ff ff ff ff ff ff ff ff 16 fd



I think someone can decode this data for edit/add key information. As i know in this data also coded PIN information and ID from working key: 30F8F103FF7FE0000000C78FE3387E00. Autel and other can decode from this data ID existing key. But i need revese process, write another ID 3000F01F077EE0000E00C771FCC08103 to this data.

Thanks.

I perfectly understand what you need. You didn't read my post carefully. I can recalculate the ID into immodata a little later.

Thanks a lot.

it is not possible to add a key from another car and make the old original key work
such possibility does not exist without refreshing the key and the key cannot be refreshed
