Honda_Immo blocked after use Red key!

[rabee7878]

Hello for all,
--------------------------------------------------------------------------------------
Information of car:

Honda Civic , 1996 , it has 1 red key and 1 black key
----------------------------------------------------------------------------------------
Problem:

The owner use the red key to start the car, since it was inserted in the car ( by a mistake ) and the car does not start.
Only showed a flashing green key on dash, but when used black key again the green flash goes off, and also the car does not start
--------------------------------------------------------------------------------------

I read EEPROM (93C46) and i program new transponder chip but the same problem still appear (the car wont's start)

Please what the correct procedure for programming the the black keys again?

-------------------------------------------------------------------------------------------
My tools for programming keys
1-T-300
2-SBB
4-Tango

Note: I don't find where the OBD location for HONDA Civic 1996.
---------------------------------------------------------------------------------------------
regards

The dump of EEPROM (93C46)

You must have another problem friend, I suggest you set the scanner and can scan your system.

Ur red key may have some problem or red key data is erased in imm so when u insert the red key green light is flashing so if ur green light goes off with black key means imm is normal scan the car u have have other prlm.

Thanka a lot for help, i don't find where the OBD location for HONDA Civic 1996 to scan it.

By using the red key to start the car it has scrambled the data on the immobiliser. You may be able to get a replacement immobiliser. Read the eeprom on the new immobiliser and post the data here. Someone will be able to give you the data from it to write onto a new transponder to make a red key. Use this transponder to manually add the keys you have. Do not try to start the vehicle with the red key.

You will not find an OBDII connector for this vehicle, you have to look for is an old Honda connector 3-pin.

Look in the passenger side if right hand drive up near the centre consul.

Read and fill with FF eeprom from engine control unit. This mean - you lost synchro between immo box and ecu. When you fill ecu eeprom with FF, ecu will automatically synchro with immo box.

Hello fellow DK.

I liked this information, never happened to me and I'll remember for next.

I have a question for you, as the synchronization is done or how we do it. I do not understand this
if reset the (44pins OKI processor and M851G EEPROM) as a 93C46 all to FF FF is synchronized with this alone?

[bugajewski_pl]

Read M851G as 93C46 eeprom. Fill all memory area with "FF" bytes. In this theory ecu will synchronize with immo after first ignition switch with valid key.

The problem is solved by save FFFFF- in EEPROM, 100% working, Thanks for all ,,,
