HELP, MITSUBISHI GRANDIS IMMO RESET, can not program key

**nja** · 25th April, 2017, 10:47 AM

hi guys, I have a mitsubishi grandis, I wanted to program a new key but I did a reset for IMMO ECU, now the system can not program any key, do I need to write anything to engine ECU? IMMO dump attached.

I tried password 4135 and 0000, doesn't work.

thanks. already tried many time, didn't work. the data in immo seems damaged, Is there any way to rebuild? I also tried burn the bin file from other car but still no luck. in the data flow it shows 0 key.

Thanks again. I read some information from internet, it seems I need to register immo ECU first then the keys, I think after the immo ECU rest some data are gone, like chassis number. there is another password to register the immo ECU which is related to the serial number. my situation is like replacing a new immo ECU now. but I'm stuck now.

I'm stuck with a grandis, is it all you need to do is write a good dump and leave ignition on for one hour? car is far away plus taking a ferry, 2.5 hours each way, does anyone have a good solution for my problem? Did a immo reset which blank the immo, wrote new immo dump and there is no sync, no dtc, remove transponder and comes with dtc for transponder. there is no spark after. will not accept 4135 or 0000 to reprogram key.

thanks
