Hi,
I'm hoping someone can help. I cant get a 2003 corolla to pick up a transponder signal. I've tried virgin dumps, the car goes into programming mode as it should once a key is inserted but then the security light flashes the error code after being solid for a few seconds. I've tried dumps with existing key data and generating keys with no luck either. I've tested the ignition ariel with a key tool and its picking up a signal, so its looking for the key. I'm out of ideas... Unfortunately, the original file was corrupted. Would anyone have an IMMO OFF for me to try? the original file and two other dumps are attached.
Any advice welcome, thanks.

What tool are you reading the 93c56 with and what mode ? Read 93C56 under 8bit mode and write your transponder in 16bit mode is the formula.
