Question about 2004 Honda Accord
I tried making a new duplicate for my car key, i discovered the ecu would only accept one key even after repeatedly programing it with my t code programmer. it stores one and wont reconise the other. its my ECU faulty, or do i require any thing.
Some ECU's will only allow a set maximum number of keys to be coded to them. You may need to erase all the key codes from the memory and start again from scratch. Not sure if your t code programmer will do that, not something I'm familiar with, but it may need to go to a Honda dealer for erase and recode. Not something that should take very long or be expensive. Some locksmiths do car key programming now as well and often cheaper than dealer prices, you could try around some in your area.
