2012 I-Miev. Long story, but sat in storage most of 2019 after purchasing it in late 2018. Somehow misplaced key during that period; had to have one re-cut (from a dealership blank purchased on eBay); new key worked fine, but 12V battery was extremely low, per dealer & after it spent a while at dealer before pickup, it wouldn’t start without a “jump” from a boltpower battery booster.
Was planning to use a trickle charger on the 12V, but eventually found that Walmart had the battery for $110 total installed rather than the $300+ Mitsu was going to charge. With the new 12V in, the i-Miev will not turn over to “Ready,” even though the accessories powered by the 12V now seem to work great. Tried jumping with the Boltpowerbox, didn’t seem to do anything as the 12V is fine anyway.
From reading other posts where there’s been this combo of issues (no Ready, and yellow car icon with “!”), I’ve seen the RFID in the key being possible issue in one case, an issue with shifting into park in another, an immobilizer issue, and 1-2 other technically complex issues I don’t entirely understand.
I guess my question is, should I just throw up my hands and have the vehicle towed back over to the Mitsu folks? I kept expecting one of the turns to finally get the car to Ready, as the key physically turns fine...but no luck. Not really sure what else I should be trying, other than to possibly see if by some small miracle I can find the original key I had.
Thanks if you all have any suggestions...
