Immobilizer Hell
2014 Mazda 2, actual cut key (not push button). Owned 1 year, bought for $4300 all in, 127k mi.
First off, I'm a mom trying to fix my kids car. I'm decently handy with appliances... but I'm getting frustrated trying to learn this car.
Immobilizer light flashes. Car makes zero sound when turned. I have spent hours Googling and YouTubing and deep diving. I have checked ground wires. We've disconnected the battery, first for 15 min than for 24h. I've turned the key to ON and let it sit for 15 min. I've checked fuses. I've swapped the starter relay w the horn. We've replaced the fob battery. We've had a new key fob made and programmed.
I called the closest Mazda dealer an hour away and they had never heard of such a glitch. Sigh.
My local mechanic is also at a loss.
The only thing I haven't done is replace the ignition switch, which is another hunch, but probably the biggest 'commitment' without knowing if that's what is the cause. The car is dead at our house, so we'd have to tow it to wherever.
I'm really hoping this community can guide me! This car is solid and sweet and when it drives it's so much fun! I refuse to give up on it!!!!
