As far as the present no start condition, re-check that after you are sure the battery is fully charged. With a fully charged battery, if the starter motor does not run that signifies an electrical problem in the starter circuit or a problem with the starter motor itself. If there is power to the starter motor and yet it doesn’t run, the starter is condemned and replaced. Alternatively, if there is no power to the starter, or there is a big voltage drop anywhere on the circuit to the starter, then the circuit has to be traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. Regardless of what the underlying cause of the no start condition is, if you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you.

Other than an immobilizer unit the trouble could be caused by a faulty ignition switch or ignition relay. The Ignition switch and relay are critical components for sending the signal to turn the vehicle on and off. Your vehicle is presenting signs of a security lock out. Common causes of security lockouts with Honda and Acura are a bad battery or poor connections leading to the battery. I suggest that a technician test the ignition switch key reader, ignition relay, the battery, and its related connections.

Improper alignment or installation of the starter can cause this grinding noise to occur. However, it’s also possible that internal components inside the starter, the starter relay or the flywheel teeth could also be the source. It’s really difficult to diagnose a noise without physically being there to inspect the vehicle on site, so you should have a mobile mechanic complete a car is making a noise inspection, so they can pinpoint the issue and recommend the right repairs.
It sounds like you may have a faulty starter solenoid that may be dragging a bit too long against the flywheel after the motor fires. This will cause the starter gear to engage the flywheel once the motor is running at a much faster pace than what the starter gear is turning at. The result is a grinding sound causing the starter gear to drag against the flywheel, eventually burning up the starter motor. I would suggest double checking the power to the solenoid to be sure it retracts when the key is moved form the start position back to the run position.
