I just put my car key into the ignition and it came up showing the green immobilizer key indicator light and the battery and low pressure indicator lights, after retrying it for a 3rd time the green immobilizer light just flickers and goes off. A 4th and 5th attempt did not even start the ignition anymore and my car can't move. What do I do to get the car back working?

Try removing and fully charging or replacing the battery. Most auto parts stores will test and charge batteries for free. If it ends up truly being an immobilizer problem, you will likely have to take it to the dealer.

Thank you very much for your advice, I have finally changed the battery with a fully charged Honda battery and the car now starts and works perfectly. I have just given it a test drive and all the warning lights are totally off.
I had called the honda dealership earlier in the day and was told that I need to get a towing vehicle to bring it in for a new recoding of the keys and a potential $300 bill, you have just saved me that much without moving the vehicle an inch.

Nice job. That's music to my ears. Here are some tips to keep your Civic away from the dealer for a long time:
