You'll have to pay attention to that key light when the car will not start. If the key light behaves normal, then you may have a different issue.
When the car doesn't start, what happens when you turn the key? Does the starter crank the engine, or does nothing happen?

It is not the sound of the chip not being recognized, I know all about that. Once in awhile I used to lose the chip out of the broken fob. Same chip though still.
The sound reminds me sort of a dead battery - nothing happens, but the panel is lit up. A slight sound then nothing happens. Gas pedal to the floor. When this occurs the key is lit up as well as the Maintenence Required sign next to it and everything else is lit up.
Took the car to work today. On my lunch break and again just now as Im leaving, the car did not start.
I locked the car door with the key while inside the car and it started. Right away just now, earlier today it took a couple of tries doing different things with the locks while in the car from the key fob.
I feel like the problem has something to do with the locks and maybe the drivers dome light(?)
Im afraid no one is gonna know how to fix this. Places are gonna charge me to repair something bigger than what I need.
Thanks for your input I greatly appreciate it.
I don't know if I am ever gonna be able to show up at work or not.

Doing as much diagnostic work as possible before taking it to a shop will probably save you money in the long term. I'd recommend recording the gauge on you phone when you get into your car. Turn the key to the II position and wait for the check engine light to turn off. Then try to start the car. Hopefully you will get a video of a good and bad startup to compare. You can upload videos to a youtube account and post a link on here. We may be able to diagnose.
You may not know the answer, but does your car have an aftermarket alarm/remote start system? You can look under the driver's dash and look for wires out of place leading to a box. Most wires under the dash should be fairly organized. If you see rouge wires that are spliced, etc. you may have an aftermarket system installed. You can take some pictures under there and post them on here.
Other items it could be is an immobilizer issue like discussed before, a faulty electrical portion of the ignition switch, a bad starter. These are all things you can diagnose or you have to pay someone to diagnose. I know car work is expensive, but you may want to find a good independent shop. Based on your user name, I'm guessing you live in NJ. There is a youtube channel called New Level Auto. He is based out of NYC. He may know of a good shop in your area for diagnostic work. You can probably send him a message through youtube.

Check engine light is always on. I got bad codes for the catalytic converters 2 yrs ago when I went thru inspection. A mechanic reset the car somehow and I was able to have the light off and got thru inspection. There was no repair of the catalytic converters so the light came back on soon after. Inspection in NJ is all about emissions and I think I heard it's the same standard as CA.
Those are the receipts from the tests I had done at Auto Zone.
There is no remote starter in this car and no aftermarket alarm that I know of. It was my understanding he only had the ignition replaced and a new key, which I dont think was ever programmed to the locks. I had to get that done.
I am wondering if I disabled the alarm or something(?) The red light is flashing but if I am inside the car and lock the locks with the remote and then manually unlock the drivers side door and open the door, shouldnt the alarm go off? It doesn't.
Sometime before all of this started (I believe) I didnt have the key fob taped up and the cover was loose and I accidently hit the panic alarm and various different locks several times over the course of a few days.
I have to wonder why doing things to the locks sometimes gets the car to start.
I will contact the place in NY.
Thanks again

Hi I found this forum, know very little about cars so bear with me. But, I could use some advice from those of you who know about this kind of stuff.
The whole story:
I inherited my dad's 2004 Honda Accord EX Automatic (I think it's v6 but I'm not sure, sorry) 138,000 miles on it at this point.
I believe he had the ignition replaced because the key for the ignition doesn't go into the door or any other locks and all I can really do with the key is lock and unlock the doors and start the car. I'm okay with that. I pop the trunk from inside the car. I understand replacing all the locks and new keys is expensive.
I have had the current key fob fixed a few times. I always had the chip and the metal stick part and a locksmith would put it into a new case, $75. Within a matter of months the key would break again so I just tape it shut or deal with it in pieces (This last time he glued the chip into the key with some kind of foam. It was fine for the last 6 months).
Now there seems to be an immobilizer or key problem. Sometimes I can't start the car and the green key is blinking when I take the key out. Sometimes then, I lock the doors while Im inside (with the key fob) and I can start the car. Sometimes I can start the car if I do that thing where I go from 0 to 2 back to 0, remove key, go back to 2. Sometimes that doesn't work. Maybe Im pressing the key in too much or not enough. Then I unlock the car or lock it again or do any number of things and it starts.
I ( lightly) popped the gas door with a screwdriver when it was frozen shut and the door isn't always closed. AutoZone tested the car and the report said loose gas cap. One day I got out and clicked the gas cap 3 times and then was able to start the car. Coincidence? I don't know.
Auto Zone suggested replacing the battery in the key fob and then amazingly the car starts! But not necessarily the next day or the next time without some trouble and trying.
I can't help but feel that this started sometime after I started accidently pressing buttons on the key fob. It was broken as it almost always is, and I was accidently hitting the panic button, etc. I'm wondering if I did something wrong or mis-set something.
It seems so much like it has to do with the key fob in some way or another.
Took it to a Honda dealer hoping to have it reprogrammed. I have reason to believe it was not properly diagnosed according to Honda protocols on the Honda diagnoser machine. Mechanic was just casually diagnosing the situation.
Receipt says: Technician found the immobilizer in the ignition cylinder failing to recognize the key, replace ignition cylinder.
He told me my key was fine.
I don't know what to believe. There was some double talking going on, not with the tech but certainly with the service advisors.
I know the last time I brought the key to be repaired the locksmith said something about how he can tell I got the key wet and I believe he had to clean off some corrosion on the inside. I did drop it into a cup of soda sometime this past this summer. Stuff happens.
So after 3 hrs and $186 for the "diagnosis" they told me it's an $1100 repair.
$500 for the part (ignition cylinder) and 3 hrs of labor at $179 per hour.
CAN SOMEBODY PLEASE ADVISE?
Meanwhile I never know for sure now if I can make it to work or not and I cant be missing work. I need to do something ASAP.
Thanks in advance, I would greatly appreciate an I formed opinion.
