did you loose the guide. its here
http://justgivemethedamnmanual.com/honda/honda-accord-coupe-owners-manuals/

it automaticaly sets when you lock the car.
so you want to defeat the auto set. ,
Honda dont want you to....
so..
the MICU does that. it is fully integrated into the cars systems.
includes, door left open warnings, etc.

if you attempt to kill it, many bad things will happen.
i suggest asking HONDA that question.
drive there , ask service, if it can be done.

the manual does not mention defeating it .

Either unlock the drivers door with the key, or turn the ignition on and try to start the car. one or the other should disarm the alarm

The 2003 Sonata is equipped with a 'starter KILL' burglar alarm system with disables the starting system (using a N/C 'contacts' configuration instead of a N/O contacts configuration). N/C=Normally closed, and N/O=Normally open contacts. When the alarm goes off with a MY Sonata, the only way to DISARM it is with the key fob (remote) originally programmed for it (unless you purchase a new remote & have it programmed for the vehicle at an authorized Hyundai Service Department). NOTE: So long as the keyless entry & burglar alarm system is functioning/operating normally, the alarm will keep going off and the STARTER KILL function will still prevent you from starting the vehicle. One option is left without purchasing a new remote and having it programmed.
1. When the alarm goes off, get into the vehicle and insert the ignition key into the ignition.
2. Turn the key to the 'RUN' position (NOT the ACC position) and wait for the alarm to STOP (usually about 3 to 5 minutes).
3. The engine should then start using the ignition key.

If this procedure doesn't work, the problem will need further diagnosis by a qualified/certified Hyundai Service Technician.

Hope this helps

try locking and unlocking drivers door lock with the key

If you have a security system and the car wont start then your starter kill is the culprit, if the starter kill is active then your car will not crank, you must disable this by pressing the unlock key in your remote twice continuously , check your LED bulb in your dash or where ever it is mounted if you have one that is. If you dont, see if your parking lights flash when you press the alarm remote keys. Physically disabling a starter kill is not something you want to do with expert help , you must have a car audio tech do this for you or someone who is physically there to help you, I cant help you from Fix Ya , it is too much technical information and a delicate procedure that you must do under your dash if you can locate the alarm brain. All this if its the starter kill if not then you have a mechanical problem, check your starter, battery, alternator, ignition and obviously as silly as it may sound gas. Its probably an electrical issue like your ignition, battery, or alternator. Check Maxi Fuses under your hood or under your dash.Ignition fuses etc.

Good luck.

The key switch went bad in my 88 Honda DX.I found out the problem quite by accident.Try playing with the switch very carefully and see if it will start for you! Yes the engine will spin buy it will not feed the coil so it will start.Good Luck!

put your key in the ignition and start the car it will go off

1991 honda accords had a recall on the ignition control module this in the distributor more commonly known as the igniter. call a honda dealer with your vin number and they will tell you yours has been replaced or not. Mine was so had to to buy one at auto parts store for $60 .kinda expensive for this little chip with 4 wires.
