The red flashing light on my Honda City dashboard stopped working even after locking the car. Plz what is the problem and solution.

If the engine light is flashing, you need to connect a Code Reader to it.

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.

try using key in door lock to unlock & disarm.

The red light flashing may be the engine immobiliser that works in proximity to the key. Have some one check the alarm system

The red light should be the anti-theft system. Do you have a key fob to open by remote ?
Is the driver's door the only door with a lock cylinder ??

Sounds like your catalic converter is trying to stop up. When you drive it this heats up and causes your car to vapor lock and quit running you let cool down and it will start back and run for a while. You can take it to a muffler shop and they will check it for free. This could be any number of issues but this is where i would start.Best of luck to you, Thank's for using Fix Ya.

Have you tried changing the battery in the remote? You should be able to hit the panic button to stop the panic

I would have to say it is the anti-theft light since it only flashes after you lock the doors which if this is that is normal,shows system is armed. However when looking through the owners manual on a 2003 model it shows it as THEFT and not a key,2002 shows the same,however 2004 shows a lock. The only thing I see that even closely resembles a key is the temp warning indicator.

You can go to this website and pick owner guides on the left task bar,then input your vehicle info,then pick get owner guides,then pick the owner manual and it will show you a picture of the instrument cluster and what everything means.
