Key Immobilizer blinking


My 2001 Civic EX has 65000 miles. When I start the car, key immobilizer is blinking continuously. Engine is starting and running normally. Some times the blinking will goes off after engine started.I tried with the other key also. Same thing continuing. Please give me some solutions to stop it.

I think your owners manual will tell you when this light is blinking, I wiil not speculate

Thanks for the reply. Owners manual says, the engine will shutoff, if different key is used.
In my case engine is running.No other problem. Whether I have to consider the continuous blinking light or ignore it?

I think the continuous blinking is telling you your immobilizer system is inop
