Have Honda Questions? Ask a Honda Repair Expert.
Which light is on? Is it the green light that looks like a key? If so is it flashing?
If the car just starts and dies right away I would say it is an immobilizer issue and if a locksmith has equipment to try and reprogram the key you can try that. It could also be a fault in the system where the dealer will need to check and repair it.
If the car does not turn over at all the battery my be low or bad which would cause a voltage issue that will make the key light flash. You could try to jump start the car if that is the issue.
I hope some of this information helps you.
Yes then you could have a key issue, You may want to call and see if a locksmith can do it for you.
It should actually start and die which does make me think it may be more than just a key issue. You will not be able to reprogram the keys yourself as it does require special equipment to do.
