A flashing green key means your car’s immobilizer system can’t recognize the key program. If it’s a 2007 Honda CRV green key light flashing or for any other Honda CRV car’s problem, try to use another key.
This solution should work the right way. You must contact a Honda dealer to reprogram the keys if the issue persists.
According to a user reported on iFixit,
“Apparently this is a fairly common problem caused by the seatbelt being caught in the door and catching the switch.”
So, if your car unluckily got such issues, you need to check the wiring of the alarm connected to the driver’s side door opening switch.
Just remove the cover of the switch and take it out carefully. Then, check and ensure the wiring connection.
In some models of Honda, like a 2006 Honda CRV green key light flashing issue may arise with a jumping speedometer. When you get this issue with your vehicle, it happens because of the wrong programmed key.
If you insert a key that your car can’t recognize, the immobilizer system prevents starting it. Sometimes it can misbehave with the correct key as well.
To run your car with the valid key, insert the key, but don’t start instantly; wait for a moment and allow your vehicle to be primed, and the green key light gets off. Then, start the car, and it should work without ado.
Some users find a 2009 Honda CRV green key light flashing with or without a glowing engine check light. It’s also the issue that causes the immobilizer system.
Like the improper key with the wrong program or code that’s unrecognizable to the immobilizer, it prevents starting the engine with green key light flashing because of erased key code. Try with a different key to solve the issue. If it doesn’t work, you need to reprogram the key.
The Honda green key flashing 5 times or keeps flashing continuously, won’t start, or turning over causes different reasons. If everything is OK, but your car won’t start with green key light flashing, it indicates an immobilizing system error.
When you insert and try to ignite it, the immobilizer can’t read the code and avoid starting the vehicle. Also, it may be due to the error of the immobilizer system itself. Using another key should solve the issue. Otherwise, you must contact the Honda dealer to reprogram or recode your keys, or it may require replacing the entire immobilizer system.
We have already learned that a wrongly programmed key is the main reason for the green key light flashing. But, it’s not surprising that the issue may sometimes happen for the damaged starter.
