Blinking "key" dashboard indicator?

Does anyone know what a blinking "key" on the dashboard of an Odessey means?

My car runs well, the the "key" symbol suddenly began blinking 5 times when I turn the car OFF.

(The manual only talks about blinking when you turn the ignition switch ON)

Thanks

it's normal

its the imoblizer symbol, it just shows your vehicle anti theft is working properly...
