I just buy a corllola 2009, ce. I notice that the security light will flash once I turn off the engine and it will flash all the time until I insert key again. The dealer tell me this is immobilizer system functioning. I am wondering if it has to be this way? If I leave my car there for 2-3 months not driving it, it will also flash all the time? I do not see the light flash in dealer's showroom.
