2005 toyota prius The warning light(car with key inside) flashes after I cut car off and take electronic keys out. Should this happen ? It cuts off when I start the car

SOURCE: prius warning light is blinking

This is the security indicator light. Designed to alert potential theives that the alarm is active. It is a L.E.D. lamp, and will not drain the aux battery. Nothing to worry about, this is normal. Hope this helps, and Thanks for choosing FixYa!

your owners manual should show all of the symbols and what they mean.I tried to get one to look at it but no luck...they should be in the manual though

SOURCE: A warning light won't go off on dash.

it is not a safety issues . the chip sensor in the car is defective. if it doesnt anoy you dont worry. if the sensor fails to warn you when the key is left inside then you should be concerned.

SOURCE: dash warning light not found in manual - hot to turn it off

The flashing key-inside-a-car means the anti-theft system is working properly. On page 84 of the 2009 Prius owners manual, the explanation indicates that a flashing key-inside-a-car is normal, and is desired. It should extinguish when the automobile is operating. It may be distracting, but it's a good thing!!

Hmm, I'm not sure what a main chip is but, there is a few reasons for this problem.

1. ABS Sensors - there could be something wrong with a sensor and/or the wiring to them
2. The wheel bearing speed sensor in a wheel is bad or intermittent which then tells the computer that wheel is traveling at a faster or slower rate of speed then the rest which in then the computer turns the abs light on.
