Secondary air injection system fault.

This is the anti-theft system working properly. The vehicle has lost communication with the key and it this causes it to go into theft mode. This can happen randomly, or if the battery in the vehicle was replaced. Unfortunately this means a trip to the dealership to have them reprogram a key.

what is the make and model

have battery tested if good fully charge,then check all relays and fuses.

Try turn key on car but not start for few min.Call dealer for alarms ask ththem.Or get online.

could be several things. check the plugs first to make sure they are not fouled with fuel and also check to make sure the security light is not flashing.

If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.
