Non start hazards on

Ok so got to my car this morning went to start and nothingy hazards turned on and stick on even if pressing the button. Grabbed spair key fired for a second then turned of and the same happened.... Where do I start before trying to get it to a garage ? Many thanks Scott ( I have done a search but couldn't find anything directly linked to my symptoms)

I had this before, it's the alarm going off silently, no idea why it did it. All I did was blast it with the fob over and over. Is there a red key symbol on the dash when you try and start it?

Thanks for that I will try that when I get in from work disconnected the battery so it dosnt go flat. After reading could it have anything to do with the red plug in the ECU ?

This one has nothing to do with the red plug....how does the red LED on the dash behave?

ok so went to get something out of the car and thought i would try to see if it will start..... and what do you know it started, took it for a spin turned it off and on and everything is fine again. Would it be worth paying the £60+ it would cost to have a diagnostics done or could it possible have just been water damage when washing the underside of the engine?
