HI all i'm new to this site purchased a 2007 hse petrol in February have had no issues until yesterday,after driving home from work parked up shut down and locked car, next morning went out doors unlocked fine,put key in ignition dash lights and key in ignition warning came on as door was open, moved key to position 2 all lights came on waited for beeping to stop as i have every other day move key to start and everything went out no start.tried several times but same issue, all interior lights coming on when door is opened, however when using the push button unlock on key fob there was no flashing of hazard lights and the central locking seems very sluggish,After a day at work tried it again and still all the same issues,
Any help would be much appreciated.

 

What condition is the battery?
