Hi
When you turn the key, do you hear a single tick or ping from the engine bay?
If you do hear something like this, your starter motors solenoid could be stuck, if you have access, tap the top of the starter motor lightly with a hammer or piece of timber, then try starting,
Also have you tried jump starting?
Also another sound to listen for is a slightly high pitched hum from underneath or rear of the car, this would be your fuel pump, this is what you want to hear, so you know fuel is being sent,
Let me know how you go
Cheers
