Replacing battery

I just replaced the battery of my Exige.
When i replaced it and opened the door the blinkers did flash like a alarm system.
Normally when i started the car i turned the key,then pushed the button on the key and then started the car but i never saw the blinkers flash,is this normal?
Also when i started the car the motor won’t turn on,it sounded/smel like overfueled.When i turned the key again it started when i was playing with the throttle and then it runs smooth.Do you need to program/setup sensors like tps sensors when the battery is replaced?

How’s the car today? A battery change will not normally cause any problems my friend.

Didn’t try the car today,i think he will be ok.
I didn’t realise that the blinkers were flashing when you push the key button,maybe its normal but have never seen it before.
Is it that my car has the optional alarm system or is it normal at any Exige?
