1998 Renault Clio RENAULT CLIO CAR ALARM PROBLEM!

Electrical problem
1998 Renault Clio Manual 75000 miles

Hi,

I Just Recently purchased a renault clio 1998 1.2 mark 2 car.

i held the Central Locking Button and it activated the alarm i then held the button but it now will not deactivate
the keyfob i have doesn't work and i have tried to change batteries but still no luck!

So everytime i opened or stayed in the car it kept activating the default alarm is a sigma

so i don't know the pin number and for the little 9 digit led keypad

so i found the fuse for the car alarm and took it out and it then shut it up and saved my ear drums from exploding then when i came to start the car on ignition 2 it triggers so i cannot drive the car
going round town with hazards flashing and siren.

the alarm was already deactivated and i can now not reset it i have taken my battery off and everything i can think of

can anyone please help me disable / reset or do they know where the main control panel box is for it as it is sepearate and fortunatly doesn't work with the immobiliser.

as i will disconnect the control panel if i have no luck resetting it.

Thanks
