can i over-ride my immobaliser Audi 80?

my fob wont open my central locking on my L reg Audi 80, changed the batteries and it does connect with the car(makes the sound). if i open it using my key the alarm sounds and wont let me start the car. any way i can disconnect the immobilizer and just use the key? managed to locate the actual alarm in the boot and disconnect it, need to move it before it gets moved!!!
