I cannot turn off alarm,and immobiliser on my 1996 vauxhallfrontera sport?

i had same prob other day after renewing battery
after a hour of trying i decided to check all fuses
the hazard lights where flashing all time but no alarm untill i turned ignition to on
i found taking the central locking fuse killed the alarm going off
so i tried to start anf hey presto sorted.
no central locking tho
