if the central lockin is operated by ur alarm system, it would b fuses on the actual alarm unit. not the car. so trace all the wires thorough ur alarm to find the fuses, 1 by 1 take a fuse out, see if the cent lockin still works. if a fuse is taken out and locking still works, place it bak and try another
if u do not hav an alarm, use the same method on ur fuse box
