i think if you just unplug the connectors to the ''brain'' under the dash, the sysytem is disconnected and will not interfere with the operation of you car.
(except for maybe your door locks.)
but i agree wit cougar,
it sounds like you have an intermittent power problem.
every time the system loses power it thinks you are trying to steal the car.
and when it gets power back, it triggers the ''alarm''.
it either interrupts the ignition if you have the ''alarm part'',
or it simply triggers the flashing parking lights if you only have the remote entry part.
look for the brain under the dash.
it is a black box about the size of a thin paper back book.
it should have one oe two wire connections (white) on the side.
follow the wiring back from the ''push button''.
btw, if you have the push button, you most likely have a subaru alarm system.
