Does it do it with internal sensors disabled? Not familiar with your car, but handbook should say how to do it, either by button inside, or certain key fob press technique etc.
if not, the issue is with the internal sensors.
if it does, then Check boot and bonnet and door switches for poor contact, movement, bad connection and power supply.
SOURCE: 1996 Jeep Grand Cherokee alarm keeps randomly going off.
this happened to me recently with my 96 grand cherokee. the battery got drained by the alarm going off randomly at night. i pulled the fuse for the horn so at least my neighbors would only be bothered by flashing lights. then i couldn't jump the car because the alarm was still going off. i hooked my car to jump it to another car, and then i had to deactivate the alarm first by putting my key in the driver side door and unlocking the car. then i left it hooked to another car and still getting power but didn't jump it for at least 5 minutes in case the computer needed to reset. then it jumped fine. from what i've read online, this is a common problem that can be avoided if you stop using the power locks and always manually lock and unlock the doors with your key. its a little annoying, but apparently the power locks are connected to the alarm issue. hope the same works for you.

1957>??? really?
all alarms are a box with a processor in it, a computer, or puter.
the alarm brain.
so like all computers, garage in , nets you,? garbage out.
called GIGO, in the business.
on newer cars 07+? they will tell you what is wrong, using a scan tool
but many old cars , (my big beef) will not. (best is to kill it forever )
(imagine, all 6 billion cars on earth all with false alarms, a world H3LL that , huh) mines off all the time. nobody listens to them. ever.
fixing old alarms with out my special tools is very very hard.
if lucky , inspect all sensor wires, then replace all switches.
old switches fail and for sure 1957 LOL !!!!!!
in my shop I have a voltage (and others) data logger.
i can connect my logger up and then beat up the doors.
rattle them, even drive and see them mess up.
it logs to a flash card.
old wiring and parts on old cars, all fail.
due to wear and corrosion or water ingress.
some alarms have shake switches, that can tip.
the FSM for your, explains all this if alarm is stock.
nah 1957 hand none. right?
the FSM book covers all tests of the alarm.
get one.
if car is not really 1957
then login to alldata.com and see your stock alarm
if not stock , then post all sticker data on side of it.
or photo it and post it.
tell more get more ,like WHAT CIVIC EXACTLY, there are sub models.
