hi thanks for the previous replys.
this one is because i have no alarm key. can this car arm itself ,as in disconnecting the battery,or by some other means.
having no alarm is not a problem for me.can i disable alarm if it goes off. this car has no owners manual to find a code.
bought it from a used car dealer with no records
Thank you Rich

I never use the alarm key because sometimes it goes off when I unlock the door with it. No interest in fixing the problem, since the probability of theft has become very low.

Anyways, I cannot imagine you would need it for anything.
