Recently, I have had 3 instances where my car alarm suddenly goes off. All times, my car was parked in my garage, unlocked. The keys were sitting on the table and had not been touched.

The only thing is that I think the battery in my remote is started to get low I think but I don't really see how that would cause this issue.

Maybe one of your door sensors is going bad and causing random alarm issues?

If this was the case the car would haved to be locked and armed.

Is it possible that because I'm running low on batteries, the remote is sending out random signals?
I'm assuming the remote sending out the panic signal is the only way the alarm would sound while it is unarmed

I guess it could, though I'm not sure. Could it be that the panic switch is loose/broken causing it to make random contact? I would try changing the battery first to see if it resolves the problem.

Take the battery out of the remote(s) and don't use them for a few days. This will eliminate the remote from the equation. If it still occurs then you know its not the remotes.
My bet is that its not the remotes.

Yep, that's what I'm trying right now.

but if its not the remote, what would cause the alarm to go off while it is unarmed?

Of course, taking out the battery and disabling your remote is a good idea.... But also, I got my car with TWO sets of original keys and remotes.... If you think your remote battery is low, take it out and start using your other remote, see what happens.... If using the 2nd remote still does not eliminate the problem, the car has an electrical problem, that's obvious.

While taking out the battery, it happened again while the circuit board was in my hand. I saw the light blink and the alarm went off. I notice if I just touch the panic button without really pressing down, the alarm will go off, yet with the unlock button, I have to press with a good amount of force to get it to activate.

So I will try using the other remote for now and see if the problem goes away.

Yes, I bet using the spare remote will eliminate the problem, which is probably caused by a faulty panic button on your original remote.
