Car Alarms: Higher pitched chirp, never happened before, clifford matrix, chirp

Question
Hi, I have been away for over 3 months and came back to a dying battery which I had to be charged in order to drive my car and get it changed. I had someone starting my car every two weeks, who would have to charge the battery in order to do so.

I bought my car used and it came with a Clifford Matrix 1 alarm system (I had to research to find this because nothing was given to me, no manual or name or anything).

Now, before changing the battery I noticed that, when arming the car, it would chirp twice as usual, but the second one was higher pitch, and weak sounding. I figured it was related to the battery being almost dead. However, it continued on after it was changed.

Yesterday my remote didn't work and I figured that the high tone chirp must of been a warning about my remote battery being low. I was wrong because changing it still didn't work. So I decided I would open the door regardless, knowing that the alarm would sound, and my cell phone. Well the alarm didn't sound. But unfortunately, I couldn't start my car either. It was like the alarm system somehow disarmed itself but not the anti-starter function.

Finally I came back to my car an hour or two later and decided to try the remote again, and it worked! Still did the week sounding chirp on the second beep though. I tried looking at the manual for the remote (which I found online) and I couldn't find anything about a higher-pitched/higher tone or weaker chirp. I also did some research online with no luck.

Can you tell me if you know what this means and if it had anything to do with why I couldn't get in? Or maybe the person who was starting my car inadvertently changed the settings and that the remote was simply out of sync? By the way I'm not aware of any valet switch in my car (according to the manual I should have one) so all I have is my remote.

Let me know if you can be of any help, thanks for reading!
