WHY DOES THE HORN AND LIGHTS GO ON AND OFF WHEN I CONNECT BOTH BATTERY CABLES?

I tried to install a new battery because the old battery kept going dead if I didn't drive the car for a week. I put on the positive cable and when I put the neg cable on it acts the same as if I pressed the panic button on the remote.

Do you
have the same problem?
Yes
No

You are triggering the alarm when the battery is connected. You have to connect the cables and then shut the alarm off.
