Keyless beep
 

2 days ago my battery died because I left the lights on. The next morning I gave it a jump start. The cel turned on but eventually went off.
The problem I have it's that usually when I lock my car it gives me a beeping noise. To tell me if it locked or not. Usually it beeps once if it did. And if it didn't it beeps 4 times. But now it beeps 8 times and it locks.
Does any one know what's wrong?
