Check battery for condition including load test and clean battery terminal ends first.

Try a different key if you have one as yours the diode may be bad in it. Then check fuses under hood then scan for codes

Did my car originally have a keyless entry, Because when I bought it, the previous owner didn't give me one, and the keys he did give me don't have the diode inside, Could that be the problem?
