Hi sandramc1,
Symptoms indicates the battery terminal connections are not clean or secure. Remove, clean and retighten and retest.
When battery intermitently loses contacts, the alarm would be armed. If you do not have the keyless remote, close all doors and use the key to lock/unlock the doors and check if the alarm is disarmed.
