I'm not modding, I'm improving
I have started to get the same. From memory of other recent threads it is the battery for the alarm, not the car battery. I too changed my battery not too long ago (matter of months).
I believe it is a fairly easy job, but requires soldering a new battery in place. Sure someone will be along in a second to give you more info.
