alarm going crazy

[bloomsdayfan]

the keyless entry battery went dead about a month ago, so I've been unlocking/locking doors manually. A week ago I unlocked the door and the factory alarm went off with no way to turn it off other than remove the horn fuse. I unhooked the positive terminal from the battery for about 5 minutes to see if that would reset things to no avail. Is there something I can do to reset the car to a "normal" state so I can reprogram the transmitter with the new battery, or is this even a keyless entry problem?

Put the new battery in and use it. the programming in the remote doesn't change so the van should see the remote once you install the new battery.

I'll give it a shot and let you know. Thanks for the advice.
