Default Question about a dead battery and security system

Hi everyone, I have 2007 Sportster 1200 custom with the security system sitting in my garage. My bike hasn't been used in a while, and the battery is now completely dead (unfortunately I don't have access to any power in there to keep the battery alive).

The last time I changed the battery, I first disarmed the security system by turning the ignition key (powering the bike), then pulled out the main fuse. I then replaced the battery and put the fuse back, and the security system didn't complain since it had been disarmed.

Right now, the battery died while the system was armed. And by dead, I mean turning the key doesn't do anything at all (nothing powers).

So, my question is, in what state is the security system? If I change the battery now, what will happen when I put the main fuse back in, will the alarm go off because it will wake up and think it's armed?

Thanks for the help.

Do exactly as you did last time. Will the alarm go off? Quite possibly, but that is why you hold your fob in your teeth while reconnecting.....

2007 year has a buttonless alarm FOB, as long as the FOB is with the bike when it i powered up it should sense it right away and disarm the alarm. Just make sure you have a good battery in your alarm FOB and it will be transmitting when you power that puppy up.

you will be fine. like mentioned above, put a new cr 2032 battery in your fob(s) and have one around the bike when you swap out the bike's battery.

https: // www. harley-davidson .com /content /h-d /en_US /home /owners /om /2007 /en /SPORTSTER /file-5 .html

all the items in red can be modified to suit your needs
  • year (e.g. "2007"): 2005 and up
  • language (e.g. en = 'merica): standard two letter abreevs
  • model family (e.g. "sportster"): c'mon man
  • file [section of owners manual], (e. g. 5 = security): 1, 2, 3, ... 14
if you have a siren, the battery in it may be shot, may not be. it's a 9v rechargeable that draws a charge from the bike as it runs.

Awesome, thanks for all the replies.

Haven't replaced the batteries in the fobs since I got them (4 years ago). I guess I probably need to change those just to be sure.
