My battery on my 2010 went flat and after charging the battery up I attempted to use my fob to disengage the alarm however it would not deactivate. I got my spare fob and same issue.

After charging my battery do I have to do something specifically to re activate the immobiliser?

FOB Batterys

Well Im back again. I have changed the batteries over on my fob and still no luck. I am going to the take battery out and get it tested. I have a power commander, street tuner and obviously the alarm connected. What do I need to disconnect first before taking the battery out.

Try disarming using the security code then I think it will reset.

Before removing the main battery,

Turn ignition on and then remove the main fuse.
This will prevent the alarm going off.

Instruction guide that comes with bike has the procedures for resetting the alarm and immob

Above post is correct .

This is a little different , You will get less or no spark out of the fuse holder  when pulling the maxi fuse out .

1. Turn igniiton ON

2. Wait for engine start proccedure to complete. About 5 seconds.  ( A few chrips etc, the alarm is now off) .

3. Turn OFF ignition.

3. Pull Maxi fuse out.  (this has to be done within 5 seconds , otherwise the alarm will reset ).     

When you have completed installing battery and connected cables to terminals ,  (I would do a quick test with meter),  just install the maxi fuse back in postion , start as normal, and your good to go !!!!

PS, for the sake of  $3  , put a new battery in your Fob !!!!
