Alarm module batteries

[GSite]

Hi All,
Had my 2013 Twin Cam GSA from new and the factory alarm module batteries have never been changed, nor has there been a warning on the dash. Thinking about changing these if they are part of the immobiliser circuit and would prevent starting the bike if they were to go without warning on a longer trip away, anyone know if this is the case ?
Take it that these are CR123 lithium 3V none rechargeable.
If I change them, does the alarm module need a reprogramme and can this be done using a sequence of button presses on the bike or can I do it via GS911 tool ?
Thanks in advance.

I just replaced mine and all was fine. I did have the DWA warning on the dash to tell me the batteries were low though.

The batteries in the alarm unit have nothing to do with the immobiliser function, that is handled by the BMS (engine ECU).
They are more of a backup for the alarm if the battery is disconnected.

Never even considered mine (2007 bike) alarm still works almost perfectly, no immobiliser issues.

Sometimes it’s a bit hard to disengage the alarm from the remote if the bike has been sitting for a long-ish time.
In those cases it’s faster to just switch it with the key and it will disengage automatically.

Could it be batteries?
I have no warning on the dash whatsoever.

Thanks, good to know I won't be stranded if the batteries go.

screwfix sell the batteries

the factory method to get at it - is to drop the rear mudguard down... but if you have the GSA metal pannier brackets there's quite some faff in doing that - three filister screws drop the bracket off the mudguard then you can better see the 4 screws for the alarm box - the silly red silicon seal is a pain, and inside the lid is tangled with the battery wire connections - a tiny PC fan style white pop off connector - try getting a picture before it falls off and you forget how it goes

This is good advice. When I did mine, one of the screws in from the top, sitting deep in one of those recesses in the plastic cover, decided to be a pain.

If I did this again, I'd flood those screws in the deep recesses with something the night before. It might help

those 4 little lid screws are a funny head size - a right faff to get off / and on again

Many thanks for the advice guys.

Interesting because I was just on a mission last time. About to fit a dash cam and I want to get this plastic cover off again to route the rear camera cable. Not looking forward to it! But maybe I'll pay more attention to the head - after drowning them in plus gas the night before!

the alarm lid was odd cross head size

the mudguard is the torx stuff BM like to use everywhere (probably T27) - early bike's have some filister screws (battery end) on the inside that are a pain (from the top, at the bottom of the tray)

the 2010 one put them all on the bottom (outside) where you can see and reach
