2003 K1200LT, factory alarm.

Bought the bike about three years ago. Previous owner didn't have a remote alarm fob when I bought the bike.
Purchased two used remote fob's, got the alarm codes from my local BMW dealer, and successfully programmed them.
The alarm has been working fine for about two years.

Not sure if this is related but the "low" pitch horn failed about a month ago.
(We have two horns up front, one high pitch and one low pitch horn).
Sounds very "tinney" when only high is working.

Seems like that was about the same time the alarm started acting up.
I've replaced that faulty horn. Now both horn's are working well.

Will try and describe what's going on with the alarm.

I use to get two distinctive tones (high / high) when activating the alarm.
I'd also get two tones (high / low) when deactivating.

Now I don't get any activating or de-activating tones.
The turn signals still flash and the LED up front will flash when I activate the alarm.
Soon after activating, the LED stop's flashing and a faint sounding alarm siren goes off (as if the alarm has been activated).
It's no louder that someone whispering to you. More noticeable if I open the seat and put my ear near the siren.


When de-activating, the turn signals flash, the faint siren sound stops, then the LED cycles in a 5 flash, pause, 5 flash, repeat..

Turn on the key and the LED flashes two times, stops, and it's ready to start.
Very strange, bizarre behavior to me.

I've tried disconnecting the battery for a few days.
Tried pulling the horn fuse (which btw, also lowers the volume of the faint alarm sound when I pull it.)

Hoping there might be a way to try and reset the alarm module.
Read through all the alarm manuals and write-ups I could find but none mentioned a reset.

If you've read though this and have any advice to pass on, I'd appreciate it.

Regards, Ken

I know a lot of you have bypassed or don't use the alarm but I like having it.
Would like to try and reset the one installed now. Next step would be to buy a used alarm on eBay.

As far as I know there is no "reset" for the alarm. The internal battery may be failing and there is no way to replace it as it is potted in the alarm. Your best bet is to remove (bypass) the unit or replace it with a new one.

Thanks JZ.

You're post made me think...
If I triggered the alarm, then pull the #3 fuse to let that faint siren sound completely drain that alarm module's internal battery.
What would happen after installing the fuse?
Doubtful but maybe it would then take a charge?

Used alarms might not be a good option considering age. The internal batteries would all be over 10 years old.

I think the battery in my alarm went bad last week. I keep my bike plugged in to a 800MA battery tender ( water proof for out side ) all the time ..went to go & my battery was dead... I took the alarm out, put 2 jumper wire on the alarm plug wire. got the battery on the bike recharge ..now all is good.

I don't know what happened ...but I didn't use the alarm anyway..but all is well now .

And a big Thank you John for puting the instrutions on this sight to bypass the alarm .:wave

Tried my fuse pulling idea to drain and attempt an internal battery re-charge.. No luck.

After pressing the alarm fob to activate the alarm, the LED flashes twice and a few seconds later, I hear the faint sound of the alarm siren...

The bike is ~14 years old but....
Assuming the internal battery is the issue, kinda ticks me off that they put a non-replaceable battery inside the module..

If I find new one to purchase, I'm guessing it's probably been sitting on someone's shelf for 10+ years (with a 10+ yr old internal battery). Alarm was made for 98-04 models.

Might be moot, the part is obsolete.

Searched BMW part #65757655900 and found - ENDED = the part has been discontinued (no longer available).

Sounds like time to bypass.

I had a somewhat similar issue recently. I have never used the alarm since getting the bike. A few weeks ago I replaced my bike battery and when I reconnected the new one, it set off the alarm in my garage. Since the key fob battery had long given up the ghost I couldn't shut the alarm off until the fob battery was replaced. The alarm still works OK but bypassing it now might be the smart thing to do so I don't get left stranded somewhere should it happen again.
