Hey mate, not sure if you're still looking for an answer or if this is any help but i found this in the copy of the manual i have....
HOW TO DEACTIVATE THE ALARM
To switch the alarm off, press the remote control
button on the key.
In countries where admitted by law regulations, the
system is preset for an emergency procedure to be
carried out when the alarm does not turn off (due to
flat remote control battery or system fault):
❒ open the door after unlocking the lock with the key,
❒ fit the key into the ignition switch,
❒ turn the key to MAR.
To reactivate the alarm after the emergency
procedure, turn the key to STOP and remove it. Then,
press twice the remote control button: first press will
re-align the system (this because the last operation for
excluding the alarm was performed using the key and
not the remote control), the second press will
reactivate the alarm.
Not sure what countries this applies to but changing the country programmed is easy, search this forum and you'll find how to do that if you need to. If that works just skip the 'reactivate' bit and save yourself getting that key fixed. Much as i love my uglybug i doubt there is much need for it to be alarmed
