Hope someone has seen this before..

The Usual operation with factory alarm fob = press once, bike beeps and indicators flash, turn key, everything light up. all good.
Switch off, immobiliser arms after one minute. double press fob to set alarm.

The other week, i noticed no bike bleep and indicator flash when hitting the button on the fob to disable alarm, I turned the key, & alarm sounded ! pressed button on alarm fob, alarm silenced, bike started OK.

I changed the battery in the fob, no different, so I'm a bit worried I might not get home one time, so I thought I'd try the manual disarm, but..no flashing on the alarm LED.

any ideas ?

Aye, my OE alarm failed in similar way after circa 45k miles - suggest either replace or remove and fit specific blanking plug to wiring harness.
