Change the battery in the fob(s) even if that isn't what's triggering your security light. They are at least three years old and many don't last that long. If you change the batteries and still have the problem, have a dealer check the diagnostic trouble codes, or you can do it yourself.

Procedure to check codes yourself:
Odometer Self-Diagnostics DTCs (Diagnostic Trouble Codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing speedometer, tachometer, TSM/TSSM /HFSM, ECM and ABS DTCs. The Radio DTCs are retrieved through the radio and displayed on the radio display. See Table 2.
Turn Ignition switch to OFF & Run/Stop switch is to Run.
Push odometer reset button in & hold.
Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear.
Push the odometer reset button once and you will see the selection menu "PSSPtb" with the first P flashing.
Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t to b and back to P, etc.)
P --> ECM (Electronic Control Module [EFI])
S --> TSM/TSSM/HFSM (Turn Signal/ Turn Signal Security Module/ Hands-free Security Module)
SP --> speedometer
t --> tachometer
b --> ABS codes
To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTCs the code will be displayed or the word “none” will appear if there are no DTCs. Push the odometer reset button again to view additional codes if they exist.
Record the codes.
If DTCs are NOT to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' is displayed. Release the odometer reset button. Turn OFF the ignition switch. Perform a road test then shut your bike down. Recheck the DTC’s again by repeating steps 1 to 7. If the code is current it will reappear. Historic DTCs are stored for 50 ignition cycles before cleared. The security lamp will only indicate the existence of historic DTCs for two ignition cycles.
If DTCs are to be cleared for that module, press and hold the odometer reset button until 'clear' is displayed.
Press and release the odometer reset button to continue to the next module.
Turn Ignition switch to OFF to exit the diagnostic mode.
