If I were you, I would follow the link to disable it, then follow these steps to remove the module. Then no more alarm, ever...
You simply:
-Disarm the alarm by either unlocking the driver door, or ground the factory disable wire if your alarm is not functioning correctly (or the tailgate option)
-Unscrew the security module from the backing plate and let it hang down for easy access(The module is located to the right of the steering column w/ 2 screws holding it in place. But at this time do not unplug the main harness, or any adjacent connectors.
-Start the vehicle and let it run for a minute or so.
-Pull the red connector on the module.
-Now turn off the engine, and then disconnect the battery, then turn the ignition switch to start to get rid of any residual.
- Reconnect the battery, and your good to go. Way too easy huh?
