2. Reset Method

Disconnect vehicle battery. Turn ignition switch to on.
When the keypad lights have stopped flashing (this maybe immediately after disconnecting the battery, depending on the state of charge of keypad module battery), wait a further 5 mins before turning off the ignition switch.

After turning off the ignition switch, have someone reconnect the vehicle battery while you hold down the "0" and "#" buttons together. When the vehicle battery has been reconnected, you can release the buttons.
Then hold the "0" button down (it will beep while holding but this is normal)until you see exit countdown delay begin to flash and then release the button.

Allow the system to arm itself then turn on the ignition and enter the user code to disarm the system.
Keypad system is now back to normal.
