Programming and Troubleshooting Guide for the Kwikset SmartCode keypad deadbolt line — Mastercode setup, user codes, and troubleshooting.
Programming and Troubleshooting Guide for the Kwikset SmartCode keypad deadbolt line — covers setting up the optional Mastercode, adding user codes with Mastercode enabled, and troubleshooting the turnbutton, keypad, smart home pairing, and battery.
Using a Mastercode is an optional, added-security measure. It is not enabled by default. A Mastercode is used to add and delete user codes, but it cannot unlock the door (unless the same code is also programmed as a user code, which is not recommended). The Mastercode must be 4-8 digits.
Programming timeout: if no button is pressed for five seconds, the system will time out and you'll need to restart the procedure.
If programming is successful, the keypad flashes green once with one beep. If unsuccessful, the keypad flashes red three times with three beeps — make sure the Mastercode has not already been programmed, and attempt again, entering the same new Mastercode in steps 2 and 4. Note: the lock will time out after five seconds.
The procedure for adding user codes is different when the Mastercode is enabled. For instructions on adding user codes when the Mastercode is disabled, see the Installation and User Guide that came with your lock.
If unsuccessful (red flash x3, three beeps), make sure the user code isn't a duplicate, is 4-8 digits, and that a valid Mastercode was entered in step 2.
Symptom: The turnbutton cannot rotate; the lock beeps, the keypad flashes red, and the door cannot lock or unlock.
Cause: The set screw in the lever was not fully tightened.
Fix: Fully tighten the pre-installed set screw at the bottom of the interior lever.
Install a fresh set of batteries and turn switch #3 to ON. Test each button (one at a time) and listen for a beep on each press. If beeping is not heard on all buttons, contact Technical Support.
Keypad lockout: if three incorrect codes are entered within one minute, the keypad locks for 60 seconds.
Anti-tamper alarm note: some locks sound an alarm if the interior is disconnected from the exterior. If heard: remove the battery pack from the interior, remove the exterior assembly from the door, reconnect the cable between exterior and interior assemblies, reinstall the battery pack, then pair while interior and exterior are connected.
