PADLOCK SUPPORT

If moisture on the lock keypad freezes so that a button cannot be pressed, we recommend warming the lock keypad between gloved hands for a short time to melt the ice until the button can be pressed. The lock should then resume normal operation.

Check to see if the firmware on your Padlock or Lock Box is up to date:

1. Sign into your Master Lock Vault Home account
2. Select your lock from the “Locks list”
3. Select ”Manage Locks”
4. Select the Gear icon in the top right corner
5. Select “About this Lock”
6. If a firmware update is available, you will see the message “There is a firmware update available!”
7. Press the “Download and Install” button
8. Press the “Install Update” button
9. Make sure the lock is awake and remain within 2 feet of it while the update installs
10. You will be notified when the update has successfully completed

The 400EUREC series battery should last at least 2 years in Touch Unlock Mode and 4 months in Swipe Unlock Mode with regular use.

Master Lock utilizes Bluetooth Smart technology to facilitate wireless communication between locks and mobile devices. These locks and lock boxes are designed in a way that prevents the threat of Bluetooth hacking that exists with some other Bluetooth products.
