Update Firmware is the process of updating the lock firmware through NFC. Key Butler will connect to the server automatically and check if any new version available for your locks. It is highly recommended always update your locks to the latest version.
Open Key Butler, and select "Update Firmware"
On the Lock List page, Key Butler will connect to the server and check for any available firmware of your locks
Note: please turn-on Internet connection for the version check.
Click on any lock with status of "New version available"
A downloaded firmware can be reused for all locks of the same model. If the firmware is not downloaded yet, click on the "Download" button here to download the firmware.
Note: please turn-on Internet connection for the downloading.
If the latest firmware is already downloaded, the button will show "Downloaded". Press the next button on the top-right corner.
Please enter setup mode (the method depends on lock models; some models require pushing the Setup button on the lock, and some models require additional PIN; please refer to the lock manuals for details), keep the screen at this page, and tap your phone to the lock. You will see the progress bar moving forward. Key Butler is programming the new firmware into the lock.
Note: make sure both your lock and your phone have sufficient battery power before this step.
Note: If you lost NFC connection during the process, tap again; As long as the disconnection is not too long, the updating procedure could be resumed.
After the progress bar goes to 100%, the updating procedure is completed. Your lock is updated to the latest version now.
After the updating process, please tap the lock again to sync information from the lock, including the firmware version information.
