Frequently Asked Questions

What does 'module not found' mean on my Yale smart lock?
This error indicates that the network communication module (WiFi or Z-Wave) is either missing from the module bay, not properly seated, or has failed. The lock will still work manually but smart features won't function.
Can I still use my Yale smart lock without the network module?
Yes, your Yale smart lock will continue to function for manual entry using the keypad, physical key, and any programmed user codes. However, you won't be able to control it remotely through smartphone apps or smart home systems.
Where can I buy a replacement network module for my Yale smart lock?
Replacement network modules can be purchased directly from Yale, authorized dealers, or major home improvement stores. Make sure to order the correct module type (WiFi, Z-Wave, etc.) that's compatible with your specific Yale lock model.
How do I know which network module my Yale lock needs?
Check your lock's model number and original packaging, or look in the Yale app settings. WiFi modules enable direct smartphone control, while Z-Wave modules work with smart home hubs like SmartThings or Ring Alarm.
Will I lose my user codes if I remove the network module?
No, removing and reinstalling the network module won't affect your programmed user codes or basic lock settings. These are stored in the lock's main memory, not the network module.
