FAQ

Can I use key fobs without a smartphone?
Yes - fobs are programmed via the app but used independently. Once programmed, the fob works without the phone. Users tap the fob on the lock reader.
What happens if I lose my key fob?
Immediately deactivate it in the app. The fob is instantly rendered useless. Buy a replacement fob and reprogram it. Keep backup fobs in a secure location.
Are key fobs more secure than PIN codes?
Comparable - fobs use encrypted communication. The main risk is loss of the physical fob. Fobs with activity logging provide an audit trail of every use. For more information see our Smart Lock Insurance Approved Models UK.
