FAQ

Can I put a smart lock on only one French door leaf?
Yes - the active leaf gets the smart lock. The passive leaf must be manually shootbolted. Both leaves must be secured for full security.
Do I need two smart locks for French doors?
Not necessarily - one smart lock on the active leaf with a manual shootbolt on the passive leaf works. Dual locks provide full remote control of both leaves.
How do UK seasons affect French door smart locks?
Wooden French doors swell in summer and contract in winter. Check alignment quarterly and adjust hinges to prevent stiff operation or auto-lock failure. For more information see our Smart Lock Maintenance and Troubleshooting UK.
