A smart lock is a long-term investment, and a little care keeps it fast, reliable, and looking new for years. This smart lock maintenance guide from Covlor® covers the simple routine that prevents most problems before they start.
Keep the Sensor Clean
Wipe the fingerprint sensor and keypad with a soft, dry cloth every few weeks. Dust and oil are the top cause of misreads, and a clean sensor reads first time.
Mind the Batteries
Use quality batteries, replace them as a full set when alerted, and never mix old and new cells. If you leave the property for a long time, fresh batteries beforehand avoid surprises. See our battery guide.
Update the Firmware
Open the app occasionally and install any firmware updates. These improve security and reliability — an easy, free upgrade.
Check Door Alignment
Twice a year, confirm the deadbolt slides into the strike plate without force. Misalignment strains the motor and drains the battery; a small hinge or strike adjustment fixes it.
Lubricate the Mortise
A light application of graphite or a PTFE-based lubricant on the mortise keeps the mechanism smooth. Avoid heavy oils that attract dust.
