Lockly Smart Lock Battery Flat, Forgot Password or Won't Open?

The short answer: If the batteries die completely, hold a 9V battery against the contact points on the 9V backup socket at the bottom of the outside unit until the door unlocks. The lock detects polarity automatically. Replace the main batteries straight after. If that doesn't work, call or WhatsApp 9224 9224, any time.

Lockly smart lock battery flat? How to open it from outside

If the batteries die completely, hold a 9V battery against the contact points on the 9V backup socket at the bottom of the outside unit until the door unlocks. The lock detects polarity automatically. Replace the main batteries straight after.

The Secure Pro takes four AA alkaline batteries, lasting up to a year. When they're low, a battery icon lights up; it can still run up to 300 cycles in low-battery mode.

How to change the password on a Lockly smart lock

Codes are added and deleted in Programming Mode (battery cover off, press the Program button), or in the Lockly app once paired. A code is changed by deleting the old one and adding a new one.

How to reset a Lockly smart lock

The Reset button is on the inside back panel, next to the Program button. Have the Activation Code card ready. A reset deletes all stored data.

Three wrong codes within 5 minutes put the lock into Safe Mode: the keypad locks for 10 minutes, then 20, then 30. Enter the correct code twice, use a fingerprint, the app or the key to clear it.

Lockly smart lock not working? Common problems

Your Lockly lock	Likely cause	What to do
Keypad completely dark	Batteries flat	From outside, hold a 9V battery to the backup contacts at the bottom of the outside unit. Then replace the batteries from inside.
Accepts the code but the latch won't turn	Weak batteries, or a mechanical fault in the lock body	Try emergency power once. Don't force the handle: that's how lock bodies break.
Refuses a code you know is right	Privacy mode set from inside, or the wrong-code lockout	Three wrong codes within 5 minutes put the lock into Safe Mode: the keypad locks for 10 minutes, then 20, then 30.
App shows offline or can't connect	Wi-Fi, hub or Bluetooth	Use the keypad or fingerprint at the door: the Lockly lock works without the app.

With PIN Genie on, the digits move every time. Look for your digit on any button and press it; you don't press a fixed position.

A typical Lockly call

This is the kind of Lockly call we often get: A guest tries the wrong code on a Lockly lock three times and Safe Mode locks the keypad for 10 minutes, then 20 after another try. The owner is overseas. If the owner can't unlock it from the app, we're called.

What's different about Lockly locks

Lockly's PIN Genie keypad scrambles the digits each time, and its Safe Mode lockout gets longer with each failed attempt: 10, 20, then 30 minutes.

Tips for Lockly owners

• Keep your Activation Code card somewhere safe: you need it to reset.
• Carry a key, as Lockly recommends, in case Safe Mode kicks in.
• Keep a 9V battery handy for emergencies.
• Leave PIN Genie on for privacy.
