Schlage Smart Lock 5 Red Flashes — Programming Error

What Does This Error Mean?

5 red flashes on a Schlage Encode/Connect indicates a programming error — the sequence you tried to enter wasn't recognized.
Either the master code was wrong, the timing was off, or the button sequence wasn't correct.
Wait for the lock to time out (about 10 seconds), then retry the programming sequence carefully.
Use the app instead of keypad programming if keypad programming keeps failing.

Affected Models

Schlage Encode
Schlage Encode Plus
Schlage Connect
Schlage Sense

Common Causes

Wrong master code entered during programming
Pressed wrong button in the programming sequence
Took too long between button presses
Didn't press Schlage button to start programming
Lock not in programming mode despite attempt

How to Fix It

Wait 10 seconds for timeout.

When 5 red flashes appear, the lock is in error state.
Wait 10 seconds without pressing anything.
The lock returns to standby.
You can then start the programming sequence fresh.
Read your model's programming sequence.

Schlage Encode and Schlage Connect have different sequences.
Open the user manual or Schlage's online support.
Common sequence: press Schlage button (the brand logo) → enter master code → enter user slot → enter new code → press Schlage button to confirm.
Have everything written down before starting.
Verify your master code.

If you can't enter the lock with the master code (using it as an unlock code), it's wrong or has been changed.
Test by entering master code and pressing Schlage button — should unlock.
If it doesn't, you've forgotten the master code.
Factory reset is required (loses all programmed codes).
Use the Schlage Home app instead.

Schlage Encode connects to the Schlage Home app.
Programming through the app is much easier than keypad — no timeouts, clear instructions, no risk of 5 red flashes.
If you're having trouble with keypad programming, switch to app programming.
Factory reset if master code is lost.

If you've forgotten the master code completely, factory reset is the only path.
Procedure: remove battery cover, remove batteries, hold the Schlage button while reinserting batteries, follow setup procedure to set new master.
This loses all programmed user codes.

Frequently Asked Questions

What's the master code default?

Schlage default master codes are printed on a sticker inside the battery compartment when the lock is new.
If you've never changed it, look there.
If you've changed it but forgotten the new one, factory reset is the only option.
Always note the master code somewhere safe.

Can 5 red flashes mean something else?

Schlage uses 5 red flashes specifically for programming errors.
Other flash patterns mean different things: 1 flash + 3 beeps (wrong code), 3 flashes (lockout), rapid flashing (low battery).
Each pattern has a specific meaning — consult your Schlage manual to interpret.
