The sticker on the back of your Schlage keypad is a security hole

What this error means

Documented and underappreciated: Schlage keypad locks ship with their default programming and user codes printed on a sticker on the back of the exterior keypad assembly — readable by anyone who removes two screws. And a factory reset restores those printed defaults. Translation for offices: if your suite's keypad still uses the codes it shipped with, or the lock was ever factory-reset without reprogramming, the 'secure' door is running on codes physically printed on the device.

Symptoms

• Office moved in and kept the previous tenant's codes
• Nobody knows the programming code
• Lock was reset during troubleshooting

Try this first (safe DIY steps)

1. Change the programming code today (Schlage publishes the procedure per model — takes two minutes)
2. Change/audit user codes: one code per person or team, deleted at offboarding
3. Don't remove the sticker (Schlage advises keeping it — it's your recovery path after a reset), but treat physical access to the keypad screws as equivalent to a key
4. Calendar a code audit alongside your other quarterly checks

Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.

When to call a technician

If codes are unknown and the programming code is lost, factory reset + full reprogram from the sticker defaults — DIY per the manual, or a locksmith visit ($107–$242 typical).
