How to Troubleshoot a Schlage Keypad Lock that Unlocks Without Code?

Here are some troubleshooting steps to try if your Schlage Keypad Lock unlocks without code:

1. Check and Set the Lock to Unlocked

Some Schlage keypad lock models (like the Schlage FE595), come with the Re-lock and Unlocked mode. When set to “unlocked”, the lock will unlock when you press the Schlage button (without entering a User Code). And when it’s set to “re-lock”, the lock returns to normal, meaning you’ll need to enter a valid code to unlock it.

If your Schlage lock unlocks without entering a code, there’s a good chance that it’s in “unlocked” mode.

Here’s how to know whether your lock is set to “unlocked” or “relock”:

Check the inside thumb turn—it should be in a vertical or horizontal position. If it’s in a vertical position, it means the lock is set to “unlocked”. And if it’s in a horizontal position, it means the lock is set to “re-lock”. See the image below.

So if your lock’s interior thumb turn is set in the vertical position, simply rotate it to the horizontal position to fix the “unlocking without code” issue.

If this doesn’t help, continue to the next step.

2. Change the Batteries

Your Schlage keypad lock may malfunction if the batteries are low. More so, if you’ve used the wrong batteries (lithium batteries), the lock may start acting weird, especially when batteries are getting low. This is common with lithium batteries.

Replace the batteries in your lock with a fresh set of alkaline batteries. Note that lithium batteries are not recommended for Schlage locks.

Next, try to lock and unlock your door to see if the problem is fixed.

Continue to the next step if the issue persists.

3. Perform a Reset

Unseen glitches/incorrect settings can also cause this issue. If the above fixes fail, the next thing you want to do is reset the lock. This usually helps to rid some minor glitches and correct incorrect settings.

Follow the steps below to reset your lock:

  • Remove the battery cover and disconnect the battery.
  • Press and release the outside Schlage button.
  • Reconnect the battery, then press and hold the outside Schlage button until it illuminates green, followed by one long beep. Make sure to complete this last step within 10 seconds.

And that’s all you need to do to reset your Schlage lock (BE365, BE375, FE575, etc.).

Note that resetting your lock will delete all your previous programming, so you’ll need to start all over again to program it. Be sure you have your default Programming Code to hand as you’ll need it to reprogram the lock. See how to find your Schlage lock default Programming Code.

4. Reinstall the Lock

If your lock still unlocks without a code after the above fix, then there’s a good chance that the lock wasn’t installed correctly. Uninstall the lock and install it again—make sure the cam and bolt positions are correct.

More so, ensure you install the lock following the handing of your door—right-handed or left-handed door.

For the installation guide, check the user manual or google your Schlage lock model to find specific installation instructions. You may also consider getting an expert to help you.

Wrapping Up

As mentioned, there may be several reasons behind the issue with your Schlage lock (unlocking without a code).

To fix this, switch the lock to the unlock position. And if that doesn’t work, replace the batteries, perform a reset and reinstall the lock.

This should fix the issue. But if everything fails, contact Schlage Customer Support for help.
