Schlage Keypad Lock Won’t Lock? (How To Troubleshoot)

It can be ridiculously frustrating when your Schlage keypad lock refuses to lock correctly. I’m going to walk you through some of the most common reasons a Schlage keypad lock might fail to lock and give you some solutions based on my experience.

Let’s begin without wasting much time!

Troubleshooting A Schlage Keypad Lock That Won’t Lock

Troubleshooting a Schlage keypad lock that won’t lock is something I’ve done quite a few times but it’s always tough when there are a lot of different issues. Each issue has to be eliminated and then when you’re left with no issues, your door will lock correctly. The following will cover common suggestions of what you may need to change in order to solve your problem.

1. Replace Batteries

Many electronic locks are powered by batteries, and batteries can lose their charge over time. If your lock won’t lock or unlock, first check that you have fresh batteries installed. The Schlage keypad lock requires four AA batteries to function. If the indicator light on the keypad is blinking, this means you’ve got a power problem and should swap out the batteries.

Therefore, replace the old batteries with new ones and then retry locking the door. This time it should work. If not, continue towards the next step.

2. Check Whether Your Lock Is Set To Unlocked (Schlage FE595 Only)

The Schlage FE595 keypad lock has a special setting that allows you to always keep your door unlocked? Sure, it might not be the safest feature (we don’t recommend using it), but it’s great for when you have people coming and going from your home throughout the day. The only problem is that sometimes, people forget to switch back to locked mode at night. So, if you can’t figure out why your Schlage keypad lock is not locking, the first thing you should check is whether your lock is set to “unlocked.”

To check on this, insert a Schlage key into the keyhole. Then, twist the key clockwise (to right) as far as it will go and hold it there. While holding the key in place, enter your code on the keypad. If you feel a resistance while entering your code, then your lock is set to “unlocked.” Simply twist the key counterclockwise (to left) until you hear one beep. The lock should now be set to “locked,” and it should lock when you press any button or close your door.

3. Ensure You’re Locking The Lock Correctly

When you have a Schlage keypad door lock that’s not locking, the first thing to do is make sure you’re locking it correctly.

 If you’ve been using the key for a while, you might be putting it in upside down and accidentally locking it that way. The first thing to do is make sure your eyes aren’t playing tricks on you. Hold the lock horizontally and turn it over to examine both sides of the keyhole. You should see a vertical slit with a horizontal slit in it on the side that says “Schlage” on it. This is the correct side to insert your key into and turn counterclockwise until you hear a click.

If you are indeed inserting the key correctly, then something else must be wrong with your lock.

4. Reset The Lock

If your Schlage keypad lock won’t lock, it could be because of a programming error. To fix this problem, you can reset the lock by following the below mentioned steps.

  1. Remove the battery pack from the back of the lock and press and hold the button for 15 seconds.
  2. Reinstall the battery pack.
  3. Enter your unique six-digit programming code (or 40-bit keycode) and press the Schlage button.
  4. The Schlage button will flash green, indicating that you’ve successfully reset your lock.

Continue to the next troubleshooting step if the issue persists.

5. Lock It with A Physical Key

The final troubleshooting step that you can follow is to lock it with a physical key. If that works, you might have a problem with the touchscreen or the battery. However, if you can’t lock the door with a physical key, it could mean something is broken or jammed in the deadbolt’s mechanics. At this point, we recommend contacting Schlage customer service or a professional locksmith to take a closer look at your lock.


As previously stated, your Schlage keypad lock may refuse to lock for a variety of reasons. You are requested to attempt all of the troubleshooting methods to determine which one resolves the problem.

That’s all there is to it! I hope this post was helpful and that you were able to resolve the “not locking” problem with your Schlage keypad lock.
