Schlage Lock Not Working After Battery Change: How to Fix the Problem
Table of Contents
So if your Schlage keypad lock stops working after replacing the batteries, here’s how to go about it:
1. Ensure You’re Using the Right Batteries
All Schlage electronic/smart locks are powered by alkaline batteries (non-rechargeable), and that’s what Schlage recommends.
While lithium or other types of rechargeable batteries may work, you may experience undesirable operation—just like what you are probably experiencing. So if you’ve replaced your Schlage lock batteries with lithium batteries and the like, you need to change them and get alkaline batteries to avoid unsatisfactory operation.
Also, ensure you replace all batteries for the best performance. That is, do not mix old batteries with new ones, as that may cause your lock to stop working.
And depending on your Schlage lock model, you want to ensure you’re using the appropriate batteries. The table below shows the different Schlage electronic lock models and the type/number of batteries required.
| Lock | Required Batteries |
| Schlage Sense Smart Deadbolt, Schlage Connect Smart Deadbolt, and Schlage Encode Smart Wi-Fi Deadbolt. | 4 x AA batteries (see recommended batteries). |
| All Schlage Keypad locks and Schlage Touch locks. | 1 x 9-volt battery (see recommended batteries). |
| Schlage Locks with Built-In Alarm. | 2 x AAA batteries (see recommended batteries). |
2. Check that the Battery Connector is Intact
Assuming you’re certain that your Schlage lock has the right batteries but still not working, then you want to check if the battery connector is still intact.
Sometimes, during battery change, the battery connector may be disconnected in error, and your lock won’t work (electronically) without the battery connector properly connected.
So check that the battery connector is intact. If not, get it connected and then try to operate your lock again—to see if it works.
3. Reset Factory Settings
If steps 1 and 2 couldn’t fix the problem, then try to factory reset the lock. Factory resetting will erase all settings, thus correcting any wrong electronic configuration in the lock. And this might get your lock up and running again—if you ticked the boxes in steps 1 and 2.
So here’s how to factory reset your Schlage lock:
- Step 1: Slide the battery cover up to remove it.
- Step 2: Remove the battery connector and then press and hold the Schlage Button on the keypad.
- Step 3: While still holding the Schlage Button, reconnect the battery connector.
Now that’s all about resetting your Schlage lock. The green check on the keypad and the Schlage button will flash three times each—indicating the process was successful.
Note: All stored user codes and programming code will be erased after restoring factory settings. So you’ll have to reprogram your lock using the default programming code and ensure you change the code for security reasons. See how to add user codes and change the preset programming code on a Schlage lock.
Also, if you have previously enabled auto-lock, low battery notification alert, and the like, make sure to re-enable them as they’ll all return to default settings after restoring factory settings.
That said, if your lock doesn’t work after all, then you may have to contact Schlage or get a locksmith to assist you further.
Wrapping Up
If your Schlage lock was working properly but eventually stopped after changing batteries, then it’s safe to assume that the problem is connected to the battery replacement. Perhaps you got substandard or inappropriate batteries.
So while you may be able to fix the problem with the above tips, ensure you get premium unused alkaline batteries. You may also want to confirm that the batteries are active before using them on your lock.
