Schlage Lock Broken Wire? How To Diagnose And Repair It
I fixed my Schlage Encode Plus smart lock broken wire with very little effort, and you can too. When my smart lock suddenly stopped working, I feared the worst. It wouldn’t power on after a reset attempt, and I discovered a broken wire at the battery connector. At first, I thought I might have to replace the entire lock—a cost of $250 or more. But with a $5 replacement part and some basic tools, I was able to repair it myself. Here’s exactly what I did so you can do it too.
What Happened
While trying to perform a factory reset on my Schlage Encode Plus (model BE499WBCAM619), I had to remove the lock from the door to view the programming passcode and initial entry codes. During that process, the black battery wire became detached from the connector.
Without that connection, the lock had no power and wouldn’t respond at all. I thought I would have to replace the entire lock.
The $5 Fix for My Schlage Lock Broken Wire
Instead of giving up, I ordered a replacement 9V battery clip online for just a few dollars. It came with red and black wires that I could splice directly into the lock’s wiring harness.
Since space is limited inside the lock and I had no room for twist cap connectors, I performed the following steps for the repair:
- Disconnect the battery clip from the battery case
- Cut both the black and red wires attached to the lock and the new clip’s wires so that their total length would be long enough to twist them together and the resulting wire would be about the same length as the original one (longer is better, as you can always shorten them if needed)
- Stripped the ends of all the wires about 1/2 inch to give room to twist them together securely
- Twisted the black wires together tightly and then twisted the red wires together tightly
- Secured the black wire connections with electrical tape and then secured the red wire connections with electrical tape in the same way
- Tucked the taped wire neatly inside to avoid obstruction
Once everything was connected and reassembled, the lock powered on immediately.
Before You Start
If your smart lock isn’t responding, check the basics first:
- Try a fresh set of batteries
- Make sure the battery pack is properly connected
- Look for loose or broken wires under the interior cover
- Find your lock’s model number to follow the correct reset steps
Also, be sure to work with the door open and unlocked during the reset process, just in case the lock motor activates.
Resetting the Schlage Lock after Repairing the Broken Wire
With the battery connector fixed, I was able to complete the factory reset:
- Disconnect the battery pack
- Press and hold the Schlage button on the outside keypad a few times
- Reconnect the battery pack while holding the button
- Hold until the green check mark lights up, then release
This reset tutorial video helped me visualize the process step-by-step, especially since we bought our home secondhand and didn’t receive any lock documentation.
Reprogramming the Code
Using the default programming code found behind the inside lock mechanism, I added a new entry code manually using the Schlage keypad. No app required.
This video on programming the lock walked me through the process clearly.
What to Do If You Don’t Have the Programming Code
If you don’t have the default programming code (common when buying a house with the lock already installed), you’ll need to:
- Remove the interior battery cover
- Look for a label with two 4-digit user codes and a 6-digit programming code
- If it’s missing, a full factory reset may still allow you to set up the lock again through the Schlage Home app, depending on the model

- Schlage Customer Support for guidance
- A local locksmith familiar with smart locks

FAQ
What causes a Schlage smart lock to stop working?
The most common reasons include dead or improperly installed batteries, a loose battery connector, or a broken wire. If you’ve changed batteries and the lock still won’t power on, it’s worth checking inside the cover for damage to the wiring.
Can I fix a Schlage smart lock myself?
Yes! Many issues—like a broken battery wire—can be fixed with basic tools and inexpensive parts. You don’t need to replace the entire lock.
Will repairing the wire void my warranty?
Possibly. If your lock is still under warranty, contact Schlage support first. But if it’s older or out of warranty, a DIY repair can be a practical and budget-friendly option.
Does this fix apply to all Schlage locks?
This tutorial is specific to the Schlage Encode Plus model (BE499WBCAM619), but the wiring and reset process may be similar in other models. Always check your model number and documentation.
Can I still use the Schlage app after a manual reset?
Yes. After a factory reset, you can reconnect the lock to the Schlage Home app or Apple HomeKit, depending on your preferences. Just follow the in-app setup steps.
Encouragement for Other DIYers
If your Schlage smart lock isn’t powering on and you’ve already tried new batteries, take a look under the hood. It might be something as fixable as a loose or broken wire. You don’t have to be an expert electrician—just patient, careful, and a little determined.
Give It a Try: This repair took me less than 30 minutes and saved me over $250. If you’re facing a similar issue, I hope this guide gives you the confidence to try the repair yourself. You might surprise yourself with what you can fix.
