How To Open A Schlage Lock With A Dead Battery

If you have been overlooking your Schlage lock’s status light warnings, you are at risk of being locked out of your house. In that scenario, you may unlock your deadbolt using a physical key. However, in the absence of a key, try jump-starting your deadbolt using a 9V battery to open your door lock or pick your lock using a lock-picking kit, bobby pin, or a paperclip.

Here’s how it works:

  • Step 1: Locate the contact points on your Schlage lock. The points can be found below the touchscreen in most Schlage lock models.
  • Step 2: Take a good quality 9V battery and match it with the contact points correctly until the lock beeps thrice and you see the indicator light flash red and green. 

    It is noteworthy that a normal 1.5V battery will not jumpstart your lock, so ensure to use a 9V battery only.
  • Step 3: Once you hear the sound and see the light, the Schlage lock will jumpstart. Now, enter the user code (primary or guest) to unlock your Schlage lock to gain access to your place.

You must note that you can unlock the lock using the jumpstart method, but the Schlage lock cannot be locked again for regular use until the lock batteries are replaced.

The jump start troubleshoot works great to unlock a Schlage lock with dead batteries and has been tried and tested by me a number of times. The alternative could be picking your lock using a bobby pin, paperclip, or lock-picking kit. You may read the detailed steps for the same in one of my past articles.
