Schlage Lock Blinking Red? (Possible Causes & Fixes)

Schlage locks are a great security product for both residential and commercial use, but they have the occasional hiccup that results in red blinking. Learning what causes this is the first step in finding a solution

There are two red blink codes for a Schlage lock- steady blinks or red blinking followed by green, with sound. If your Schlage lock exhibits constant blinking, it’s because the battery is almost dead, and the keypad won’t work. If your lock is blinking red, then green with high/low beeps, the batteries need to be changed soon.

Follow along to discover why your Schlage lock is blinking red, what each blink code means, and how to fix your keypad!

Why Is My Schlage Lock Blinking Red?

A Schlage lock is an excellent home or business investment; however, sometimes, it begins to blink red. How should you proceed?

A red blinking Schlage Lock means one thing- an issue with your batteries. However, how the light blinks will tell you exactly what’s wrong.

We’ll dive into the details regarding blink patterns and what each one means below!

Why Is My Schlage Lock Blinking Red After I Type in the Code?

Any type of error code causes the user to wonder, “What did I do wrong?” In the case of red light blinking after entering a Schlage lock code- the answer is nothing.

How the story goes is when you type in your user code, the Schlage lock will blink red while releasing high and low noises. Then, it will blink green a few times after a slight pause, and the keypad will open the door. This sequence indicates that your lock batteries are low and need to be changed soon.

If you don’t take care of this soon, your lock will no longer work. Then, you will be forced to use a key. Goodbye, keyless entry; it was fun while it lasted.

Why Does My Schlage Lock Have a Steady Red Blink?

There’s also another scenario that could occur. That is when your Schlage lock has a steady red blink, without you typing in a code or touching it at all.

When this happens, you’re in the danger zone. A steady blinking red light indicates that the battery is critically low and should be replaced as soon as possible.

You have now reached the point where the keypad is no longer functioning, and you must use a key to get inside. This is generally where we blame the customer. You should have listened to the warning signs!

Fret not! There is a very simple solution. We’ll walk you through how to change the batteries below so you can be on your merry (and keyless) way!

How Do You Change the Batteries in a Schlage Lock?

To complete this task, all you need is a screwdriver and your new battery.

Most Schlage locks take one 9-volt alkaline battery. To replace it:

Step 1: Remove the two mounting screws on the inside portion of the lock.

Step 2: Take the cover off and set it aside.

Step 3: Detach the old battery, and replace it with a new one.

Step 4: Tuck the wiring into place and put the cover back on using the two screws you initially removed.

Once you are finished, the red blinking should cease, and you will be able to use your keypad for entry/exit once again. If the blinking persists- something went wrong.

Why Is My Schlage Lock Still Blinking After a Battery Change?

If your Schlage lock is still blinking red even after you’ve swapped out the batteries, there are a few reasons.

  • The batteries were inserted incorrectly.
  • The wrong batteries were used.

Reason #1: The Batteries Were Inserted Incorrectly

Inserting batteries incorrectly happens more often than you might think.

While most Schlage locks require one 9-volt alkaline, some take 4 AA batteries, and others use 2 AAA batteries. Regardless of which one you’re replacing, they must be inserted correctly.

If you’re using a single 9-volt alkaline battery, make sure the wires are hooked up to the positive side. For AA or AAA batteries, make sure the positive side (the copper-colored side for Duracell batteries) faces AWAY from the spring.

Therefore, the negative side will be touching the spring.

Reason #2: The Wrong Batteries Were Used

Using the correct batteries is just as essential as putting them in the right way.

The best batteries to use for a Schlage lock are alkaline, non-rechargeable batteries. You can opt for any brand; however, you may not get your money’s worth if you use a different type (for example, lithium).

No one wants to have to keep changing out the batteries more often than necessary.

When It’s Time to Call Customer Service

If your batteries are in place, you’re using the right ones, and they’re new, but you STILL have a blinking red Schlage lock, time to call in the big dogs.

And by big dogs, I mean Schlage customer support. Sometimes, no matter what you do, the system has a glitch that can’t be solved at home.

The Bottom Line

Schlage locks are designed to notify you of problems, so it’s important that you understand what causes each warning code before taking action!

There are two types of Schlage lock red blinks: A steady red light or a flashing red, then green light after inputting a code. The first is indicative of low batteries that will need replacing soon.

The second sequence is caused by dangerously low battery power, which will require immediate replacement as your keypad is no longer functional.

If there is still power left on the batteries, then most likely, an error has occurred due to improper installation or using the wrong type of batteries.

When you’ve tried everything and still can’t stop your Schlage lock from blinking red, contact customer support. You should also check your warranty plan to see if your device is covered!
