When it comes to home security, your garage is one of the most important access points to protect. Many homeowners with automatic garage door systems have questions about the safety features of their openers—especially those made by Chamberlain, a leading brand in the industry. A commonly asked question is: “Does my Chamberlain garage door opener have a rolling code?”
Understanding whether your opener uses rolling code technology is crucial for ensuring your garage door is secure from unauthorized access. This guide will walk you through everything you need to know about Chamberlain’s rolling code systems, how to check if your model has it, and what to do if it doesn’t.

What Is a Rolling Code and Why Is It Important?
Before we dive into the details of your Chamberlain garage door opener, let’s clarify what a rolling code is and why it matters.
Rolling code technology (also known as hopping code) is a security feature used in garage door openers and other remote control systems. Instead of using a fixed code that can be intercepted and cloned by criminals, rolling code systems generate a new code each time the remote is used. This drastically reduces the chance of code grabbing or replay attacks.
The technology works using encryption algorithms between the transmitter (remote control) and the receiver (garage opener). Both devices stay in sync with one another and “roll” to the next code in a predetermined sequence after every use.
This method is widely regarded as one of the most effective ways to secure wireless garage entry systems.
Does My Chamberlain Garage Door Opener Have A Rolling Code?
Let’s get straight to the core question: Does my Chamberlain garage door opener have a rolling code?
The Short Answer:
Most modern Chamberlain garage door openers manufactured after 1993 do include rolling code technology, particularly those with Security+ or Security+ 2.0 branding.
But if you’re unsure about your specific model, the following sections will help you determine it step-by-step.
How to Identify If Your Chamberlain Garage Door Opener Uses Rolling Code
There are a few simple ways to confirm whether your garage door opener includes rolling code functionality:
1. Check the Learn Button Color
Chamberlain garage door openers come with a “Learn” or “Smart” button used for programming remotes. The color of this button often indicates the type of security system your opener uses:
- Yellow button: Security+ 2.0 (uses rolling code)
- Purple button: Security+ (uses rolling code)
- Red/orange button: Security+ (uses rolling code)
- Green button: Usually does not have rolling code (older systems)
If your unit has a yellow, purple, or red/orange Learn button, your Chamberlain opener most likely supports rolling code technology.
2. Check Your Remote’s Branding
If your remote or wall console features the words Security+ or Security+ 2.0, it’s using rolling code encryption.
Security+ 2.0 is an upgraded version of the original Security+ and includes additional features like interference resistance and multiple device syncing.
3. Look at the Model Year
Chamberlain began introducing rolling code systems in 1993. If your garage door opener was manufactured before 1993, it likely does not have a rolling code system.
To find out your opener’s manufacturing date, look for a label on the back or side of the motor housing. It should include a model number and date of production.
4. Refer to the User Manual
The quickest and most accurate way to confirm rolling code support is to check the user manual for your opener. If you’ve lost your manual, you can find one online by searching your model number on Chamberlain’s website.
Why Rolling Code Technology Matters for Garage Security
Rolling code technology provides peace of mind by eliminating one of the biggest vulnerabilities in remote access systems: code grabbing.
Without rolling code, anyone using a simple radio frequency scanner could intercept the signal from your remote and replay it later to gain access to your garage.
With rolling code in place, the signal changes every time, rendering the previous code useless—even if someone has captured it.
This is particularly important for:
- Detached garages that may not have other forms of entry protection.
- Smart home systems where multiple access points are integrated.
- High-theft areas, where garage break-ins are common.
What If My Chamberlain Opener Doesn’t Have a Rolling Code?
If you discover that your Chamberlain garage door opener does not use rolling code technology, you have several options to upgrade your system’s security.
Option 1: Add a Security+ 2.0 Receiver
You can purchase and install a universal rolling code receiver that connects to your older opener. Chamberlain and LiftMaster both offer aftermarket solutions that can add rolling code compatibility to older models.
Option 2: Upgrade to a Newer Chamberlain Opener
If your opener is very old or lacks other modern safety features, consider upgrading entirely. Newer Chamberlain models come with built-in Wi-Fi, MyQ smart control, motion-sensing lights, and rolling code security.
Models like the Chamberlain B970 and B1381 feature ultra-quiet operation and maximum security protocols.
Option 3: Use a Smart Garage Hub
Chamberlain’s MyQ Smart Garage Hub allows you to control your garage door opener using your smartphone, regardless of whether it has rolling code tech. While the MyQ hub itself doesn’t add rolling code security to older openers, it gives you additional control and monitoring features.
Pros and Cons of Rolling Code Technology
Let’s break down the benefits and potential downsides of rolling code garage openers.
✅ Pros:
- Strong protection against hacking and code stealing
- Auto-synchronization between remote and opener
- Trusted and widely used by leading manufacturers
- Enhances overall garage and home security
❌ Cons:
- Slightly more complex programming
- Not compatible with some third-party remotes
- Can become desynchronized (though rare)
Frequently Asked Questions
Q: Can I tell if my remote uses rolling code by looking at it?
Yes. Look for Security+ or Security+ 2.0 labels on the remote. You can also check the FCC ID and compare it to lists of rolling code remotes online.
Q: Will a universal remote work with rolling code Chamberlain openers?
Only if the universal remote supports rolling code systems. Make sure to check compatibility before buying.
Q: Can someone still hack into my garage if I have a rolling code opener?
While no system is 100% secure, rolling code significantly reduces the risk compared to fixed-code systems.
Does My Chamberlain Garage Door Opener Have A Rolling Code? Final Thoughts
In summary, most Chamberlain garage door openers manufactured after 1993 include rolling code technology, especially those labeled with Security+ or Security+ 2.0. The easiest ways to determine this are by checking the Learn button color, looking at your remote, reviewing your manual, or noting the manufacturing year.
If your system lacks this important feature, you can still enhance your garage’s security through add-on receivers or by upgrading to a newer model.
Your home’s safety is worth the effort of checking.
