At Family Garage Door Repair of Charlotte, we understand the importance of having a reliable, secure, and easy-to-use remote for your garage door system. One of the most popular and trusted remote controls today is the LiftMaster 373LM 3-Button Remote Control. Whether replacing a lost remote, upgrading your system, or needing help programming your current one, our team is here to assist you every step of the way.
What is the LiftMaster 373LM Remote?
The LiftMaster 373LM is a 3-button garage door opener remote that controls up to three garage doors, gates, or compatible LiftMaster accessories. It operates on the 315 MHz frequency and features Security+ rolling code technology, which changes the access code each time the remote is used. This helps protect against code-grabbing and unauthorized entry, giving homeowners peace of mind.
Features and Benefits
Three-button functionality: A single remote can control up to three garage doors or gate operators. It’s ideal for homes with multiple doors or families with shared access needs.
Enhanced Security with Security+ Technology: The 373LM utilizes LiftMaster’s rolling code system, which generates a new security code each time you press the button. This feature prevents replay attacks and adds a critical layer of protection.
Compact and Convenient Design: This remote is small enough to clip to your car visor or fit comfortably in your pocket or bag using the included clip.
LED Indicator: A bright LED light lets you know when the signal is being sent—useful for programming and troubleshooting.
Battery Included: Comes pre-installed with a long-lasting 3V lithium coin-cell battery, ready to use out of the box.
Compatibility
The LiftMaster 373LM remote is compatible with LiftMaster, Chamberlain, Craftsman, and Raynor garage door openers manufactured between 2006 and 2014, specifically those equipped with a purple “Learn” button on the back of the motor head.
Tip: If your garage door opener’s Learn button is purple, the 373LM remote is the right match for you.
Programming the 373LM Remote
Programming the 373LM is simple:
Locate the purple “Learn” button on the garage door opener.
Press and release the Learn button (the indicator light will turn on).
Within 30 seconds, press and hold the desired button on your 373LM remote until the garage door opener lights flash or you hear two clicks.
If you’re not comfortable programming the remote yourself, Family Garage Door Repair of Charlotte can help. Our technicians will arrive with the proper tools and knowledge to ensure your system is programmed correctly and functioning safely.
Common Use Cases
Replacing a Lost Remote: If you’ve lost your old LiftMaster remote, the 373LM is an excellent replacement.
Upgrading for Multiple Door Control: If your current remote only controls one door and you have more than one, the 373LM allows convenient operation of all doors from a single device.
Gated Communities or Secondary Residences: It is excellent for use in homes with a main garage and a gate or properties with multiple LiftMaster systems.
