Chamberlain CH382 Keychain Remote: Features, Compatibility, and Setup Guide

When it comes to convenience and security for your garage, the Chamberlain CH382 2-Button Keychain Remote is a compact yet powerful tool designed to simplify everyday access. Whether you need a spare remote, an upgrade from an older model, or the ability to control multiple doors, this small device delivers reliability, portability, and peace of mind.

Wide Compatibility

The CH382 is engineered for use with all Chamberlain®, LiftMaster®, and most Craftsman® garage door openers manufactured after 1997, with the exception of Craftsman Series 100 models. Thanks to rolling-code technology, the remote works securely with modern systems, ensuring protection against unauthorized access.

Each of the two buttons can be programmed independently, giving you the flexibility to control two different garage doors or gates with a single remote. This makes it a great choice for families with multiple garages or a garage and gated entry.

Simple Programming Options

Setting up the CH382 is a quick and straightforward process. The remote syncs using your garage door opener’s Learn button, which may be yellow, purple, red, orange, or white. Depending on the color, the programming steps vary slightly, but all are designed for easy setup in just a few minutes.

For openers equipped with myQ technology, you can even use the myQ app to program your remote. This unlocks advanced features, such as naming your remote, viewing access history, and receiving notifications when the remote is used.

Built for Safety and Security

Safety is a top priority with Chamberlain remotes. The CH382 utilizes rolling-code encryption, which generates a new code each time the button is pressed, thereby helping to prevent code grabbing or signal theft.

The manual also emphasizes responsible use: keep remotes out of the reach of children, never activate a garage door without a clear view, and ensure the door remains in sight until it is completely closed.

Long-Lasting Power

The CH382 operates on a 3V CR2032 coin-cell battery designed for long-term reliability. When replacement is needed, the process is quick and simple:

1. Separate the top and bottom housing with a small screwdriver.

2. Slide out the old battery following the direction arrows on the circuit board.

3. Insert the new CR2032 battery with the positive side facing up.

4. Snap the housing back together until it clicks securely.

This ensures you can keep your remote functioning smoothly without costly replacements.

Warranty and Support

The CH382 comes with a one-year limited warranty, protecting against defects in materials or workmanship. Chamberlain also offers replacement parts, such as visor clips, and provides additional help through its customer support site and manuals.
