Programming the 387LM: Initial PIN Setup
Setting up the LiftMaster 387LM Universal Wireless Keypad for the first time involves programming your initial PIN. Before you begin, make sure your garage door is closed. Start by locating the Smart/Learn button on your garage door opener motor unit or external receiver; consult your owner’s manual if needed.
To begin programming, press and hold the * and # buttons on the keypad simultaneously until the keypad lights turn on. Next, enter your desired 4-digit PIN, followed by pressing the # button. Then, locate the Learn button on your garage door opener and press it. Within 30 seconds, enter your PIN on the keypad again, followed by the # button. The garage door should now activate, indicating successful programming.
If the garage door does not activate, repeat the process. Ensure that you are within range of the garage door opener and that the keypad is compatible with your opener’s frequency. Some openers may require you to enter a brand ID number after your PIN; refer to the compatibility chart in the instructions for the correct ID. Always test the keypad after programming to ensure it correctly operates the garage door. With these steps, you can easily set up your 387LM keypad for secure and convenient access.
Changing an Existing PIN
Updating your PIN on the LiftMaster 387LM Universal Wireless Keypad is a straightforward process that enhances security. Begin by ensuring your garage door is closed. Access the keypad and press and hold the * and # buttons together until the keypad lights illuminate, indicating it’s in programming mode. Next, enter your existing 4-digit PIN, followed by pressing the # button. The keypad should acknowledge your current PIN.
Now, enter your desired new 4-digit PIN, followed by pressing the # button again. The keypad will prompt you to re-enter the new PIN for confirmation. Enter the new PIN once more, followed by the # button. If the process is successful, the keypad lights will flash, confirming that your PIN has been updated. Test the new PIN immediately to ensure it operates the garage door correctly.
If the PIN change is unsuccessful, repeat the process, making sure to enter the correct existing PIN and the new PIN accurately each time. If issues persist, consult the manual for troubleshooting tips or consider resetting the keypad to its factory defaults and starting the programming process from scratch. Regularly changing your PIN is a good security practice to prevent unauthorized access to your garage.
Troubleshooting Common Issues
Encountering issues with your LiftMaster 387LM keypad can be frustrating, but most problems have simple solutions. One common issue is the keypad not responding.
