Operating Instructions
1. Programming Your Personal Identification Number (PIN)
To program your keypad, you will need to access the "LEARN" button on your garage door opener. The programming steps are typically found on a label under the keypad's flip-up cover.
- Locate and press the "LEARN" button on the rear control panel of your garage door opener. The LED light on the opener will illuminate, indicating it is in learn mode.
- Within 30 seconds, enter your desired 1 to 6 digit PIN code on the keypad.
- Press the "ENTER" key on the keypad. The opener's light will flash once or twice, and the unit will beep, confirming that the PIN has been successfully stored in memory.
- Test the new PIN by entering it and pressing "ENTER". Your garage door should activate.

3. Stopping or Reversing Door Movement
Similar to a remote control, if the garage door is in motion after activation, you can stop its movement by pressing the "ENTER" key again within 30 seconds. Pressing "ENTER" a third time within the same timeframe can reverse the door's direction.
4. Erasing PIN Codes
To erase existing PIN codes from the keypad, you must clear the memory of your garage door opener. Refer to your garage door opener's manual for specific instructions on how to clear its memory. After clearing, all remote controls and PIN codes will need to be reprogrammed.
Maintenance
1. Battery Replacement
When the keypad's backlight dims or the unit becomes unresponsive, it is likely time to replace the batteries. The keypad uses two AA Alkaline batteries. To replace them, open the battery compartment (usually located on the back or bottom of the unit), remove the old batteries, and insert new ones, ensuring correct polarity. Dispose of old batteries responsibly.
2. Cleaning
To clean the keypad, use a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the keypad's surface or electronic components. Ensure the keypad is dry before closing the cover.
