Craftsman remote LED lights when pressed, but the opener does not move or click; no error flashes on opener.

Safety first: Stand within sight of the door while programming remotes to avoid unexpected movement.

• Replace battery: Open the remote and install a fresh coin-cell or AAA battery as specified. Ensure correct polarity.
• Verify compatibility: Check that the remote model matches the Craftsman opener's frequency and security type (e.g., Security+ 315 MHz, Security+ 2.0).
• Reprogram remote: Press and release the opener's LEARN button. Within 30 seconds, press the remote button you want to use. The opener light should blink to confirm.
• Test range: Try operating the door from various distances. If it only works very close, interference or a weak battery may be present.
• Replace remote: If programming fails repeatedly, the remote transmitter may be defective and should be replaced with a Craftsman-compatible unit.
