Overhead Door opener LED flashes 13 times and keypad will not program or operate the door

Safety first: Use a stable ladder when accessing the keypad or opener. Do not lean on the door.

• 1. Replace keypad battery: Open the keypad cover and replace the battery with the correct type (often 9V or coin cell). Ensure contacts are clean and springs are not corroded.
• 2. Check keypad location: If mounted on metal or brick with metal mesh, radio range may be reduced. Try temporarily holding the keypad closer to the opener to test.
• 3. Reprogram keypad: Follow the Overhead Door programming steps: press LEARN/PROGRAM on the opener, then enter the PIN and press the appropriate key on the keypad. Watch for opener light flashes confirming success.
• 4. Verify compatibility: Confirm the keypad is designed for your opener's technology (e.g., CodeDodger 1 vs CodeDodger 2). Incompatible keypads will not program.
• 5. Test with a remote: If remotes work but keypad does not, the issue is likely with the keypad itself. Replace with a new Overhead Door-compatible keypad.
• 6. Check receiver if nothing wireless works: If remotes and keypad both fail and the LED flashes 13 times when attempting to program, the radio receiver on the logic board may be defective and require replacement.
