Keypad will not operate the door, but remotes and wall button work normally.

Safety first: Ensure the door area is clear while testing keypad operation.

• Replace batteries: Fit new batteries in the keypad, observing polarity.
• Re‑program keypad: Follow the Cardale instructions to put the opener into learn mode and then enter the keypad PIN to pair it.
• Check mounting location: Avoid mounting the keypad on metal surfaces that can block the signal.
• Inspect for water damage: If the keypad is cracked or has signs of moisture inside, replace it with a Cardale wireless keypad of the correct type.
