A flashing keypad may also signal that the battery is running low. Most Craftsman keypads use a 9-volt battery, which should be replaced annually or whenever the keypad starts flashing unexpectedly.

3. Signal Interference

Signal interference from nearby electronic devices, such as Wi-Fi routers or baby monitors, can prevent the keypad from communicating effectively with the garage door opener.

4. Keypad Malfunction

Internal wiring issues or worn-out components can cause the keypad to malfunction, resulting in flashing lights.

5. Incorrect Code Entry

If you enter the wrong code multiple times, the keypad might flash to indicate an error.

6. Outdated Firmware or Compatibility Issues

Older Craftsman models may not work well with newer keypads due to compatibility issues, leading to flashing.
