Thank you for taking the time to contact Sears.
It is difficult to say for sure whether this GDO will function with your existing keypad. However, if the existing keypad is Craftsman it should be compatible with this GDO.
If you can be able to provide any information about the existing keypad (ex. model number, brand etc) we can try to confirm. If the keypad is not compatible, you may want to purchase item# 18801 which is compatible with this GDO.
Have a great day!
