As long as the remotes you have are set up for your door, you can use as many as you can buy.

HBW077 Craftsman: door travels downward only 10"

Sounds like you have a bad RPM sensor board. This is a small printed circuit board just in front of the motor. It's job is to reverse the door when it hits an obstacle but will act as you describe when they go bad. The part number is 41C4398A and is available at Sears or any good door service company.

Check to see if the wall control has 3 buttons. If it does one of them is the lock button and you need to press and hold this for 3 seconds. The lock button has an icon of a padlock. If you do not have a 3 button wall control programming the remotes should cure it.

Keyless remote will not learn new 4 digit code

Press and immediately release the smart/learn button and walk over to the keypad and key in your 4 digit code and press enter. If this doesn't do the job your keypad is probably bad.

Need device to operate more remote controls

The memory is limited and I think it is about 5 remotes including the keypad but there are older openers that are backwards compatible and will work with remotes with 9 position dipswitches. One model I am familiar with is the Liftmaster AD 800. You will have to call around to companies that handle Chamberlain and Liftmaster to see if they still have one. They will work with unlimited remotes as long as the switches are set exactly alike.

Liftmaster wireless keypad closes but won't open the door

If you are sure the battery is good you have a bad keypad. The signal strength is so weak it will not penetrate the door.

Garage door opener.Working off and on. Green light blinking

Check the alignment of the safety light beams near the floor on each side of the door. They are not properly aimed and the safety reverse feature will not allow the door to close properly.
