Be sure the remotes you have work with the operator you have. Check to be sure your batteries are good. Press and release (do not hold) the "Smart button). Press and hold the button on your remote about 2 seconds. If that does not work your remotes are bad or the reciever could be bad.

Our keyless entry pad flashes when we enter the code and press 0 to open the garage door. It used to work fine. Garage door does open with wall switch inside.

On this model of keypad, you should be pressing "Enter" to open the door. Find the "Learn" button on your opener (usually on the back, or under the rear or side light cover, a red square button), press it, then go to your keypad, enter your 4-digit code, and press enter. The opener lights should flash. If this doesn't work, there may be another issue, for which you will likely need to contact a repair service.

Door does not open or close when using the remote. It closes only when pressing the hard wired square white touch pad. Behind the opaque white touch pad, one can see a flashing/blinking green light.

Using a step stool, reach up and remove the covers (the white covers pop off). The instructions will be labeled on the back plate for setting your remote control's security code Make sure the remote has a battery installed and is compatible with your garage door opener. Or go to the LiftMaster web site and down load its operators manual.

How do you reset your code on the outside touch pad for garage door when you dont no the 4 digit code from previous owner

Get all the remotes together.
On the end of the GDO (where the wires are) is a "Smart" button.
Press and hold the smart button for 10 seconds (until the LED goes off). This will clear the memory.

Now press and release the smart button, take one of the remotes and press one of the buttons (usually the top, largest one). The light should flash on & off.
Perform this same procedure for all other remotes. Also do the same with the keyless entry. Always press the buttons slowly on the keyless entry. It is easy to mispress a button.

I have a craftsman garage opener and my lock won't work

The wireless keypad should work but the remotes should not. I suspect a bad wall control but there is a possibility of a bad logic board. If you have a neighbor with a 3 button wall control see if they will let you borrow it to eliminate that problem. Just make sure you note which wire goes where on the back of the control. They are color coded.
