    I've tried 2 new batteries. It won't seem to learn the new code for some reason.

    We recently installed a new opener (same mfgr) and want to use the keypad. I have tried the "learn" button to no avail. Any suggestions would be appreciated.

    Craftsman multi-function keyless entry 139.53776 cannot reprogram with new opener Craftsman 139.53930DM



    Had to replace old Craftsman opener with a new one (2009) and thought that if replaced with new Craftsman, keyless entry unit code be reprogrammed to work with new opener. Instructions for the new opener describe the "Security+" opener as using a "rolling code transmitter". I'm assuming that the old keyless entry (1994) doesn't use a rolling code transmitter and therefore cannot be used?

THE FREQUENCY OF THE UNITS ARE PROBABLY NOT COMPATABLE THEY CHANGED ABOUT 2 YEARS AGO.

SORRY - I THINK YOU NEED A NEW KEYPAD TO GO WITH THE NEW OPENER.

How do i reprogram garage opener model 139.53776


To ensure that old codes do not work, first press and hold the SR code button (Learn) on the garage door opener's control panel. Hold the button until the LED goes out. The Learn button is a colored button that is usually on the back panel to the left of the force and up/down adjustment knobs. Sometimes the control panel is on the side of the unit.

Next get a helper to make the programming easier. One person will need to press and release the Learn button. Then within 30 seconds, the second person (or a fast moving individual) needs to type in a 4 digit code and press the enter key on the key pad. The LED near the learn button will flash when the code is received.

If you reset all of the codes, you'll need to repeat the fast press and release of the Learn button. Then press a control button on the remote for most of your other door opener remotes. (There may be a pair of remotes that came with the garage door opener that will never be forgotten.)

I hope this helps.

I've got water coming in through the bottom of my door at work. It's coming in a steady stream through a crack in the marble. Can someone please give me a pointer or two?


If you have water pipes/ heating pipes in the concrete floor then from the crack I would suggest that the floor movement has broken a pipe allowing the water to flow out the crack under the door. To test this turn the water off at the mains and if the water stops flowing after a short period of time then that will indicate the fault. Allow enough time for the water in the pipes up to taps to drain back out
