I had a similar problem with my Delta; the MT socket may have dirt in it that prevents a tight fit, or there is a slight machining error. My solution was to clean the joints, and place a drop of Krazzy Glue on the taper, and ram it home - has stayed put for the last 20 years!

Re: garage door opener . i recently replaced the battery in my craftsman wireless keypad now the code doesnt work and i cant get the door open to press the reset button. how do i fix


Changing the battery wouldn't have caused the keypad to quit. You must have had a problem before the battery change. If you have a vault door. That is one with no other way to enter you will have to call a door technician. They can drill a hole in the door, use a special tool to pull the release and then install a keyed release in the hole they drilled.

We have a LiftMaster 973LM model - the remote only opens the door, but when it starts to close, it only goes down a tiny bit, then goes back up. The "Inside" remote however, you now have to press...


Check the sensors in the doorway. They must be pointed at one another and the small light on each one must be lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have bad sensors.

It appears that the straight door arm extension is about 1ft short. I have a high garage celing and the garage door tracks are high also. Do they make an extension to the extension?


I had the exact same problem. I didn't know if you could get an extension or not and couldn't find anyone who could help, so I bought a 3' section of predrilled 1 1/2" by 1/8" iron. I cut them into 4, 8 inch sections and made my own extension so that the two (I put three) hex bolts would keep the arm straight. It worked like a charm and all the safety features are now functioning.

Your door sensors need to be pointed at one another to work properly. The small light on each one must be on and not flickering. Tweak them a bit.

What kind of a tool do I need to open the keypad so I can replace the battery? The keypad is for a 1/2 HP LiftMaster garage door opener. Most of the ones I have seen use a philips head screw driver, but...


I have never seen a keypad that didn't take a phillips screwdriver. I would be tempted to drill out whatever is there and find a screw to fit after changing the battery.

Reset Craftsman keyless entry pad.


What you are asking for is not possible. You need to call a garage door repair technician. They will drill a hole through the door and using a special tool can pull the rope to release the door.

Remote control to garage door only works when iam one inch from u


I had a simaler problem, after installing a shelf to get rid of clutter and organize tools. I had traced it down to a Rigid cordless drill charger. The garage door opener signal was interfered with only when the battery pack was on the charger,my other drill charger have no affect on the garage door remote performance but when I charge that battery pack the range is cut down by 75 to 100 feet, it is amatter of finding out what is interfering with your signal. Same principal as using a jammer to disrupt police radar. I hope this helps
