Check you lock or vacation switch

When you garage door won’t work from the remote controls but works properly from the wall console inside the garage you need to check the lock or vacation switch.

The lock switch is used to disable the remote controls. On Chamberlain garage door openers – includes Liftmaster and Sears systems the lock switch is indicated by a padlock. If the system is locked then the green indicator on the console will be flashing or the words “Lock Mode” will appear on the LCD display for Elite and Estate series openers. To unlock simply press and hold the LOCK button for 3 seconds and let go. The indicator should be on steady / Lock Mode text will disappear. Try your remotes as the should work now. The procedure is similar for Genie / Overhead systems but the indicator will go off when locked (instead of flashing).

On most systems the lock switch does NOT disable an outside keyless entry. You may want to test this on your system. When going out of town for an extended period you may want to unplug the garage door opener for added protection. It should be noted that on systems like the Liftmaster 3850 which have a battery backup that unplugging the system is not recommended since the battery would still allow approximately 30 cycles of the garage door.

Instructions for many garage door openers are on our website at http://www.gdcorp.com/instruct.htm and search for your model opener.

If you cannot resolve the problem yourself and are located in our service area we can schedule a service call.

      If you have what we term a vault garage (ie no side door) then you should have a vault release (aka outside disconnect) which is a lock and cable installed in the top section of the garage door. When you insert the key into this device and turn the cylinder will come out with a cable attached and allow you to pull the manual release just as if you were inside the garage. You can then lift the door manually. If you do not have the vault release then you may want to check for a window to gain access.

      We have drilled the hole for the vault release and used a hanger to “fish” for the release string with fairly high success. Then you install a vault release to protect yourself in the future.

      If you have a keyless entry (numeric keypad) the lock switch does not disable the keyless entry on most Chamberlain made openers which includes Chamberlain, Sears, and Lift-Master.

      Good luck
