SOURCE: have chamberlain security plus 950cb lost instructions.
This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck

SOURCE: pad no longer works? on

Hello. When the pad no longer works, the problem is usually the battery. look carefully at the pad and you will see a screw holding down the battery compartment lid. Unscrew that screw, raise that lid, remove the battery, take it to radio shack and get a new one exactly like the old one. Joe

SOURCE: i have a stanley garage

The most important thing is to understand that the door spring can KILL YOU. If you are not absolutely certain that you know what you are doing, call a garage door guy. Many poeple get SERIOUSLY hurt.

So, you need two perfectly fitting rods to fit into the spring tightening end of the spring..
Release all spring tension. Release the opener.
Level the door with shims if necessary.
Install the first cable and turn the spring main rod to hold tension.
Put a vice grip on the main rod to keep it from unwinding any more
Release the 2nd cable spool and thread the other side cable. Turn the spool to have the same tension as the other cable.
Then wind the spring about 6 revolutions. (35 flats or tool insertions).

Verfiy the cable is still threaded correctly on both sides.

Correct spring tesnion is when the door will stay at 1/2 closed.
REconnect the opener and good to go.

Make sure the counter balance springs are ok. Most garage doors have 2 springs to provide counter balance for the door. Your garge door opener may have enough power to still operate even with one springs broken however with one springs broken would hit pretty hard. It the springs look ok I would release the door from the opener (while in the down position) using the little rope that hangs down and operate the door by hand to ensure it goes up and down smoothly. Most problems are due to friction caused by bad rollers or failed springs. If this is not the issue let me know.
Hope this helps

Try searching around here to find similar or hopefully exact opener. Stanley no longer is in the garage door business, and the company that bought them out went bankrupt.
Good Luck

How to reset garage door opener pad without old acess number

A Stanley garage door keypad is wall-mounted, battery-operated device that allows you to open your home's garage door electronically without having to manually lift the door or use a pull chain. The keypad uses a four-digit access code that you program after the keypad is initially installed. You can change the code, disable the keypad manually by entering a invalid code and reset the keypad if the device is not working properly. After you reset your Stanley garage door keypad, the device is ready to accept a new access code.

Stanley has been out of the garage door opener business for over 15 years. I reccommend replacing these openers when they start acting up because it is so difficult to get any parts. There is a reason that they went out of business.
