If you can identify the model number, it may be possible to locate a manual from 1997 using the internet with http://www.google.com

According to one of the web sites above, "Stanley stopped making garage door openers and gate operators in 1997. Spare parts can be difficult to find however original and compatible remote controls are still widely available, most of the remote controls used by Stanley were manufactured by the Linear corporation.
Stanley made garage door openers for other companies and many parts are interchangeable some of the brands they manufactured for are Vemco, U-Install, Quiet Glide, Light Maker, Home Innovative, Whistler, Popular Mechanics, and Secure Code."

If the door is heaver than the original you may to adjust the opening force and the closing force. Check your instructions. The closest gdo I found was a chamberlain 8500. Go online to
Elite Series 8500 Garage Door Openers LiftMaster and see if this the same unit. The instructions can viewed . Good Luck

Are you referring to a black and decker garage door opener? And also are you referring to a keypad control on the outside?

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.

You're going to have to clear the memory on the openers. This is usually done by holding the learn button for about 15 seconds or until the led turns off. I'm not sure exactly what opener you have, so this may not be the case, if not, let me know exactly which opener you're programming your remote to.

Mine is doing the same thing. Did you get your problem resolved and if so what did you do? Thanks

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.

Here is some programming info for the Stanley.
