Check the door springs. Could be one is broken. Also remove the motor unit cover and check the drive gear. This is common when that gear starts to fail.

My 05 passat will not open some doors sometimes, will open all other times and also will lock all doors except driver door sometimes but other times will lock them all please help? was wondering if it was...

It isn't a key problem, but it's most likely to be a door actuator (motor) issue, if indeed it is an issue.
Many cars these days are fitted with a two stage lock program. This means that the first time the key activates the 'open' command then only the driver's door opens. You have to press the key fob twice to have all the doors open. This is a security feature to prevent potential criminals from breaking in other doors and snatching valuables when you activate the locks. So now the driver has control over one door or all doors, depending on their requirement. On these types of modern systems there is often a method of setting the program to open one then all with the single key press, or all doors at the same time with one key press.
Anyway, just try one press and see if it opens the driver door only and then try two presses to see if it opens the other doors. If it works this way, then it is supposed to work this way.

Both of my garage open by themselves toghether for no apparent reason? One door is a month old and the other is a little over a year old. I redid the codes on both, but that did not help. Both openers are...

Both being plugged into the same circuit should not be a factor. I would call the manufacturer of the newest unit and report the problem. They may know of the problem.

My opener opens both garage door I only want it to open one

You will need to erase both openers out and recode.

Press the learn button on the motor head until the led light goes out on it. Wait for 2 minutes. ----- Press and release the learn button and then press the button on the remote 3 times and try. Genie openers sometimes take multiple times doing this to code in for some reason. For multiple remotes repeat from -----. For the other opener do the same thing but with a different button on the remote, unless you have a 1 button remote then use different remotes for the 2 doors. Thanks BB

I have 2 liftmaster door openers and 1 387lm Wireless keypad.can I program it to open either door?

To program that thing you need to locate the smart/learn button on the back of the opener near where all those white wires go. Press and immediately release this and then walk over and key in any 4 digit code you like and then press 0. The zero acts as the enter button on other keypads.

Genie Compact 3-Button Remote control will only open 1 door/not 2

On some of the remotes you will find a toggle switch to change frequencies, this might help. Note all new openers are operating on a different frequency than slightly older ones due to military interference. Even though both might be intellicode they might not work together on the same remote. Sometimes some openers are harder to program than others. So lets try to program the harder one. You need to find and press the learn button on the motor head. Then press the button on the remote once. The led light by the learn button should not flash. If so try it over. The light should either stay lit or go out after the first press. If it does press it again and then a third time. If it ever flashes during the program process try again. The third or fourth time the motor should operate. If not you either have a bad remote or more than likely a bed logic board. Thanks BB

Bosch SHY66C05: interlock broken, dishwasher rinse-aid leaks, and soap does not open (sometimes)

door lock is in the wrong position. open door and use 2 small screwdrivers to lever lock to correct position. bend the hook on the cabinet slightly downwards if it is a metal hook
rinse aid and detergent dispensors are 1 item. could well be faulty but can also be module. check you are getting volts to the solenoid at appropiate part of the cycle
