Ken, you may have to reprogram transmitter after battery change, check your manual, if you do not have manual, Google search your make and model# manual.

Is it the vehicle battery or your remote battery? If it is the remote battery change it. Many vehicles have a manual lock as well so you can open the door with a key. If it is the vehicle battery you will need to get a door open so you can get in, pop the hood and get access to check/fix the vehicle battery. I hope this helps.

Yes you change the batteries in a garage door opener remote. You can find on at your local pharmacy. If you have to push the button several times and the batteries don't help you may need to replace the remote.

I assume you mean that the entry keypad works when the door is open but not when the door is closed. This usually indicates that the signal strength on the entry pad is low. Try changing the battery.

Insert a small Philips screwdriver in the opening on the bottom of the battery compartment cover. Pull the cover slightly outwards then pull the cover down. The battery in the compartment is a 9V battery. Then replace the cover by inserting the lip in the top of the battery compartment and then snap it into place.

If you change the battery quickly, you shouldn't need to reprogram the opener. If a new battery doesn't solve the problem, check what may be causing signal interference when the door is down. (Consider moving the keypad to a spot closer to the door opening. I know that we have the keypads placed on the side of the door jamb on our garage doors. When the small handheld remote units start to loose their batteries, bringing the remotes to that area that often works.)

I hope this helps.

If you changed the battery in the keypad and it drains the new battery then it is bad.

Do you mean the numeric keypad is no longer controlling the garage door? If so, have you changed the battery for the keypad? Frequently, if the battery is low, the keypad will stop working when the door is closed but works to close an open door. On most Chamberlain garage door openers, this is a 9V battery. You may need a small Philips screw driver to open the battery compartment at the bottom of the keypad.

After changing the battery, try the learn code procedure again. I've found it easiest to have two people involved when programming the keypad to the garage door opener. One handles the Learn button and the other types in the desired code.

I hope this helps.

WHEN YOU CHANGE THE BATTERY NO NEED TO REPROGRAM THE REMOTE.
THE FLASHING LIGHT TELLS YOU IT IS SENDING A SIGNAL THAT IS BEING RECIEVED IT IS JUST NOT THE CORRECT CODE TO OPEN THE DOOR.
REPROGRAMING THE REMOTE SHOULD SOLVE THE PROBLEM

HOPE THIS HELPS

Reset the Liftmaster unit. There should be a red reset button on the unit in the garage. If this does not work, reset the breaker. Good Luck!

WHEN YOU CHANGE THE BATTERY YOU NEED TO REPROGRAM THE UNIT.

IF THAT DOESN'T WORK YOU PROBABLY HAVE A BAD KEYPAD.

HOPE THIS HELPS

Reprogram the remote. Press the learn button on the back of the opener and then press the remote button until the light on the opener blinks once.
