Trying to replace Space barafter cleaning.

Will the long edge snap into the clips on the base, or the space bar? Place that first. Then aligning the two ends and the post and push down.

A key falling off of a keyboard might be an annoyance, but it is not a reason to buy a new keyboard. Regardless of which key falls off, it can be replaced fairly easily. Although the method of replacing typical letter keys is a little different than replacing the space bar, replacing either of these types of keys can be done in a few minutes.

Carefully pry the key from the keyboard next to the key that has fallen off. This key can easily be pried by sliding a flat-head screwdriver underneath it and popping the key out. Be careful to make sure the key retainer underneath the key stays in place, especially if the key retainer has also fallen off the key you are attempting to fix. Look closely at the key retainer underneath the key that was just removed. Notice there is a notch in each corner of the key designed to hold the key in place. Place the key retainer back into place if it has fallen off the key you are trying to fix. Make sure it is positioned exactly as the key retainer next to it is. Put the key on top of the key retainer. Use your index finger to firmly push straight down on the key to lock the key back into place. Do the same to the key that was taken off to view the other key retainer. b> Replacing the Space Bar b> Turn the space bar upside down and use a flat-head screwdriver to separate the retainer from the back of the space bar key. Place the retainer into its place on the keyboard. The retainer will hook into small hooks on the left and right sides. The small metal bar from the retainer should line the bottom of the area where the space bar will be placed. Put the space bar back into the place where it belongs. Spread the ring finger, middle finger and index finger across the space bar, and push firmly until the key snaps into place. Put the space bar key back in place and gently press on it with fingers until it snaps back in place.

Hi

As you said that the Right and left buttons are not working as well as the space bar, then it could be the issues with some dust particle inside the keyboard.
Try to clean it. Try to use it hope it will work , but in case it don't work then you need to replace the Keyboard.

In case if you have any more trouble do contact back in Fixya.
Thank you

Have you gone into the device manager and trying to update the driver? If that's not it, try uninstalling it and shut down and restart the computer? It will reload your driver for you. That's all that I can think of.

Some dust or liquid must have entered or dropped on the keyboard. If it is just dust try using a compressed-air spray canister to blow in the space around the key.

If that does not work you can use a thin knife or flat screwdriver to pry the keys off. Do that with the 3 key first as the space bar is more difficult to put back in - there are a couple of springs that have to be fitted just right. Clean away any dirt and push the key in place.

If it is a liquid then you must open the entire keyboard panel and clean it from the inside. If you have the confidence and skill to do that you can try searching samsung support about how to do that. It is not that difficult if you follow the instructions carefully, but if you yank the flat cable connector off it may be difficult for you to snap it back in.Otherwise ask for professional repair.

There is a rubber part that is designed to spring up when you release the space bar - this is the contacts that is the electrical push button. At each end the metal bar is hooked to the plastic (the long space bar key). There may be a couple springs found as well - they should seat on the base. Connect all pieces and place the space bar key over the area where it aligns to the keyboard and snap it place with a slight force.

On dell's website there is a step by step instructions on how to attach it back on. I had to do the same thing on mine machine. Just go to dell's site and on the search bar on how to attach the keyboard.

you can replace from any keyboard that is no more working. just remove the metal bar and replace it with yours. Except you want to buy another keyboard.

You can also try fixing it later, you might get a solution on your own, maybe you are exhausted or worn out. Just relax your brain and by the time you go back to it, You might just get it right this time around.

Wish you the best of luck.

Get a Electrical/Electronic solvent spray from RS, give it a good spray (with Power Off!) and operate it lots of times. The spray will evaporate naturally and may remove the gunk! Ian.

The space bar key is connected tothe keyboard a little bit differently then any other key.

There is a metal retainer connectedto the space bar key (on some keyboard models). Separate the retainer from thespace bar key with a flathead screwdriver.

Install the retainer back inplace as it shown on the picture. You have to engage the retainer with thesmall hooks on the keyboard.

Put the space bar key back inplace and gently press on it with fingers until it snaps back in place.

That’s it. The space bar key isinstalled back in place and should work as before. If you still cannot fix yourkeyboard, then you’ll have to find a new oneand replace it.
Pleas rate my solution on fixya if you are done.
