How to replace a key on Dell Latitude D620 Keyboard

When we use laptop we always meet the problem that some of the keys on your laptop keyboard is not working, but the others are good and there is no other problems with the keyboard, except some certain keys. Is it necessary to replace a new keyboard? NO, just some new keys is ok, or some keys from other broken laptop keyboards. It is much cheaper and very easy. Several days ago, one key of my Dell Latitude D620 Keyboard is not functional, then I found an old dell keyboard and took off the key, replace it to mine, then it works well now. And it costs nothing. The steps is as follows.
Step 1: Orient the hingeThe plastic hinge mechanism must be oriented as shown for it to fit onto the metal keyboard hooks without breaking. Notice the hole on the left side of the hinge is narrower than the hole on the right side. And then hook the right inner edge of the hinge over the metal hook on the base of the Dell Latitude D620 Keyboard.
Step 2: Secure the hinge into place“Stretch” the hinge over the right metal hook on the keyboard base. The hinge can actually slide apart slightly, which allows it to fit over both metal tabs on the keyboard base. Once it is sitting in place as shown, it will be easier to put the key on if you “compact” the hinge back together. That is, push the right-side underneath portion of the hinge towards the left. The hinge should now fit snugly in its place.
Step 3: Place the rubber spring pieceIf your keyboard is missing the rubber spring piece, place it in the center, with the large end down. It will be held in place by the surrounding hinge bracket in a moment.
Step 4: Insert the hinge mechanismInsert the bottom two white plastic tabs on the hinge mechanism into the plastic base piece, one side at a time. In the image below, the left side is being tucked into place first.
Step 5: Secure the hinge mechanismPush down and towards the top of the hinge to tuck the remaining top two white plastic tabs into place. A bit of even pressure should be enough to click the two tabs into place on the plastic base piece. The hinge assembly is complete and should now look like what is pictured. You can now check that the hinge works properly by pressing down on it. If it springs back easily, it is ready for the key to be attached. If it doesn’t feel right, you may need to remove the hinge one tab at a time and try repositioning the rubber spring piece.
Step 6: Press the key into placeAlign the key on top of its place on the Dell Latitude D620 Keyboard, and press down evenly. All four corners of the key should click into place.
However, please Note that the same laptop model can have several different types of hinge mechanisms under the key. Some colors in the pictures may differ for your model. That is fine, what matters most is the shape of the hinge piece.
