If you don't have the keycap remover tool you can try a butter knife or a flathead screwdriver. You can also try making a paperclip into an "U" shape and then bend the ends so that it can hook under the key. Once you have removed the cap from the key clean them off and wipe down the keyswitch.
You can also clean the key stems. These are the little towers that are affixed to the faceplate. Make use of a cotton swab, dipped in isopropyl ethanol to wipe off any debris that may be on the faceplate. Avoid getting any alcohol on the printed part of the key as it could cause damage to it.
Reattach the key after you have cleaned it. Start with the top left corner, and work your way down each row one key at a time. If you are using a new cap, align it with the switch on the key and press evenly on all sides.

2. Clean the key
It can be for many reasons that a key is sticky or mushy, but most commonly it's because the key isn't inserted properly in its base or key mechanism.

You can clean it by washing it in water or alcohol. If your keys are rusty and are dirty, you can clean them using salt and lemon. You can also soak them in a mixture of water and vinegar.
Before you start anything, make sure you close down your computer and disconnect it if you need to. It's important to keep yourself grounded as well since the last thing you would want to do is to damage electronic components by static electricity.
Start by wiping the whole key and its surroundings with a lint-free, dry cloth that you've wrung out well to prevent getting any moisture between the keys. Make sure you use a gentle cleaning solution since stronger cleaners can damage the plastic.
Then you can use the cotton swab that has been dampened with isopropyl alcohol (rubbing alcohol) to clean the edges of the key and its surrounding area. Be sure not to get any alcohol on the printed area because this could cause discoloration or even strip the lettering from your keys.
You can also purchase an electronics cleaning brush from an ordinary store to get rid of the stubborn dirt and dust. Finally, there are many products that you can buy in an emulsifying gel consistency which can be laid down over your keyboard, then peeled off to remove any loose debris from between your keys.
If you've tried all of the above options but your key is still mushy or sticky, it could be time to replace it. This can be a simple or complex process, depending on the type of keys. It may be necessary to disassemble the entire mechanism to remove the old key and replace it with a new one.
3. Reattach the keycap
We rarely think about our car keys - until they get broken or locked inside the car. This can be a major pain in the neck, but there are some things you can do to help fix the problem and save money.
The first step is to try using a can of compressed air to blow out any dust or debris that might be blocking the key switch. If this doesn't work, you can try prying the cap off of the key and clean it.
Make use of a plastic tool, like the credit card or Spudger. (You could also employ a knife if are in rush). Also, carry a small tool, such as a toothpick or tweezers for cleaning the tiny grooves on the keys.
After you've cleaned your key, you can reconnect the keycap and test it. If the key remains inactive, you may have to replace the key switch.
If your keyboard is too old or the key switch is damaged, then you'll need to buy an alternative. You can also solder it in place. This is a difficult fix, but it's often the only option if the key is no longer working.
Dust accumulation under the key is one of the most frequent causes for keys not to work. You can clean the area to remove any dirt and debris.
Another reason that causes a key to cease functioning is because the switch on the key has corroded. This can occur when water or a different liquid enters the key switch. It could cause corrosion, which will eventually eat away at the connectors and pins of the circuit board.
You can stop this from happening by cleaning the circuit board prior to replacing the key. This will help to make the switch more resistant to corrosion, and it will also make it easier to remove and solder in the new key switch.
If you're not comfortable fixing your laptop by yourself and you don't feel confident, take it to an electronics repair shop. They'll inform you if your key switch can be saved and be capable of replacing it if needed.
4. Test the key
It can be very frustrating and even dangerous when a key won't work to start your vehicle. If you require a new key fob, it can be costly. But, before you head out to the auto shop or an electronics store there are a few quick solutions you can test. The first thing you should do is try using an alternate key to ensure that your original one is not the problem. This will help identify the issue and save you money in the end.
If the key does not work after taking it apart, you'll find out what is wrong. The majority of keys are made up of three components: the key cap and the key carriage and the key pad. Each of these parts could cause different problems with the key. The cap of the key can be sagging or tilted. This can stop the key from snapping in place when you press the key. You can usually fix this by re-seating the key cap.
A damaged or dirty key pad or key carriage is a different possibility. These parts are extremely difficult to repair but can be cleaned with the use of a toothpick and tweezer. Be careful not to break any internal parts, though, as this can cause your key to stop working completely.
You can also try performing an experiment with a rollover test. This test examines whether or not a key can register multiple combinations of keys simultaneously. You can do this by pressing a number of keys simultaneously and then evaluating whether they all register correctly. If any of the keys fail to register, they might require cleaning or replaced.
Finally, you can try replacing the battery on your key fob. This is an easy and inexpensive method to test your key, and will aid in determining whether the issue is due to a dead battery or a malfunctioning ignition switch.
