Right click key on logitech T-BC21 stuck

Over time the right click button has become hard to click. I assume it needs to be cleaned. I removed the screws on the back but it wouldn't pull apart. How can I get this appart to clean it?

SOURCE: logitech cordless keyboard erratic after cleaning keys

seems to be that you may have accidentally swept some dirt underneath the keys.
try pressing each key individually in word and narrow down the affected key or keys, then remove the affected keys (using a keyboard key removal tool, or very carefully by hand) and clean underneath the key with a small dry clean brush both under the key and the board section it lay in, then replace the key and type the key again, if that has no luck then try the process again.

hope this helps

Right mouse button closes window


1) Can you try the mouse in a different machine? Does it do the same thing?
2) Check your settings in 'SetPoint' software, or go to your Control Panel and check your mouse settings - you may have accidentally changed the settings for your mouse keys somehow.

3) Download the latest drivers for your mouse and re-install.

2002 honda civic key stuck in ignition, won't start, shift lever stuck


Your Civic has immobilizer, which means it will not allow duplicate keys. There are high chance that your old keys are worn out and this could be the reason. Any ways i would suggest you how to remove the keys but involves bit technical work . The LHS dash board part can be unscrewed and removed fully using the car manual, once removed the key holder joints to 4 brace compartment and there is a button beneath it, you need to press the small red button to release the key. This is not a standard method of removal, if your car has security alarm make sure you turn it off.. please remember - this suggestion should be followed only if this is your car. I;m not responsible for the solution being incorrectly followed without following manual.

Keyboard stuck


If you are addicted to your laptop, or are an overzealous typist, you may be dismayed when a key on your laptop becomes stuck. However, just because a key gets a little sticky, you don't have to run out to the computer repair shop. There are plenty of practical steps you can take to fix your stuck key right at home that don't require any fancy equipment, just regular household items.

1.Clean the area around the affected key. Use a damp cloth to clean the surface of the key (and surrounding keys) and then use a dry cotton swab to clean under the stuck key. Be careful not to pry the stuck key up with the cotton swab, as this could break the stuck key.

2.Press firmly on the stuck key. Sometimes after small dust or particulates are removed, the stuck key will pop back into place. However, if this is not the case, continue on with Step 3.

3.Pull out the fingernail cleaner extension of your fingernail clippers. This is the flat extension with a little hook on the end. Place the small hook under the left corner of the stuck key. A common reason that keys get stuck is that the collapsible spring becomes off-center. Gently push the key from side to side until it clicks into place. If this does not happen, you will need to disassemble the key completely.

4.Lift the top part of the key with the fingernail cleaner. You will see a collapsible plastic hinge (this is known as the Key Retainer) as well as a little rubber piece. Take both of these out. You will see a flat surface. Run the cotton swab across this surface to remove any dust.

5.Place the key components back in the keyboard. Place the rubber part on top of the metal circle you just cleaned with the cotton swab. Then place the key retainer (big side down) on top of it, and "click" it into place. It is very important to be careful with this step as these small parts break easily. Then place the stuck key on top of these parts and then give it a solid tap to click it into place. Your key should work now.

NEED TO PRESS REALLY HARD TO INCREASE VOLUME. EVERYTHING ELSE WORKS FINE


as time goes buy more of the keys will fail to work, pressing hard on the keys may do some damage to the circuit board inside. you need to remove the batteries any and small screws you can see then pry the two haves apart remove any screws that hold the circuit board to the top half and remove the circuit board to expose the bottom of the key pad you will see a black conductor painted on the bottom of each key button, use a Q-tip dipped in alcohol to clean the black conductor on all the keys then do the same thing to the contact points on the circuit board then rub a pencil eraser over the same contact points on the cicuit board and reclean with alcohol again.
This should fix the problem but it will happen again, and at some point even this won't fix the problem and logitech won't let you buy a new key pad, and that is the point I am at now and for that reason I won't buy another remote from them, I expect more than four years out of this product good luck.
