There are some reasons why it is not working
1- If '2' as well as '@' does not work, the key is sticky or broken. press the '@' key then press any other similar key, for example '#' and see if you notice any physical difference. If you do, take the key off carefully by getting a blunt object such as a butter knife and carefully pry it off and check to see if it looks to be in working order. If you can't tell pry open a similar key, for example '#' and look to see any physical difference with the keys. To put the keys back, simply place the keys back where they belong and apply force until you hear a clicking noise.
2- The keyboard may be faulty and not recongnise '@' when you press it. first unplug your keyboard, plug it back in and try again to see if it works. If no change replace keyboard

Hope This helps

My 96 Ford Taurus anti-theft light flashes in the morning. Car will crank over revs will go up then car will stop. After a hour or two it starts then goes very good all day until I go to start it the next...


Your key is failing, hence the flashing THEFT lamp.

If you have a backup key at home, try that one. If it works, and you can get a moment where your 1st key is in the mood to work, you can buy a new key from a locksmith and add it yourself, then throw away the bad key.
There are several variations of THEFT system, and the procedures are similar. Oldest and easiest requires 1 working key in hand to set the car up and allow you to add a new key. The next version requires 2 working keys, but the procedure is the same.
Insert 1 key, or one of of your 2 working keys, turn to run, then remove. within 5 seconds, insert the other key, turn to run, then remove, NOW insert the NEW key, turn to run and watch the THEFT lamp. After 3-5 seconds the lamp should turn OFF. If it does, the new key is accepted and programmed. Throw away the bad key as it will simply become a problem and you cant trust it and the thought someday it might work will simply strand you one day.
If you DONT have a working spare, go buy 2 keys anyway matched to your broken key. You will need 2. If your car is the earliest version (available in 96) you MAY be able to add new keys with 1 working key and your current key works sometimes you say.
Do the above with your 1 old key or with 2 if you have a spare, try the 2 new keys one at a time and see if the theft lamp will turn off. If that fails, you wont lose anything, the new keys are still good, but must be programmed with a scantool. Any good repair shop that can handle programming for FORD will be able to do it. The tools that can do it are fairly common nowadays.

(B) though not solve and keypad direct on pcb first you try to good clean full pcb with cleaner.
© though not solve now you try to format/flash your phone because some time key problem come from software problem.
(D) though still not solve now you check must be CPU. 95% china phone keypad directly going in cpu. and other 5% first going to resistor or capacitor near the cpu or keypad than going to cpu. so now first check them than you can try to re-hot, re-soldering or changing cpu.
(E) though its flex or socket system, first check GND connection continuslay pcb to key panel. next check full flex or socket all line going continuously pcb to key panel or not. also sometimes flex or socket shorted with other line or gnd so check also them.

My Samsung laptop's (np-r430-jb01ae) function keys are not working. how could i solve it?


Step 1:
Function keys are special keys used for assigning program shortcuts and specialty tasks to the keyboard. They are located at the top of most keyboards and labeled "F1" through "F12." Some keyboards may only feature 10 function keys, while others may have as many as 18. These keys often go unutilized by the average computer user, but they may have very important tasks for some users, which can lead to problems when the keys do not respond. Fixing nonresponsive or malfunctioning function keys is quite simple, and should only take a few minutes.

Connect your keyboard to your computer, and power it up. Open a program that uses the function keys such as Microsoft Word or Microsoft Excel. Check your keyboard for an "F-Lock" or "Function Lock" key. This key is used to toggle function-key support; when it is toggled on, the function keys will not work. Press the "F-Lock" key and then try using a function key in the selected program. "F1" is a good key to test, because it is set to open a "Help" document in all Microsoft software. If the key does not work, press the "F-Lock" key a second time, and test the keys again. If the keys still do not work and you are running the Windows 7 operating system, you may need to install a "hotfix" from Microsoft to fix the key functionality. Navigate to the link entitled "Microsoft Support: Some Function Keys do not Work Correctly." (See Below.) Some function keys or keyboard shortcuts do not work correctly on a computer that is running Windows 7 http://support.microsoft.com/kb/975741 Resolve unexpected Function (F1 - F12) or other special key behavior on a Microsoft keyboard http://support.microsoft.com/kb/894513 Click on "View and request hotfix downloads" located beneath the title of the article to access the Microsoft Hotfix database. Agree to the terms and conditions, then download the hotfix. When the download is finished, run the downloaded file and follow the on-screen instructions. You may need to restart your computer after the installation is complete. Your function keys should now work properly.

Shift key not working


You have 2 Shift keys on the keyboard. If the other shift key is working then the shift key that is not working is defective. You should consider replacing the keyboard on your laptop. There is no setting on Windows that can disable the shift key.

**Note : If both Shift keys are not working, Try to check if sticky keys feature on windows is on. Sticky keys should be disabled. To disable sticky keys, Click on start and Go into control panel > Accessibility Options, and under keyboard there is sticky keys. Remove the tick and click apply and OK.

**If "Use Sticky Keys" is unchecked, that means sticky keys is disabled.

I HAVE A NEW ACER 5517 AND CAN'T GET THE @ KEY TO WORK???


First, does the #2 key work? I assume thats the same key as your at button.
If it does, if you hold the shift key and press 3, do you get the pound sign?

if the 2 key does not work, then the problem is with your #2 button. if the # key does not work, then the problem is with your shift key.

Try the right shift key, blow air into those keys, if it still does not work, you will need to replace the keyboard.

it will be covered under warranty.

Keys don't work in random pattern formation


The keys are scanned in a matrix. It sounds like two of the matrix lines are broken. They may be broken on the board which the keys contact. These are often conductive rubber "pills" pressed onto finger like patterns of circuit traces. The traces have a black coating in the contact area. If the keys have been "mashed", sometimes the board is cracked. IF the crack goes through one of these contact areas, that is fatal. That board needs to be replaced.
A loose cable where two wires of the matrix aren't contacting would do it as well.
