IMac Aluminum Keyboard not all keys working

I have an iMac with the aluminum wired keyboard. Suddenly, some of the keys have stopped working, including "l", "u", and "?". Since these are frequently used letters in the English language (among others), is there a way to fix this without buying a new keyboard. Many thanks for your help

    My problem is with capital A. I'm unable to use the shift-a combination to make the upper case version. I have to use the CAPS lock key until I reboot. It comes back after a reboot.

    I've got a similar problem today. u-i-o-p, j-k-l, m weren't working. The problem was a mouse key.

    system preferences< accessibilityI realize that some of the keys were doing the mouse job. So then uncheck and everything should come back just fine!

Remove macair keyboard?

since it is a unibody design (the whole computer's made of one piece of aluminum to please god knows who) you can't remove the keyboard in one piece. Rather, you must take out each key individually. This is done by putting a small flat object (butter knife, screwdriver, tooth of a PC fanboy) into the crevice between the aluminum and the key, and prying upwards very carefully (READ: very very carefully). if you were hoping to replace the keys with a new set, you then need to pry the small plastic ring under each key off the removed key, and attach that to the new key, and then gently (READ: very very gently) push that back into the open keyhole. since you did not explain why you want to remove the keyboard that's all i can say, but if you need any other help i'd be glad to.

IMac Aluminum Keyboard not all keys working

Hi Bilbo,

Do you know if the keyboard has come into contact with any liquid? That can cause shorts in some of the connectors. Regardless of reason for failure, these keyboards, when they start failing, do not have repair options. Purchasing a new or used one will be the only option.

Keep in mind that these wired keyboards are also no longer made by Apple, but you can find them online at various sites. You can also use different Apple-friendly brands like Logitech if you'd prefer to stay with a wired keyboard.

Operating System doesn't deal anything on your problem. The problem depends on the brand of you computers or the type of keyboard you are using.

The GCS632U is designed to work with standard USB keyboard and mouse only. And wireless and gaming keyboards and mice are not guaranteed to work correctly with this KVM switch. If any one of you is using the new Mac Aluminum keyboard, this keyboard will not work with the older version of the GCS632U. But IOGEAR releases a new batch of GCS632U that would work with the Apple Aluminum keyboard.

If you have an Apple Aluminum keyboard that does not work with the GCS632U, you may contact the IOGEAR Tech support and they will process a Return Merchandize Authorization (RMA) if your device is still under the warranty period.

To resolve your keyboard issue, try to power cycle the KVM switch by disconnecting it from the computers, disconnect also the keyboard and mouse from the KVM switch. Leave it disconnected for two minutes. After two minutes, reconnect everything and reboot the computers.
