I have a strange Problem with my second hand A1243 (With Swiss Layout) Keyboard.

If I use left Shift + E it doesn't do anything, but if I use right Shift + E it works.

Everything else works so far.

Has anybody any idea what that could cause?

Thanks in advance.

Can anyone help?

I have an Apple Wired USB Keyboard since 2013 and yesterday some keys stopped to work.

I didnt pay much attention, thought it was a momentary USB glitch, replugged it, and it seemed to help.

But today the trouble returned.

Keys "8", "I", "K", and "," are not working. As you can notice, they're all in a straight line. So it feels like some contact line is dead/malfunctioning.

No, I didnt spill any liquid. Its perfectly dry.

Googled it. Many users report the same problem here and there, but not the real remedy.

Apple's answers are as useless as they should be, deemed to housewives, a la "Check if your house has electricity". :)

If you can give a tech-savvy advice, please do.

PS: If you're going to say "Go buy a new one" - thank you in advance. :)

56

-/

ty

=[

gh

bn

For example, when I press '5', it produces '56', and the same when I press '6'. It too produces '56'. Same for the whole list above.

Note too the apparent pattern down the keyboard with the '56', 'ty', 'gh', and 'bn' combos.

I've checked battery level. It's nearly full charge. I've tried using while plugged in and charging. I've tried gently lifting affected keys and blowing out any possible dust, particles, etc. None of this has helped.

After comparing it with the same model of others, I suspect that the copper wire of the copper cable may be oxidized. I want to fix it by replacing the wire.

So, what should I pay attention to when replacing the wire? Also, how can I search for relevant repair methods on iFixit?

我的2016年以前的软塑胶材质苹果妙控键盘（型号A1829），几年前还能正常使用，现在无法连接设备。对比同款键盘后，推测可能是铜排线（铜导线）氧化导致的问题。想通过更换导线来修复它，请问更换导线时需要注意哪些事项？另外，想在iFixit上搜索该型号键盘的相关维修方法，应该如何搜索?

I’ve already tried the following:

• Resetting the keyboard
• Removing (“forgetting”) the device from Bluetooth settings on all other devices
• Ensuring the keyboard is fully charged

*

Despite these steps, the keyboard still won’t connect wirelessly. Has anyone experienced this before or have suggestions on what else I could try?

So, I bought this A1314 keyboard off of the flea market. And I'm not sure whether this issue I'm having is hardware or software.

The problem is that the keyboard turns on, enters pairing mode, but I can't type anything on it. And, as far as I understood, you need to type the PIN code for BT pairing from the actual keyboard itself, which I can't since none of the keys work.

I tried the Caps Lock key and it doesn't light up. So...pretty sure it's a general issue. The question is: is this hardware or software? I couldn't find this issue online, so I decided to open a new topic for it, in case other people have the same issue.

Also, is there a way to reset it...? Under BT settings on my Mac, it still shows up with the previous owner's name on it. I tried long pressing the Power button, but....no success. It turns on, LED light starts blinking twice, which I'm guessing means it's in pairing, but...when trying to connect it to my Mac, it shows the PIN I should input, but looks like nothing happens when typing and pressing the Enter key.

The keys don't seem to be sticky or anything, so I don't think there has been water (or at least anything sugary) spelled on it. But yeah, right now, I can't type anything on it.

Any idea?

Update: this seems to be hardware after all.

Problem:

Big Sur UI highlights each keystroke so if one of the keys required for pairing don't work, you can easily see it. Too bad this hasn't been kept on newer versions of MacOS.

If I apply very little force, it sometimes does not work, maybe two out of ten strokes. If I apply excessive force, it works every time.

What is the recommended way to troubleshoot this type of issue? I removed the keycap, but didn't see anything obvious, such as signs of spilled liquid or excessive grime.
