Blackwidow V4 X - a few keys are delayed and unresponsive

Hello, i have same problem with my K, looking for RMA

Same issue.  Started with the D key, so I learned how to solder switches, opened the keyboard, replaced the switch with another that I never hit, and it worked for a bit.

Then a week later, the A key was acting up.  Did the same thing.  Now today, the Y key is having the same issues.

Getting tired of it.  Keyboard is less than 3 months old.  There is no firmware update option on Razer’s support site for this specific keyboard.  No options in Synapse to try to fix this. 

Same here, I opened a support ticket, and waiting for their response.

Did anyone find a fix?

I think it is a firmware issue, I exchanged the keyboard for a different brand

I am also having the same problem and I only got it 2-months ago, working fine back then

Yea I have been looking for solutions for this for a while. I have been a Razer customer for half a decade. My keyboard, mouse, mouse pad,  headset, and any peripheral I’ve owned in the last 5 years have all be razer. I used to like them a lot, but both of the last two product I’ve purchased from them have been absolutely awful and defective after less than 3 month of gaming  2 days a week. Support is unhelpful as I bought them from target and no longer have the receipt. Where was the QC testing? Was there any at all? 

I’m am considering reporting Razer to both the FTC and BBB. It is clear after spending time going through these forums that this is not just an issue I’m having, and Razer employees have not commented anywhere or offered any kind of solution. In fact I feel as though they are burying their head in the sand. These keyboards should have been recalled. What I’m left with instead is a $150 Paperweight. At this point, with this many defective keyboards, its quite literally just a scam. 

I have the problem on the L , sometimes works , sometimes have to press more than once .

It just sux a 150€ keyboard have this problems , i mean….this problems should be found on 10€ ones , not  premium quality ones , this is very sad .

I bought barracuda X , deathadder v3  mouse ,  goliath mousepad  and this keyboard all at once , so i spent ALOT of money on it , the minimum i expect is they last some YEARS , not weeks...

My Blackwidow v4 is less than 3 months old (purchased early May) and first the d key was not responding more and more frequently. No time yet to troubleshoot, tried removing the key and a couple around it, cleaning it out. Seemed to help, but not for long. Then the f key started having the problem. Disappointed to find this is a known problem, but I had a suspicion I might, being that my keyboard is less than 3 months old. I had to switch to my old Durgod because I use it for work, and this week has been so busy, i didn’t have time for this recurring issue. Going to contact Support tomorrow and see what they have to say about it.

I’ ve returned to this post after I posted an hour ago and my post was removed or not saved. Strange. Same as you guys had my Widow V4 X for 3+ months and the ‘e’ key just sometimes works and sometimes it doesn’t and I firmly press it down.   

I don’t eat food near my keyboard, I haven’t dropped it or smashed my fist on it or spilled any liquids on it and it’s clean. So I don’t know why my ‘e’ key sometimes works and sometimes doesn’t.  I am willing to try anythin

g.

I’m not sure how this has happened but doing testing on this the ‘e’ key is certainly intermittently unresponsive. I’ve tried a firmware update, I’ve tried uninstalling Synapse and tried it on a different PC and the same result. 

Looking at my Amazon purchase of this, I bought it back in March 2024 so I’ve had the keyboard for 4+ months not 3 but still it’s very disappointing.

A good test for unresponsive keys problems which are intermittent is to type a sentence many times with the letter of the key. Also not sure about the support for this as online for this keyboard it states that you can change the polling rate on the keyboard by going to Synapse->Keyboard->Customize->Polling and there is no such option in synapse to do this. Very poor. Even typing this message the ‘e’ key has failed me several times.

Ok I am back to report on that ‘fix’ that I provided the YouTube link to and it’s early days still BUT IT WORKED ! the ‘e’ key on my Black Widow X V4 is now working again and before it was intermittently unresponsive so back then before the fix 1 out or 3 or 1 out of 4 ‘e’ key presses would not register.

So to reiterate, , I unplugged the keyboard, I got one of those tiny  plastic spray bottles that (say) you could spray perfume or aftershave out of, filled it with isopropyl alcohol, took the key cover off, sprayed the GREEN micros witch, pressed it up and down and ‘gently flicked it’ like the guy did in that ‘How to properly clean your microswitch keys and maybe fix them’ Youtube video, they I used a cotton swab to sweep along the edge of the wet microswitch, then sprayed some more isopropyl alcohol and gently waggled the microswitch, I left it to dry for 12 hours or so then came back plugged in and  it just worked !! the ‘e’ key just works as normal 100% even if you press it gently. 

The test was for me typing in a sentence into Notepad really quickly which had ‘many’  letter ‘e’ s in the sentence; typing in that long sentence repeatedly and all the letter e’s in the words came out fine! with no missing letters.
