Deathstalker v2 tkl bluetooth issue

I have the same problem. The bluetooth has gone crazy. Only the slow blinking appears, and when it syncs with a device, the blinking doesn't stop, and it only works momentarily. After a while, or changing modes or devices, it stops pairing.
It happened to me in firmware version 1.6, and upgrading to 1.7 did not fix it.
In wired mode and 2.4gh it works perfectly.
I appreciate any information.

Thank you very much.

I’m also having the same problem. Tried resetting the keyboard/profile, upgrading firmware, different devices - but bluetooth pairing is basically bricked.

The response here suggest a hardware fault:

I have the same problem with the BT.  It started a week ago. 

In the first 2 minutes i can pair with win11, android, etc, but the BT signal is just blinking (the 1,2,3 numbers), and after the signal is lost, and just keeps blinking…

It is a Deathstalker V2 Pro TKL.

We are at least four of us.

I kindly ask Razer to investigate this incident.

Hi. I was having the same issue until I checked the user guide.

Try holding the ‘1’ or any profile button beside the main power slider button. When I held it for a few seconds, it showed up on my laptop’s BT list.

Thank You, but this is not your case.

The BT issue exists also when I want to pair with Android.

The first 2-3 minutes the BT works, but the led (1) blinks slow constantly. After the BT signal is lost and the led (1,2,3 keys) blinks slowly….

It is not OS related...

I started getting this issue as well a couple days ago. I noticed that the issue popped up when my work computer got updated to Synapse 4 while my personal computer was on Synapse 3. After digging a bit deeper, I noticed that there seemed to be issues sharing the profiles stored on memory between both computers. This is probably linked to the fact that there where changes to how the profiles are configured/stored.

Ultimately, this leads me to believe the issue isn’t hardware based but caused by some sort of corruption to the onboard memory state which doesn’t registered to which device the Bluetooth profile has been connected to.

I am also having this issue after trying all the usual fixes. Keyboard works fine otherwise, but the BT chips they sourced must be crap. I can’t connect to Windows via Bluetooth on two different PCs. Frustrating for Razer for sure. 

Same here. Brandnew PC, only cable works. PC 8 years old with a 10+ years old USB Bluetooth adapter.. works for days, then from one second to the other keyboard is gone. Not coming back even after resetting BT (removing the keyboard, trying to pair again, etc).

I gave up, this keyboard has no BT. What Razer calls BT is more like a random wireless something. Seems not a hardware fault but fail by design. Cannot believe I paid so much money for this thing..

Hello!

This is a hardware issue. They replaced my keyboard, the new is perfect. Please contact with them.

Thanks for the info. I’ll try this approach. Don’t like to create additional electronic trash, but if there is no other solution..

My one never worked. I did lots of tests using Chat GPT Plus and it ended saying that is hardware problems. I will try to contact the support (it is not easy) to see if they kswap my keyboard. Loosing faith on Razer.

Does your keyboard still under warrenty when you contact RAZER?

Earlier this week I ran into an issue with my Deathstalker V2 Pro TKL. After some research I found out the keyboard had entered Demo Mode on its own, without any action on my part.

Before I discovered the solution to disable Demo Mode, I had already contacted Razer Support in parallel. Their suggestion was to update the firmware to the latest version 1.7.0. I followed their advice — the update completed successfully, but it did not resolve the Demo Mode issue at all.

I then found the fix for Demo Mode myself and applied it — the keyboard started working again, but only partially. Since the firmware update, Bluetooth connectivity is completely dead. The keyboard is now only functional in wired USB-C mode, which defeats the whole purpose of buying a wireless keyboard.

This is particularly frustrating because the Bluetooth issue was directly caused by following official Razer Support advice. I now have a "wireless" keyboard that only works on a cable.

To make matters worse — the keyboard was received on April 16, 2025, registered on the Razer website with the receipt uploaded as proof of purchase, and came with a full manufacturer's warranty. I am now left with a broken device as a direct result of following official Razer Support instructions.
