You've been there. You grab your DualShock 4, head over to a buddy's house for some Mortal Kombat or FC 26, and suddenly your controller feels like a brick. It glows white, pulses for a second, and then just dies. It refuses to talk to the other console. Honestly, it’s one of those minor tech frustrations that feels way more complicated than it actually is.
Syncing a controller to a different system isn't just about pressing buttons and hoping for the sake of your K/D ratio. The PS4 uses a very specific handshake protocol. If you don't nail that handshake, you're stuck playing "pass the controller" on a single gamepad all night.
The Physical Link is Everything
Most people try to use Bluetooth right away. Don't do that. It rarely works for a fresh pairing between a used controller and a "foreign" console.
The most reliable way to connect PS4 controller to another PS4 is the old-school USB method. But here is the kicker: not all cables are created equal. I’ve seen dozens of people pull a random micro-USB cord out of a junk drawer—maybe one that came with a cheap rechargeable fan or an old Android phone—and wonder why the light bar won't turn blue.
Those are "power-only" cables. They’ll charge the battery, sure, but they won't transmit data. You need a data-sync cable. If you still have the original black Sony cord that came in the box back in 2014 or whenever you bought the thing, use that. If not, look for a cable labeled for data transfer.
Plug one end into the front of the "new" PS4 and the other into your controller. Press the PS button in the center. The light bar should change from a slow orange pulse (charging) to a solid color. Once it's solid, you're synced. You can now unplug the cable and play wirelessly. It’s that simple, yet so many people miss the "data cable" nuance and think their Bluetooth chip is fried.
Dealing With the Bluetooth "Device Full" Headache
Sometimes, you’ll try to connect and the console just rejects you. This usually happens on consoles that have seen a lot of action—think dorm rooms or houses with five roommates.
The PS4 can technically remember a lot of devices, but it has a limit on active pairings. If you’re trying to connect PS4 controller to another PS4 and it keeps failing even with a cord, you might need to dive into the settings of the host console.
Navigate to Settings, then Devices, and finally Bluetooth Devices. If you see a list of ten "DualShock 4" entries and half of them aren't even in the room, start deleting them. Highlight an old entry, hit Options, and select Forget Device. This clears the "cache," so to speak, and makes room for your controller to register properly.
The Wireless "Share and PS" Trick
What if you don't have a cable? Maybe you're at a gaming lounge or your friend is a minimalist who hides all their cords. You can try the wireless pairing mode, though it's finicky on older firmware versions.
- Turn the controller off completely.
- Hold down the Share button and the PS button simultaneously.
- Keep holding until the light bar starts double-flashing white. This is "Pairing Mode."
- On the PS4 you want to connect to, you’ll need a controller that already works to go into Settings > Devices > Bluetooth Devices.
- Your "new" controller should appear in the list. Select it.
It’s a bit of a Catch-22 because you need a working controller to navigate the menus to add a second one wirelessly. If you’re trying to set up a console for the first time without a cord, you are basically out of luck. Buy a cable. Seriously.
When the Controller Refuses to Cooperate (The Reset Hole)
Sometimes a controller gets "stuck" on its home console. It’s like it’s homesick. No matter how many times you plug it into the other PS4, it just won't pair.

On the back of the DualShock 4, near the L2 trigger, there is a tiny, tiny pinhole. That is the hard reset button. Find a paperclip or a SIM tool. Push it in there for about five seconds while the controller is on. The controller will die instantly. This clears the internal pairing memory.
Once you've done this, try the USB cable method again. This "hard reboot" fixes about 90% of syncing issues that people mistake for hardware failure.
Why Does This Even Happen?
Sony designed the PS4 to be secure. They didn't want controllers accidentally turning on consoles in the next apartment over. Because of that, the Bluetooth "ID" of the controller is locked to the last motherboard it shook hands with.
When you move to another system, that ID doesn't match. The USB cable acts as a bridge to exchange the new encryption keys. It’s not just "charging"; it’s a digital introduction.
Remote Play and PC Conflicts
A weird edge case I see a lot involves people who use their controllers on PCs or Macs. If you’ve been using your PS4 controller to play Elden Ring on Steam, your controller is now looking for your PC's Bluetooth signal.
If your PC is in the same room while you're trying to connect PS4 controller to another PS4, your controller might keep trying to "talk" to your computer instead. Turn off your PC's Bluetooth or "Forget" the controller in your Windows/macOS settings before you try to sync it back to a console. The DualShock 4 is surprisingly loyal to the last thing it was connected to, and it will prioritize a PC signal over a new PS4 signal if it recognizes the PC.
Specific Steps for Local Multiplayer
If you are connecting a second controller just for a quick session, remember that the PS4 treats every controller as a "User."
- Connect via USB.
- Press the PS button.
- The screen will ask "Who is using this controller?"
- Do not select the same profile as Player 1. If you do, it will just switch the control of that profile to your gamepad and kick the other person off.
- Select "New User" or "Guest."
Selecting "Guest" is the fastest way, but keep in mind that guest data (like trophies or save files) disappears the moment you log out. If you're playing a long campaign together, your friend should actually log into their PSN account on your machine.
Actionable Troubleshooting Checklist

- Check the cable. If it’s thin and flimsy, it’s probably a charging-only cable. Try a thicker one or the one that came with a high-end smartphone.
- The 5-Second Reset. Use a paperclip on the back pinhole. It’s the "did you turn it off and back on" of the controller world.
- Full Power Cycle. Sometimes the PS4 itself has a glitched Bluetooth stack. Turn the console completely off (not Rest Mode), unplug the power cord for 30 seconds, and then try the USB sync.
- Check for Interference. Move metal objects or large speakers away from the front of the PS4. It sounds like superstition, but 2.4GHz interference is real.
Connecting a DualShock 4 to a different system is ultimately a matter of hardware communication. Use a data-capable cable, reset the controller's memory if it’s being stubborn, and ensure you aren't fighting with a nearby PC for the Bluetooth signal. Once that solid blue or red light stays on, you're ready to go.
