We’ve all been there — you grab your iPhone, try to unlock it, and then… nothing works. Maybe you forgot your passcode. Maybe your kid typed the wrong code too many times. Or maybe you bought a second-hand iPhone that’s still locked with someone else’s info.
It feels frustrating, right?
Luckily, you don’t have to panic or wait for hours for help. There’s an easy tool that can unlock your iPhone without needing a password. It’s called 4uKey, and it’s made by a trusted company called Tenorshare. In this article, you’ll learn exactly how it works and how to use it — step by step.
What Is 4uKey and Why Do People Use It?
4uKey is a simple program that helps you unlock your iPhone if you’re locked out and don’t remember the password. It works for all kinds of screen locks — whether it’s a 4-digit passcode, 6-digit code, Face ID, or Touch ID.
People use 4uKey when:
-
They forget their iPhone or iPad passcode
-
The phone says “iPhone Unavailable” or “iPhone Disabled”
-
The screen is locked after too many wrong tries
-
They bought a used device with a lock still on it
What’s great is that 4uKey doesn’t need any tech skills. It guides you with easy steps. You just follow the on-screen instructions, and in a few minutes, your iPhone is unlocked.
When You Might Need to Unlock an iPhone Without a Password
Let’s say you bought a second-hand iPhone online. It looks perfect — but when you turn it on, it’s locked with the old owner’s Apple ID. You can’t use it, and they’re not replying.
Or maybe you changed your password last week, and now you can’t remember it. You try again and again. Suddenly, your iPhone is disabled. Now what?
Here are some real-life examples when 4uKey comes in handy:
-
You forgot your passcode completely
-
Your child or sibling tried the wrong code too many times
-
You want to reset your phone but can’t remember the screen lock
-
You bought a used phone that’s still locked with someone else’s Apple ID or MDM profile
In all these cases, 4uKey can help you unlock the iPhone without needing the password.
Can 4uKey Really Unlock Any iPhone?
Yes — 4uKey is designed to work with almost every iPhone, iPad, and iPod Touch, from older models to the latest ones in 2025.
It supports:
-
All types of screen locks – 4-digit, 6-digit, Face ID, and Touch ID
-
Most iOS versions, including iOS 7 to iOS 16 and beyond
-
Latest models, like iPhone 14 and the newest iPad Pro 2023
It doesn’t matter if your phone is old or new — as long as it’s an Apple device, 4uKey can help remove the lock.
This makes it one of the most trusted unlock tools in the market. It’s especially helpful if you want a fast and simple way to unlock your iPhone without a passcode.
How to Download and Install 4uKey on Your Computer
Getting started with 4uKey is super easy. You don’t need to be a tech expert at all.
Here’s how you can do it:
-
Visit the official Tenorshare website
-
Choose the Free Download button
-
Install it on your Windows PC or Mac
-
Open the program and you’ll see a clear menu with simple options
4uKey works on:
-
Windows 11/10/8.1/8/7
-
macOS 13 and earlier
After installing, you just need a USB cable to connect your iPhone or iPad to your computer. That’s it. Now you’re ready to begin the unlocking process.
Step-by-Step: How to Unlock iPhone Without Password Using 4uKey
Let’s walk through the steps together — it’s really that easy.
Step 1: Open 4uKey and Click “Start”
Once you launch the program, you’ll see an option that says “Unlock Screen Passcode.” Click it.
Step 2: Connect Your iPhone
Use a USB cable to plug in your iPhone. Make sure your internet is working properly. Click Next to continue.
Step 3: Download Firmware
4uKey will now find the right software version (called firmware) for your iPhone. It will download it automatically.
Step 4: Start the Unlock
After the firmware is ready, you’ll see a button that says “Start Remove.” Click it, and the unlocking will begin.
Step 5: Wait a Few Minutes
Now just sit back and relax. In a few minutes, 4uKey will unlock your iPhone without the password. When it’s done, your phone will restart — unlocked and ready to use.
That’s it! Just a few clicks and you’re back in.
What Happens After You Unlock with 4uKey?
Once your iPhone is unlocked, it will go through a quick reset. This means all your old data — apps, photos, messages — will be erased, just like a brand-new phone.
If you had a backup saved in iCloud or iTunes before you were locked out, you can easily restore your data after the unlock. If not, you’ll need to set up the iPhone from scratch.
But don’t worry. After unlocking, your iPhone works just like normal again. You can create a new passcode, sign in with your Apple ID, and start fresh.
Can 4uKey Remove Apple ID or Screen Time Code?
Yes, 4uKey can also help if you’re stuck with a forgotten Apple ID or Screen Time passcode.
Let’s say you forgot your Apple ID password, and now your phone is locked under it. 4uKey has a feature to remove the Apple ID from your device — but only if Find My iPhone is turned off. If it’s on, the data may be lost.
It can also remove Screen Time restrictions. Maybe you set a code to limit app usage, but now you can’t remember it. With 4uKey, you can remove it in seconds, and your data stays safe.
These extra features make 4uKey even more helpful, especially for families with kids or shared devices.
Bypass MDM Lock on iPhone or iPad with 4uKey
MDM stands for Mobile Device Management. It’s often used by schools or companies to control what their devices can do.
If you bought a used iPhone and see an MDM lock (asking for remote management login), don’t worry. 4uKey can bypass this lock, too.
Just connect the device and choose the “Bypass MDM” option. The process is very simple and takes only a few minutes. After that, the MDM profile will be removed, and the iPhone will be fully yours.
But here’s a tip: Don’t restore from iCloud backup after removing MDM. That could bring the MDM profile back. It’s better to restore from a local computer backup or start fresh.
Is It Safe to Use 4uKey to Unlock iPhones?
Yes, 4uKey is safe to use — as long as it’s your own device or you have permission to unlock it.
It doesn’t steal your information or collect personal data. You’re in full control the entire time. Also, every step of the process is clearly shown on the screen, so nothing is confusing.
But remember, unlocking your device will erase the data unless you’re just removing Screen Time or bypassing MDM. So if you can, back up your iPhone first.
And if your iPhone has iCloud Activation Lock, 4uKey cannot remove that. You’ll need a different tool (like Tenorshare 4MeKey) or help from the original owner.
Things to Keep in Mind Before Using 4uKey
Before you begin, here are a few helpful tips to avoid surprises:
-
Make sure your device is fully charged
-
Backup your data if possible — especially through iTunes
-
If your iPhone has Find My iPhone turned on, removing Apple ID might erase your data
-
Don’t use this tool for illegal reasons — it’s only meant for your own devices
Also, know that once the Apple ID is removed, you shouldn’t try to update the device through iTunes. That might lock it again. Instead, update through the phone itself or with care.
How Much Does 4uKey Cost?
You can download 4uKey for free to try it out and explore the features. But to unlock your iPhone fully, you’ll need a paid plan.
Here are the prices in 2025:
-
Monthly Plan: $35.95
-
Yearly Plan: $55.95
-
Lifetime Plan: $75.95 (best value)
Each license lets you unlock up to 5 devices using 1 computer. You also get free updates and support during your plan.
If you’re someone who unlocks devices often — maybe for family or clients — the lifetime plan is a smart pick.
Conclusion
If you’re locked out of your iPhone and don’t know the passcode, Tenorshare 4uKey is one of the easiest and safest ways to unlock it.
It works for many situations — screen lock, forgotten Apple ID, MDM lock, and more. It’s also fast, user-friendly, and doesn’t need tech knowledge.
But like any tool, it has limits. It can’t remove iCloud Activation Lock unless you use a different product. And it can erase your data if you didn’t back up.
Still, if you need a quick, simple fix — and want to unlock your iPhone without a password — 4uKey is a great choice. Just follow the steps, read the tips, and your iPhone will be back in your hands in no time.
