If your iPhone shows “Security Lockout”, it means the phone is fully locked and iOS is blocking passcode entry. This usually happens after too many incorrect passcode attempts (or repeated tries after the “iPhone Unavailable” timer).
In most cases, you can’t “wait it out” anymore. The reliable fix is to reset (erase) the iPhone, then restore your data from a backup.
Fix iPhone Unavailable Without Computer
Quick answer (do this first)
- If you see “Start iPhone Reset” on the screen, use it (it’s the safest on-screen route). Apple notes you can only reach this reset flow if you have an active cellular/Wi-Fi connection and previously enabled Find My.
- If you don’t see the reset option, use Recovery Mode on a computer to restore the iPhone.
- If you recently changed your pass code (within about 72 hours), you might be able to use your old password one time via Password Reset.
iPhone Unavailable: How Long Does It Last?
Security Lockout vs iPhone Unavailable (don’t mix them up)
- iPhone Unavailable usually shows a timer (“Try Again in…”). You can often unlock by waiting and entering the correct passcode once.
- Security Lockout usually means passcode entry is blocked, and reset is normally required.
What to do when you see iPhone Unavailable
Why your iPhone shows “Security Lockout”
Most common reasons:
- Too many wrong pass code attempts
- Someone kept trying after the timer (kids, pocket taps, etc.)
- Face ID/Touch ID failed repeatedly and password attempts went wrong
- A damaged screen registering ghost touches
The safest fix path (recommended)
Step 1: Check if “Start iPhone Reset” appears
If your Security Lockout screen includes “Start iPhone Reset”, follow the on-screen instructions. Apple’s guidance notes you’ll likely be asked to enter your Apple Account password to sign out.

Step 2: Make sure your iPhone has internet
This matters because Apple notes the Security Lockout reset flow depends on having an active cellular/Wi-Fi connection and Find My being enabled.
Try:
- Connect to a trusted Wi-Fi network (if possible)
- Insert SIM / enable mobile data (if it was off)
Step 3: If reset option still doesn’t show, use Recovery Mode (computer)
If on-screen reset isn’t available, Apple’s official recovery method is to reset using a computer (Recovery Mode) and then restore from backup.
Important: Recovery Mode erases the iPhone.
Can you fix Security Lockout without erasing data?
Usually, no. If you forgot the password and reached Security Lockout, Apple’s guidance makes it clear that accessing the device again normally requires a reset, which erases data currently on the device.
The only “data-safe” scenario is:
- You actually remember the correct pass and the phone is not in a state that blocks pass code entry (more common with “Unavailable” than “Security Lockout”).
Special case: You changed your passcode recently (iOS 17+)
If you changed your passcode and forgot the new one, Apple describes Passcode Reset that can let you use the previous passcode within a limited window (commonly 72 hours).
If you see a “Forgot Pass?” path, follow it and look for the option to use the old pass.
After you reset: restore and prevent it happening again
- Restore from iCloud backup or a computer backup
- Set a passcode you will remember (and store it safely)
- Keep Find My enabled (helps with recovery options)
FAQs
Does Security Lockout go away after some time?
Usually no. It typically indicates a state where passcode entry is blocked and reset is required.
Why don’t I see “Start iPhone Reset”?
Apple notes the reset path depends on having an active network connection and Find My enabled beforehand.
Will resetting remove Activation Lock?
No. After reset, you’ll still need the Apple Account login if Activation Lock is enabled.
