How to Unlock a Locked Windows 10 Mobile with Forgotten PIN

Find My Phone feature on Windows 10 Mobile allows you to remotely lock your phone with a PIN of your own choice. As long as the phone has an active internet connection, you can reset your PIN lock remotely. If you never enabled Find my Phone feature, the only option is to reset your device. So let’s find out how you can Unlock a Locked Windows 10 Mobile with Forgotten PIN!!

Enable Find my Phone:

  • Settings > Update and Recovery > Find my Phone
  • Toggle the options which will save your device location periodically & more often.
  • Make sure you have a SIM in the phone, and it works.

How to remotely change the PIN

Let’s say you forgot your PIN, and have entered multiple times with no success. Windows 10 Mobile blocks you out, and sometimes even asks you to restart the phone before trying again.

  • Go to and select your device.
  • Click on Find My Phone. The next page gives you the option to Ring, Lock, and Erase.
  • Click on Lock. Here you can set a six-digit PIN, along with a message and an optional contact number.
  • Click on Lock again, and your phone should get locked with a new PIN.
  • Use the new PIN to unlock.

Interesting to note:

  • Instead of 4 digit PIN lock, Windows 10 Mobile now has six digit PIN lock, along with an option to use a number. Windows Phone 8.1 has four-digit PIN lock with only option to send a message.
  • The phone restarts once the new PIN is remotely set.

So the first thing I would recommend anybody when setting up their Windows 10 Mobile would be to enable Find my Phone feature, even if it’s not a full proof option to find your lost phone.

  1. Interestingly, ringing your phone works even if the SIM card is removed. But of course it has to be under power.
    The problem I have now: It’s ringing on my old phone (930) I have put aside as backup without SIM. How do I register my new phone (959XL), the same SIM and Microsoft account? I don’ see it under devices.

  2. I had my Windows 10 Mobile locked and didn’t remember the phone PIN. This was the only place were I found the solution that didn’t have to reset the phone. Thank you!

  3. So I followed the instructions, but it’s not giving me a new pin. It’s telling me to use the pin I forgot to lock into my phone

  4. I did exactly the article says: Proceeded with the Find my phone option selecting Lock option and it was requested to me to set a new PIN code. After doing so, entered it in the phone and everything was fine :-)
