A phone lock or security code on most Samsung handsets can be overridden by performing a full reset on the device. This will set the security codes on the handset back to the default eight zero's (00000000).
Important: This reset restores the original factory settings and will erase all downloaded content, including ringtones, images, programs, and contacts stored in the internal memory. It does not erase data stored on the SIM card or memory card (if available). Make sure you have backed up contacts, calendar appointments, and other data before continuing.
1. Power off the handset
2. Remove the battery
3. Remove the SIM card
4. Reinsert battery ONLY
5. Turn handset on
6. At the Insert SIM prompt screen enter the following code: *2767*2878#
NOTE: If using a handset that was released after July 2009 use this code: *2767*3855#
7. The handset should display E2P custom reset
8. Power off handset
9. Reinsert SIM card
10. Power on handset
11. The phone should be unlocked
NOTE: If you didn't get a E2P custom reset or a Full reset message on the handset your Samsung model may need an MCK code. You will have to call technical support for this code. Please have your IMEI number ready to expedite the process for this code. Your IMEI number is located on a label on the back of the phone,under the battery.
