Lock Code; Pin Codes; Puk Codes - Nokia 6120 classic User Manual

Lock code

The lock code (5 digits) helps to protect your phone against unauthorized
use. The preset code is 12345. Change the code, and keep the new code
secret and in a safe place separate from your phone. You can change the
code and set the phone to request the code.
If you enter an incorrect lock code five times in succession, the phone ignores
further entries of the code. Wait for 5 minutes, and enter the code again.
When the device is locked, calls may be possible to the official emergency
number programmed into your device.

identification number (UPIN) code (4 to 8 digits) help to protect your SIM card
against unauthorized use. The PIN code is usually supplied with the SIM card.
The PIN2 code (4 to 8 digits) may be supplied with the SIM card and is required
for some functions.
The module PIN is required to access the information in the security module.
The module PIN is supplied with the SIM card if the SIM card has a security

PUK codes

The personal unblocking key (PUK) code and the universal personal unblocking
key (UPUK) code (8 digits) are required to change a blocked PIN code and UPIN
