Security set up

Im assuming its a samsung phone
Samsung cell phones come with many security features.
In addition to the common feature of preventing calls after a period of inactivity, some Samsung phones also allow you to prevent others' use of your phone's SIM chip and access to your files.
One password unlocks the various locks, except for two other passwords used for the SIM chip. The syntax of the menu items to click to reset a password differ somewhat between Samsung models but you can figure out roughly how to apply instructions for one phone to another.

1
Lock the phone from making calls by clicking "Start" or "Menu," "Security Settings" (or "More" and then "Security"), and "Phone Lock" or "Device Lock."
Change the password by clicking "Start" or "Menu," "Security Settings," and "Change Password." Then enter a new password.

2
Set the phone to work only with the current SIM chip by clicking "Menu," "Security Settings," and "SIM Lock."
Enter a new password when prompted.

3
Prevent unauthorized use of your SIM card by clicking "Menu," "Security Settings," and "PIN Lock." Type a new PIN when prompted.
4
Prohibit access to your files, messages and contact list by clicking "Menu," "Security Settings," and "Privacy Lock."
Enter the password from Step 1 when prompted to unlock access.
Reset the file lock/messages/contact password by resetting the phone lock password, as in
Step 1

What is the Phone brand and model?
You can reset the Phone from Phone lock code or security code Using the master reset code,if the Phone is Nokia or Alcatel Phone means You can reset the Phone easily....you can get the master reset code from here
Superunlockcodes.com and reset it.....i reset my Nokia 6600 from the security Lock.
You can try Default code for Nokia 1234 or 0000 If it not works means You can get the Free master reset code there and reset it...For other Brand You can get the master reset code from service provider.....

Do a hard reset. Its very simple just press *#7370#.
Then it requests for the security key which is 12345 by default or enter your security code if you have changed the security code..
Please note that all the data on your phone will be deleted so kindly make a back up.

If it is the phone lock code, your phone must request for the PUK code, you can have it at the pack of your sim card when you bought it. if the PUK is blocked, you need to change your sim card (default cade for new sim is 1234) or contact your operator if they can still activate it for you.

if it is the security code, you can follow this link below to reset your phone to factory setting:

hi there,
call the customer service of your service provider ( O2 )....they will set up message center number on your phone , the one that you have might be incorrect...your mobile operator will send you sim updates that will refresh the settings ....and then you will get the text message options
cheers

usually your able to go into the menu and the either options or settings and click on security! but some phones are so dang complicated. lol here is what ive found its a razr 2 v9 right?its from the motorola website


codes & passwords
Your phone’s four-digit unlock code is originally set to
1234. The six-digit security code is originally set to
000000. If your service provider didn’t change these
codes, you should change them:
Find it: s >wSettings > Security > New Passwords
You can also change your SIM PIN or call barring
passwords.
If you forget your unlock code: At the Enter Unlock Code
prompt, try entering 1234 or the last four digits of your
phone number. If that doesn’t work, press s and
enter your six-digit security code instead.
If you forget other codes: If you forget your security
code, SIM PIN code, PIN2 code, or call barring
password, contact your service provider.
lock & unlock phone
You can lock your phone to keep others from using it.
To lock or unlock your phone, you need the four-digit
unlock code.
To manually lock your phone: Presss>
wSettings > Security > Phone Lock > Lock Now, then enter
your four-digit unlock code.
To automatically lock your phone whenever you
turn it off: Presss>wSettings > Security > Phone Lock >
Automatic Lock > On, then enter your four-digit unlock
code.

You can't change the memory for your text messages. The LG Cookie can store up to 500 messages on the internal memory.

In terms of locking your messages, you can lock the handset but you will need to do this proceedure every time you want to lock people out of your mobile.

Menu > Settings > Phone Settings > Security Settings > Handset lock

We hope this helps!
