Go into ur phone settings, security settings, phone and sim. Scroll down to lock code.
To change the code to ur own, select it, and it will ask for the default lock code which is 12345. Once confirmed, it will ask u for ur new code which can be
4 or 5 digits. Pick something u wont forget. Then it will ask u to confirm it.
Done.
Now if ur phone has an autolock feature, u can set it by selecting it and selecting user defined and set a time, like 10 or 15 minutes, up to u. Ur phone will lock after
that set time of inactivity. U will still be able to take calls, but need to put the code in to do anything else. Code will be requested each time u turn ur phone on.
Depending on ur nokia, u may have remote lock feature. With this, u set a password, and if ur phone is stolen and ur worried that it hasnt autolocked, u can send that
password to ur phone from any other phone by sms and it locks it.
U may also have the feature to have the phone lock if the simcard is changed and u can enable that too.
Finally, u have pin lock. This locks ur sim card, even if a theif takes it out and puts it in another phone, the code will be required to use ur sim.
To change the pin code, its the same as the lock code change, but the default code u need to put in first is different. Its usually 00000 but if that doesnt work, select
cancel, and call ur service provider, they will give u their sim pin default code, and after uv done that, select pin request on, and it will ask for a code every time u
turn ur phone on.
Its a good idea to make ur pin and lock code the same so u just enter them consecutively on start up
Hope this helps. [answer taken from Yahoo.answers]

I want to change phone lock code on T280i i have forgotten original code. i dont want to change sim lock code only phone lock


HI If you are asking for pin contact your service provider ,
he will give you a default pin .
If you try pin more than few predefined no of times your phone will ask PUK
code which can also be given only by your service provider which is specific for each and
every mobile number . Do not try PUK(new pin code) code many times or else your sim will be
blocked and you will need a new sim.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no.
Go to the nearest service outlet of your service provider they can also help you.
There is no other go than the above procedure only your service provider can give it nobody else
in this world nor any software.

Hope this helpout......

Tocco lite phone freeze deactivate fail


here is some info on PUK codes:

try taking battery and SIM out waiting 15 seconds and powering cell back on.

In your case I believe your SIM is now FROZEN or locked. You mostlikely will need to purchase a new SIM card.

A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

If the wrong PUK code is entered ten times in a row, the SIM card becomes invalid and you will need to purchase a new SIM Card. The phone will display "PUK blocked call operator".

N96 i forgot my lock code cannot open,hw?


Hi buddy there are 2 codes for N96 the LOCK Code and the PIN Code.

If you have not changed your LOCK code, the default number is 12345. The PIN Code is provided by your cellphone provider unless you have changed that too.

All Nokia LOCK code is always a 5-digit code, not 4 or 6-digits. So in case you changed your LOCK code to more than 5-digits, enter ONLY the first 5-digit of your LOCK code.

OR Try this:

Nokia *#7328748263373738# Resets the security code to default(ie,12345)

If that does not work then this applies:

The service provider cannot help you when the passcode has been changed from the default. It is not called a security code for no reason. You have 3 choices:
1. Replace the device
2. Send the device back to the manufacturer or take it to a shop to have the software flashed and reloaded
3. Start at 0000 and keep adding 1 to it (0000; 0001; 0002; etc) until you hit the right number

I hope this will help you otherwise I don't know. Plz vote for me.

Thanks.

Child put in random code and locked nuvi 260 gps

You can change the PIN on the unit by doing the following:
All Nuvi's excluding 3xx and 6xx
  1. Turn your device on
  2. Touch Tools
  3. Touch Settings
  4. Touch Security
  5. Touch On/Off under Garmin Lock
Within this section you can add or change a PIN.

When the Garmin security lock is set it locates the units current GPS location.
If you are trying to change the Garmin Lock and are not within the same location to where the Garmin Lock was set you will need to revert back to this GPS position.

Once at this position you will not be prompted to enter the PIN Code when starting the device up and can change the code as you please

Security code for Nokia 2100


The main code used in Nokia phones is :
#pw+(master code)+Y#
This code is able to check, activate or remove Sim card restriction (SP-lock).
Use the * key to get the p, + and w chars.
'Y' has to be 1,2,3 or 4 - depending of what lock you what to deal with.

#pw+1234567890+1# for Provider-Lock status
#pw+1234567890+2# for Network-Lock status
#pw+1234567890+3# for Country-Lock status
#pw+1234567890+4# for SimCard-Lock status

# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4

(master code) is a 10 digit code, based on the phones IMEI number.

Eg. To remove restriction on lock 1 type following code:
#pw+(master code)+1#
If you just want to check your phone use 10 random numbers Eg. 1234567890 as the (master code)
eg. To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#

Bypass the SP lock With a Nokia 16xx/21xx/31xx/51xx/81xx

1. Insert SIM card of different provider.
2. Turn on the phone and press the UP VOLUME key for 3 sec.
Then release it and the phone says PIN CODE?
3. Press the "C" key.
4. Then Press * and wait until it disappears and appears again, then press * one more time and 04*PIN*PIN*PIN#

The phone now says: PIN CODE CHANGED (or ACCEPTED) and the SIM card is accepted until you restart the phone again.
NOTE: On version 5.04 Nokia has removed this option !

I saw your reply phone lock


Your pin number is probably your sim code!
Check PUK
SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Are you sure it’s the Master code you need. Which is the one that you want?
Special Code/Service Provider Lock Code:
This code is required to allow a phone locked to a particular network's SIM cards to be used with a SIM card from another network. Orange and T-mobile lock handsets in this way, though O2 and Vodafone are beginning to lock PAYG and WAP handsets. The unlock code varies from individual handset to handset.
Blacklisting:
This is not a security code, but it works like one! To help combat mobile phone thefts, the networks share a database of the IMEI (International Mobile Equipment Identity) of mobile phones that have been reported stolen. Once a phone is on this list, it will not be allowed to use any of the networks.
This can be a risk if you buy a second-hand phone, because if it has been stolen, or if an unscrupulous seller makes an insurance claim after selling, the phone you bought in good faith may be permanently disabled.
Be very careful to check the source of a second-hand phone!
Voicemail Pin:
This is a code that you choose to secure the voicemail/answer phone service on your mobile phone account.
If you do not set a voicemail PIN, you may not be able to access voicemail from anywhere but your own mobile phone. In some cases, leaving the voicemail PIN at the default can let other people listen to or delete messages left for you. There may be a default code (3333 on Vodafone), but you should change it straight away!

Hi baddog27, There is one way to access your phone and that is: 

Block your sim by entering wrong lock code and then it will ask for the PUK code that you will get from your service provider. Enter that PUK code and your phone is unlocked. 
By this method you will not loose your data in your phone.
 

Thanks..
