I got a Nokia 6230,i never change security code,but now it will not accept my code,can you help

My head set had another pin code other than 0000 when I recieved the unit which made it dificult to connect. I learned how to reset it to the default pin of 0000 which allowed me to sync it with my phone. After using it for a month or so my phone requested the pin again.I entered 0000 and once again would not accept the pin. I had to retore the default pin again and it works just fine. Here are the instructions. Plug your vbt185z into the wall charger and while connected press down and hold the center blue button untill the light comes on.(about 30 seconds)Unplug the the ear piece and turn the unit on.Now enter pin 0000 and your phone should accept the pin.

Please follow the instructions carefully! Following are the 12-point instructions to unlock your Samsung E250 phone:
1. First do a CUSTOM RESET by tying in:
*2767*2878#
(Phone may display foreign language – don't worry! The last digits after the * will appear as - - - -; this is normal)
2. Turn off your phone
3. Take the battery and SIM out of the phone
4. Take a wrong network SIM (a SIM the phone does not currently accept) and insert it ONLY HALF way in, so when you turn on the phone it won't detect the SIM. Very important so the phone won't ask for network password and will show "Insert SIM" message.
The process of inserting only half of the SIM. I advice you to take care and do it with a soft approach as you might not have done this before.

5. 2. Now put the battery in carfully behind the protruding SIM card and switch the phone on. The phone must show "Insert SIM" message.
6. 3. Without turning off the phone, now push the SIM card all the way in, at this stage the phone must continue to display the "Insert SIM" message with the WRONG SIM inside.
7. Now make a FULL RESET by typing: *2767*3855#

9. Change the NCK password to 8 zeros by typing: *7465625*638*00000000*00000000#
8. The phone should reboot working with "wrong" SIM inside. (Do not turn off the phone)
10. Disable network lock by typing: #7465625*638*00000000#
12. Check this is done with *#7465625#
If your phone is not unlocked please retry the above ensuring all steps are followed to the letter, 9 out of 10 people who have problems have made a simple error and find that when they repeat all the steps it works.

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.
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.

For mathyn IMEI 010972008260174 Mastercode 5255056051
For mc hot IMEI 359838011209921 Mastercode 1600246040
For Guest IMEI Type *#06# to get it. Mastercode ??????????
For emanuelgaby IMEI 354528013559796 Mastercode 7367245612

This is the code needed to reset the Security code, nothing else, and it’s for your phone only. You type in the security codes (any) until the phone request the Master code; when it does, leave your phone still, don’t use it for 15 minutes, then type in the Master code.
