Son changed my security code somehow dont know how to change it or bypass it so i can use my phone

call your service provider they should be able to give it to you, or they may have you enter a code in 10 times until you get the puk code message and they can give that to you. Dont try to enter the code in more than 10 times without calling your provider, you can accidentally lock it to the network and then not be able to use it.

My son forgot his security code for his motorola v360. pls help!!

I think this will help....

codes & passwords
Your phone’s 4-digit unlock code is originally set to 1234.
The 6-digit security code is originally set to 000000. If your
service provider didn’t change these codes, you should
change them:
Find it: Press M > Settings > 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 M and enter your 6-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
