double contact occur dur to copy of same contact from sim to handset or to handset to sim.go for contact select delete all and then sim1 r sim 2 after that enter security code(default:0000).

You have to enter the default security code
Default will be 0000 or 1234 or 12345 or 00000(For default code check user manual of user handset).
If these won't works somebody changed security code.
To reset security code you need to flash your handset

To flash you need *USB cable compatible with your handset *A C omputer *PC suite of your handset *Internet connection(Min speed 1Mbps)

To flash *Install the PC suite *Connect to USB *Open the PC suit *Select UPDATE PHONE SOFTWARE**
**Please don't disconnect while updation process

Try master reset code

The default security code is set to ?0000? and the
security code is required to delete all phone entries and to restore the handset to factory setting.

on your lg cookie go to menu> settings> phone settings> security> handset lock> choose "None"

you shoud know your secuity code though :)

The default lock code (security) is 0000. and default, PIN1 is 1111, and PIN2 is 2222
If you need further help let me know. If you get it wrong enough you will be asked to enter PUK code. Then you only need to call up your provider and they will assist you.
