I need a numeric passkey for Motorola for motorola LG GR500 for samsung SGH-i677

try code online sites and Unlock it.

when turning on your bluetooth device hold the power button down,for 8 to 10 seconds this usually puts the bluetooth inn pairing mode,then you have to enter a pin pairing code ,motorola and most other bluetooth manufactures use a 4 digit pin pairing code,motorola is as follows 0000,1234, and the others incase they dont work,are 9999,1111,try them in that order hope this helps

Motorola uses the folling pin codes 0000,1234,if one of these dont work there are two more that are universal 9999,1111,i hope this helps

First try these codes 0000,1234,****

or If you enter wrong password for more then 5 times,it ll ask you to enter the puk number....now call your customer care and
get the puk number...enter the puk number in the space given for password....thats it...problem is fixed
If you had locked your mobile then update the formware all saved passwords will be deleted

0000

try 0000
or 000000
or 1234
or 123456

when pairing a handsfree device to your phone the typicaly generic passcode is 4 zero's (0000)

took me a minute, but i figured it out on mine.  Without using the alt button, type 0000 then hit enter.  Hopefully this will work for you as well.

the default code should be 0000

Try 0000
