First of all you can try to get a hold of verizon and see if they will give you the number to the phone then you will know the lock code....If they have changed the number simply dial *228 and program the phone and lock code will go back to the last four of the number....
Ok, well my idea might take a while to do but since the lg env has a four diget code number you could start from 0000 and work your way up. For example: 0000, 0001, 0002, 0003, and so on. My friend sold me a stolen env touch and I wanted to get into the security section but It was locked and the could not find the code but I tried the method above and luckily the code was 0000 so I finally got in and restored the phone, any way that is a suggestion but if it means a lot to you should try this.
