Synchronizing 2 database tables , problem with primary key

Hello , i want to synchronize 2 tables with this code

Code:

---

            SqlConnection sqlConnLocal = new SqlConnection(stgProjectConn);
            SqlConnection sqlConnRemote = new SqlConnection(stgRemoteConn);

            SyncOrchestrator agent = new SyncOrchestrator();
            string scopeName = "test";
            SqlSyncProvider sqlProviderLocal = new SqlSyncProvider(scopeName, sqlConnLocal);
            SqlSyncProvider sqlProviderRemote = new SqlSyncProvider(scopeName, sqlConnRemote);
            SqlSyncScopeProvisioning scopeProvisionLocal = new SqlSyncScopeProvisioning(sqlConnLocal);
            if (!scopeProvisionLocal.ScopeExists(scopeName))
            {
                DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription(scopeName);
                scopeDesc.Tables.Add(SqlSyncDescriptionBuilder.GetDescriptionForTable("mytable", sqlConnLocal));
                scopeProvisionLocal.PopulateFromScopeDescription(scopeDesc);
                scopeProvisionLocal.SetCreateTableDefault(DbSyncCreationOption.Skip);
                scopeProvisionLocal.Apply();
            }
            SqlSyncScopeProvisioning scopeProvisionRemote = new SqlSyncScopeProvisioning(sqlConnRemote);
            if (!scopeProvisionRemote.ScopeExists(scopeName))
            {
                DbSyncScopeDescription scopeDesc = SqlSyncDescriptionBuilder.GetDescriptionForScope(scopeName, sqlConnLocal);
                scopeProvisionRemote.PopulateFromScopeDescription(scopeDesc);
                scopeProvisionRemote.Apply();
            }
            agent.LocalProvider = sqlProviderLocal;
            agent.RemoteProvider = sqlProviderRemote;

it works and it synchronize the data but i have one problem .

My 2 tables structure is ID,Name,Surname. (ID is primary key , Auto increasement)

Table1 values

1 myname mysurname
2 myname2 mysurname2
3 myname3 mysurname3

Table2 values

My code will add rows with id 4 and 5 to table1 but the 1st row (myname5 mysurname5) will replace the table1 1st row (myname mysurname) , i want to add it as new. is that possible ? i dont want to loose table1 1st value
