问题
I am in the process of transitioning us from an MSAccess backend to a SQL Server back end.
Without really considering keywords our plan has an Admin, Order and Address schema.I have always read and been taught that you should never use keywords as schema, function,stored procedure, etc. names and that doing so will really hose you.
If I plan to make it standard practice to always explicitely define my schema (E.G. [Admin].CompanyInformation) then is using a keyword an issue?

Once again, qualifying your object names with the schema is NOT related to the use of reserved words as identifiers. You will still encounter a problem using a reserved word as a name even if you qualify it with the schema name. Example:
set nocount on;
use tempdb;
go
create table dbo.[table] (id int not null);
print 'creating dbo.table as a table';
go
-- the next two statements fail
select * from table;
select * from dbo.table;
go
print '';
print 'select from dbo.[table] works**';
select * from dbo.[table];
if object_id('dbo.table') is not null
drop table dbo.[table];
go
So - yes you should use the schema name. And yes - you should avoid the use of reserved words as object names. Doing the former does not negate the need to do the latter. And there are additional rules for object names that you should know - the rules for regular identifiers are https://docs.microsoft.com/en-us/sql/relational-databases/databases/database-identifiers.
And even if you choose to NOT follow the rules, you will probably use software that you did not develop and that was not written carefully - which will fail to work correctly when it encounters an object name that is not a regular identifier. And THAT reason is the best reason for adhering to the rules for regular identifiers (one of which is to avoid using reserved words as names).

No, this not an issue if you write [Admin] (not Admin).
P.S. Anyway you should always excplicetly define your schema because default schema is usually dbo
