Here's the quick-fire solution to renaming your SQL Server database:

-- Hey! Pay attention! Single user mode is coming. No trespassing, please.
ALTER DATABASE CurrentName SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

-- Now, in the silence of single mode, let's give it a new name.
ALTER DATABASE CurrentName MODIFY NAME = NewName;

-- Let's open the doors again. Welcome back, users!
ALTER DATABASE NewName SET MULTI_USER;

Turn the database access to SINGLE_USER, rename it using MODIFY NAME, and then regain normalcy by switching back to MULTI_USER. Boom! You've done it!

Before diving in, make sure you have the privy rights to alter your database. Also, remember that an exclusive lock on the database is needed, only possible when every other user is disconnected.

Pre-requisites

Before renaming a database, ensure:

You have a backup. There's no harm in being extra safe!
The database will be unreachable during the renaming process. So, schedule during off-peak hours.
Database lock status must be verified before proceeding. You don't want to barge into an ongoing transaction!

Facing the "Msg 5030" error? This can be resolved by setting your database to SINGLE_USER mode to gain an exclusive lock.

Manual (non-script) methods

Use SQL Server Management Studio (SSMS): Instead of T-SQL, renaming can also be done by clicking on the database, going to Properties, and editing the name. Yes, it's as straightforward as it sounds!
sp_renamedb can also be used but hey, it's deprecated now! ALTER DATABASE MODIFY NAME is the new cool kid on the block!

Potential pitfalls

Here are some do's and don'ts while renaming:

Forgetting to sever current connections to the database can prevent the renaming operation.
Skipping the change verification step can spell disaster. Always verify via SSMS or sys.databases to confirm success.
Ignoring dependencies: Remember to keep your scripts and jobs updated with the new database name.

Challenges & How to tackle them

Even smoothly planned processes get a bit rocky. Here's your rock climbing guide:

Encountered a locked database? Use sp_who2 or DMV sys.dm_exec_requests to identify processes and KILL <SPID> to terminate what's necessary. But tread with caution!
Denied permissions? Check your roles. To alter the database, you need membership of the db_owner role or ALTER permissions on the database.
Dealing with automation scripts can be hairy but remember to update them with the new database name post-rename.
