Are you trying to open MDB or ACCDB database file but getting a “Database is locked” or similar message? This issue mainly arises when another user has opened the file, an Access lock file remains after sudden shutdowns, or users do not have permissions to access the database. So, the Microsoft Access database locked error can be fixed by closing active sessions, checking the file or folder permissions, or deleting the .mdb or .accdb database file.

The exact solution depends on the scenario which a user is facing. A protected database file can stop you from opening, modifying, and analyzing important details such as tables or other objects. So, in the following guide, we will explain why the error happens, how to fix it step-by-step, and how to stop it from coming back. Now, let’s begin the discussion.

What Happens When MS Access (MDB/ACCDB) Database is Locked?

When you face an Access database file locked error, it restricts users from opening, editing, reading, and analyzing the database. This issue is more common in multi-user environments where several people access the same MDB or ACCDB file. Sometimes, the database may open in read-only mode, while in other cases, it may show locking or permission-related issues. A locked file can cause various problems that are explained below:

Unable to open database: Access will prevent users from opening .mdb or .accdb database files normally.
No Modifications Allowed: Making changes in tables, queries, forms, reports, & modules is completely restricted.
Read-Only Access: This allows users to only view database but cannot edit, add, or delete records.
Shared Access File Issues: When another user or an active session is going on, the Microsoft Access database locked error will occur.
Permission-Related Errors: If there are no file or folder permissions, this will prevent you from accessing MDB and ACCDB files.
High Risk of Data Inaccessibility: If the database remains inaccessible, you will need to repair the file to regain access.

Overall, before attempting manual or automated fixes, back up the original MDB or ACCDB database file. This will help users to protect the database while you try different methods.

Manual Ways to Fix “Microsoft Access Database Locked” Error

Several manual approaches can help users to resolve “Access database file locked” issue, depending on what is causing the database to remain locked. So, let’s understand each method in detail.

Fix 1: Close All Active Sessions of MS Access

If the database is open on a different computer or in another Access window, then this error is common. By closing all the sessions, users are unable to unprotect Access database file quickly. Now, follow the steps given below:

Ask other users to close Access MDB or ACCDB files.
Close MS Access on your machine.
Now, wait for a few minutes and reopen the database.
Lastly, check whether you are allowed to modify the file.

Fix 2: Delete the Access Database Locked File

Microsoft Access generates an .ldb file for MDB and .laccdb for ACCDB databases when they are opened. If the locked file remains after the sudden shutdown, it may cause locking errors. Follow the step-by-step instructions:

Close MS Access on all PCs.
Open the file or folder that contains the database.
Locate the desired file and create a backup.
Now, delete the lock file if no user is accessing it.
Lastly, reopen the .mdb or .accdb file.

Fix 3: Check & Verify Folder Permissions

If your account does not have permissions or if you don’t have the correct credentials to access the file, this will restrict you from opening it or making changes. Here are the steps to follow:

Right-click the database file and choose Properties option.
Now, open the Security tab and verify whether you have permissions or not.
Finally, apply the required permissions and reopen the MDB or ACCDB file.

Fix 4: Open MDB/ACCDB Database File in Exclusive Mode

Opening the Access file in Exclusive Mode provides your Access session with exclusive control for the database file. This can help to resolve the “Microsoft Access database locked” error caused by other active connections. Now, follow these quick steps:

Open MS Access and navigate to File > Open > Browse feature.
Choose the Access database and click the arrow next to Open.
Now, select the Open Exclusive option.
Finally, check that the file can be accessed or modified.

So, the above-mentioned solutions can resolve common causes of the MS Access file locked error. However, they have certain disadvantages and may not work if the MDB or ACCDB database has severe issues or the file remains locked after applying the methods. Now, let’s understand the drawbacks of using manual fixes.

Limitations of Using Manual Approaches

Requires troubleshooting: Users need to try different techniques to identify the real cause behind the Microsoft Access database locked error.
Risk of incorrect modifications: Deleting a locked file while another person is using the Access database can cause problems.
