Practical Scenarios:

I have an Access database that was previously locked. Now I have to make changes to it but cannot figure out how to unlock it. The icon has a little lock on the upper right hand corner, and the menu control options are gone on the menu when I open it. How do I regain access into it?


I have an Access database that is on a network drive that multiple users can access. The database corrupted this morning and I am in the process of trying to fix it. The problem I am having is when I attempt to rename the database it says it is currently in use by someone. There is no .ldb file associated with this file so at this point and am dead in the water because I can’t rename it, compact it or anything.

Does anyone have any suggestions?

Password defending an Access database permits you to defend sensitive data from prying eyes. At times, you might encrypt Access by means of a password and then misplace or overlook a password and consequently don’t have access to the MS Access database file. But do not panic, because now you can securely and efficiently recover Access mdb, accdb file password that’s forgotten or lost on Windows 8/7/Vista/XP by way of four influential assault types: Brute-force with Mask Attack, Brute-Force Attack, Smart Attack, and Dictionary Attack. The program chains every version of MS Access counting Access 95/97/2000/XP/2003/2007/2010.

Accdb Vs. Laccdb

All the versions of MS Access bring into the usage of locking files that passes up the users from operating a similar record at a similar point of time. MS Access 2013 databases encompass a file extension of ACCDB whenever you crack Access Database password.

Since the 2007 MS Office version, ACCDB is the default Access file extension. After locking any file, it shares a similar name and location as the primary database file, but their extension becomes LACCDB. Earlier than the 2007 version, such extensions were MDB and LDB. The LACCDB file continues to be open until the final user ends the database.

In uncommon situations, this locked accdb file avoids eliminating itself and should be eradicated using manual methods. If you are well aware of the assigned name of the database, but you are not sure that where the database is amassed within the system, then you are facilitated with a couple of alternatives: either try executing all files searching technique along with the LACCDB extension or else you can try to contact your network manager and provide them every required detail.

Where And How Access Database Stores The Password?

unlock access database

It’s pretty obvious that you have lost or forgotten your MS Access password and looking for some perfect solution to Access password recovery. Before trying to recover Access Database password, it’s important to learn how Access stores its password.

Technically, MS Access database password stores in the following regular pattern.

1). Jet 3 –

In this mode, the MS Access database password gets saved in the header of the MDB file and the format remains as plain text.

2) Jet 4 –

In this, the password is encrypted with a basic XOR pattern algorithm depending on data and times of film production. Further, it saves data in the MDB file header.

3) Jet 3 & 4 –

The password is further encrypted with an XOR pattern affecting the MDB file.

4) ACCBD Files –

The password is not encrypted as plain text in the header file at all.  Instead, the new # value is allocated to authenticate the user’s password validation. Hash produced by the tool is a combination of two RC4 and SHA-1 algorithms.

In order to encrypt your Access database if you have chosen the pattern then it’s quite difficult to crack. This especially applies with the ACCDB files but MDB files are still possible to be recovered.

Manual Ways To Unlock MS Access .mdb & .accdb File:

Here are the following fixes on how to unlock Access database password:

Method 1# Using Decompile Option

You can try copying the database into a different location. The feature won’t be locked for any reason. Then you can try working the way you want to until you resolve the lock issue that’s occurring with the original file.

And if you are facing this error because of the VB code corruption of the file, try opening the database with the help of the “/decompile” option. To do this follow the steps mentioned beneath:

Start Run:

“C:\Program Files\Microsoft Office\Office\msaccess.exe” “C:\example.mdb” /decompile

If there is no .ldb file related to the MDB, it will be complicated to find out the exact user that’s locking your database. If you have a very limited number of users, you should start again their systems. It would be a primitive technique but is quickest to try rather than accdb password recovery through additional procedures.
