Dell BIOS PASSWORD

Using a Backdoor BIOS Password

Some BIOS manufacturers implement a backdoor password. The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time. 

Christophe Grenier has written a program that will calculate the master BIOS password for Dell Latitudes from the Service Tag number. That program is available at http://www.users.globalnet.co.uk/~skynet/zips/latitude.exe.

If you cannot boot your Latitude to run this program, you can get the master password for your Dell by calling Dell Technical Support at (800)624-9896.

Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Latitude.

If you were not the original owner of the Latitude, Dell will transfer registration of the used Latitude from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

To transfer the registration of a used Dell Latitude, fill out the Transfer of Ownership form on Dell's web site.
