Instructions on how to actually unlock your ThinkPad (TP) are in the User's Guides

EEPROM Location and Type

T430 EEPROM you treat it as a 24RF08

Locating the T430 connection points

Switch the T430 OFF.

You should have already downloaded the hardware Maintenance Manual for your ThinkPad model, if you have not done so use the link below to download it now,

Download the Hardware Maintenance Manual (HMM) for your TP model

The links above are to the Lenovo site, if it doesn't work, don't panic, it isn't broken, their site is shut down daily for maintenance and at those times they display spurious messages like the page you requested cannot be found, wait a good while and try again.

There is a "shortcut" for the T430, remove the RAM cover, move the yellow CMOS backup battery aside, carefully cut and lift the black plastic to reveal the SCL and SDA connection points

SDA and SCL connection points

 

You do not have to access the actual EEPROM, the shortcut above is much easier. Location of the EEPROM is depicted below, to access it you have to completely dismantle the T430

Once you have your HMM search the manual for "Removing and replacing a FRU" then scroll down to System Board, follow the instructions in the manual to remove the System Board to gain access to the connection points.

SDA and SCL connection points are shown in the photo below

I receive many emails asking about the GND connection, in reality it is very simple, you use some kind of a clip so that you don't have to hold it in place, you DON'T HAVE 3 HANDS and there are 3 connections, GND SDA and SCL, so have a clip for GND, then you can use the 2 hands YOU DO HAVE to hold your SDA and SCL probes in place.

Almost any large piece of metal or the screws for the external connectors of any ThinkPad are a good GND connecting point.

Anyway a picture is worth a thousand words

Keep things from electrically shorting out, later you will need to plug in the AC adaptor and switch ON the TP, then you will need to hold 2 probes in place to the SCL and SDA points on the system board.

See my page on Options for Clips and Probes including making your own probes.

This page ONLY describes how to connect the KeyMaker Interface to the EEPROM.

The instructions on how to Recover or clear a Supervisor password are in The "User's Guides" click here

Assembling your TP - AFTER - you have finished.

Follow the Hardware Maintenance Manual [FRU System Board], very carefully, double check screw type and size for each individual module.  Assemble the TP in the reverse order used to dismantle it.
