Do it yourself - 49 immobilizer reset files. These files are virgin dumps for different Toyota vehicles, covering years from 1996 through 2005.
These files are to be written in the immobilizer EEPROM chip, located in the vehicle's Engine Computer. This will reset the Immobilizer, so the vehicle accepts your current old or new keys. Some of the files are for the external Immobilizer module or immobox and some are for the ECM. You will know by the part number; a part number starting with "89661", is for the ECM, while if it starts with "89780", then it is for the immobox.
For correctly using these files, you will need an EEPROM programmer and an SOIC-8 SMD clip for either programming it in circuit or off-circuit.
The EEPROM programmer can be any inexpensive type, able to accept serial EEPROMs like the
93C46,
93c56,
93c66,
25020,
25040,
25080 and
95040. The clip is made by the "3M" Company and the "Pomona" Company and it costs about $15. As mentioned, it is known as an SOIC-8 SMD clip and can be acquired at online electronic catalogs, like Digikey.com. Below are pictures of both tools.
The procedure is taking out the ECM computer or Immobox from your vehicle, open it, locate the small 8-legged immobilizer chip and reprogram it with the corresponding code. After that, you are ready to reinstall the ECM in your vehicle and drive it with your existing or new keys. No soldering/desoldering needed in most cases. That is the purpose of using the SOIC-8 clip.
These codes can be used as many times as you wish, as the EEPROMs can be completely reprogrammed several 1000's of times and you can do this on as many vehicles as you wish, making it ideal for selling the service of clearing or resetting the supported Toyota cars. In the picture below, it is shown how the SOIC-8 SMD clip is positioned over the EEPROM chip:
The package includes the dumps and general instructions. EEPROM Programmer and SOIC-8 clip are not included. Please note that this package is intended for technical experienced personnel only.
SOIC-8 Clips, "Pomona" brand, can be obtained from Digikey.com in the link below. While the clip pictured in that link is for an SOIC-28, it is for representation only, as the part number in that page is for the SOIC-8.

Because a wiring harness is needed to use the clip, you may construct your own. It is not difficult, but you may also obtain complete assembled kits from several sources, like the one shown below.

Lastly, you will need a serial EEPROM programmer to read/write the EEPROM chips. While there are both expensive and non-expensive units available, what is really important is that such unit is able to work with the target device or devices (EEPROMs). Below are two examples of good programmers.
