Situation
A Sequoia arrived with no working keys and a reluctant owner who needed the vehicle returned quickly and reliably. This year/model uses immobilizer data stored in the ECU/BCM EEPROM; with the correct approach and the right tools, we were able to recover the required data and restore full key functionality without invasive surgery or expensive replacement modules.

Tools used
VVDI Key Tool Max Pro — key programming, immobilizer management, and diagnostic features.
MINI Prog — compact EEPROM/flash read-write programmer for safe extraction of immobilizer data.

What we did (high-level)

Using the MINI Prog we read the vehicle’s EEPROM data, then used the VVDI Key Tool Max Pro to process that data and create/program new transponder keys. The operation was completed via EEPROM recovery (no module soldering or module swapping required). The new keys were tested on the vehicle and all functions — starting, immobilizer recognition, and remote locking — worked as expected.

Why this approach worked well

Non-destructive: EEPROM read/restore avoids replacing expensive control units.
Fast turnaround: The right combination of programmer + key tool significantly reduced bench time.
Reliable: Cloning from accurate EEPROM dumps produces keys that behave exactly like the originals.
Cost-effective: The owner avoided the high cost of ECU replacement and lengthy dealer procedures.

Notes for professionals

Always confirm proof of ownership and authorization before performing any all-keys-lost work.
Back up the original EEPROM dump and verify reads to avoid data corruption.
Use trusted tools and follow manufacturer/tool vendor guidance for the safest results.

This 2004 Toyota Sequoia all-keys-lost procedure highlights how modern, well-matched locksmith tools — like the Xhorse VVDI Key Tool Max Pro paired with MINI Prog — can deliver fast, safe, and reliable results when EEPROM data is available. Job completed: new keys made, vehicle returned, customer satisfied.
