Terry’s Locksmiths: Expertise in Lexus Ignitions, Keys, and Door Locks

Terry’s Locksmiths is well-versed in providing locksmith services for a variety of Lexus models, covering ignition repairs, key programming, and door lock solutions. With Lexus vehicles featuring complex security systems, including transponder and proximity keys, our experienced team employs cutting-edge tools and techniques to resolve any issues efficiently. Here, we share insights into our expertise, highlighting recent job cases and technical details that showcase our capabilities with Lexus vehicles.

Lexus Key Programming and Chip Cloning

Lexus vehicles, especially older models like the 2004 ES300, often require manual procedures for programming remote keys. Our technicians can handle various key types, including turn key remotes, transponder keys, and proximity (PROX) keys. Using advanced tools like VVDI Key Tool Max, Autel, Tango, and Orange, we can program keys, clone transponder chips, and add new keys without EEPROM in many cases.

For example, on a 2004 Lexus ES300, we programmed a spare 3-button flip key (MK5814) using the VVDI Key Tool Max. We applied a manual procedure to program the remote, which was straightforward due to the vehicle’s age and key configuration.

Case Studies: Lexus Key and Ignition Services

1. Job 79722: 2004 Lexus ES300 – Spare Key Programming

   • For a 2004 Lexus ES300, we provided a spare key with remote functionality. The aftermarket 3-button flip key was programmed using a manual procedure to integrate the remote functions. This key cloning approach avoided EEPROM programming, making the process more efficient and accessible for the customer.

2. Job 59235: 2000 Lexus IS200 – All Keys Lost

   • When all keys were lost for a 2000 Lexus IS200, we used a Tango tool to program a TOY40 transponder key. The process involved removing the door lock and decoding it to cut the key. The vehicle’s ECU was located in the engine bay, and we read data from the 93C56 EEPROM to facilitate key programming.

3. Job 57766: 2009 Lexus IS250 – Spare Proximity Key Setup

   • In this case, the customer required a spare proximity key for a 2009 Lexus IS250. We programmed an MK8646 proximity key using the VVDI Key Tool Max. The key, which operates at 314 MHz with a 4D chip, was added without needing to remove any components from the vehicle.

4. Job 75862: 2007 Lexus IS250 – All Keys Lost

   • For a 2007 Lexus IS250, all keys had been lost, necessitating a more complex solution. We used Autel and VVDI Key Tool Max to program a 3-button PROX key (MK6397). The process involved removing the immobilizer box from the rear panel of the boot compartment, reading the EEPROM data, and transferring it to a Tango emulator. Once the data was written, we added the new key using a programming tool.

5. Job 81922: 2003 Lexus IS300 – All Keys Lost

   • In this scenario, the immobilizer chip had to be removed from the board to add a new key. Using Tango and Orange tools, we programmed a Toyota TOY48 non-remote transponder key. The process required precise soldering techniques due to the hard EEPROM configuration.

Working with Lexus Door Locks

Lexus vehicles often feature TOY40 and TOY48 keyways, which require specific tools and procedures for decoding and cutting. For older models (1999-2005), door locks can be disassembled to read the lock wafer positions directly, facilitating accurate key cutting. On newer models, we decode the lock by removing the driver’s door lock and using specialized cutting machines.

For example, on a 2010 Lexus model, programming a PROX key involved removing the immobilizer box from the boot and pulling out the door lock to cut the key. The vehicle’s 93C86 chip code was used to program the PROX key directly.

Handling Proximity Key Issues

Newer Lexus models, such as the 2013 RX450H, often utilize genuine proximity keys that can present compatibility challenges. For these vehicles, tools like Smart Pro, Autel, and Zedfull are used to add keys or troubleshoot issues with previously used or unlocked keys. In one instance, a genuine key for a 2013 RX450H did not function even after programming, requiring further investigation to resolve compatibility issues.
