Toyota and Lexus Reflashing Services

Removing a Lexus ECUEarly Toyota and Lexus vehicles operated a bit different from the later systems do.  There are lots of differences but the main one you will actually care about is that if you lose your last key to one of these vehicles the cost for new keys seems really high.  Why is that? It’s because Toyota and Lexus (same company) in their infinite wisdom thought it would be a good idea to not give anyone access to the ECU (the part in the car that stores the chip key data) through the standard diagnostic port.  That means you can’t plug-in a diagnostic machine and simply add in keys like we can on the later models.

This leaves you with 3 options.

  1. Sell the car (Yeah right!)
  2. Tow it to a dealer and pay to have the ECU replaced, synched to the car, and then to program in the brand new keys they sell.  Make sure you are sitting down when you hear the price of that!
  3. Call us.  We can re-flash your current ECU and add in two keys for a fraction of the cost of a brand new part, labor to install and high programming fees.

Reflashing a LexusReflashing means that we write over the current files in the ECU and convert it back to its virgin unused state.  After it’s been overwritten, we can add in new keys! Here is the list of vehicles that need to be reflashed if all keys are lost.

The 1998 – 1999 Toyota Avalon, 1998 Toyota Camry and the 1998 Toyota Solara have the potential of having a Delco brand engine control unit. Delco boxes are rare and require a very special reader to reset (re-flash) the unit. If your vehicle has a Delco box we CAN reset these but the cost is higher.
