  • The first generation Toyota and Lexus vehicles may have duplicate keys programmed using a simple on-board procedure. Later vehicles need to be connected to diagnostic equipment. The transistion to the newer system depends on model and year.

    The Toyota Lexus

    With the exception of the 1997 LS 400, the first years of transponder based Toyota and Lexus cars had no provision for addiing keys when all keys are lost, or if the owner has only a valet key. The programmed key information is stored in the main computer of the car, and to add additional keys requires an existing programmed master key. If no master key is available, the factory service procedure is to replace the main computer at a cost of $2,000.00. This design proved senseless, and even got some bad press on the national level. The negative publicity regarding the key problem eventualy led them to institute a program of free computer replacement (except labor charges) if this situation occurs, but the program only applies to certain owners.

    Keys are lost to cars every day, and necessity led to development of methods to assist vehicle owners when this situation occurs. Specialized technology now allows certain locksmiths to remove the main computer, "reflash" the chip which stores key data, and program new keys to the car. We were the first locksmith in Kansas City to acquire this technology. We now have the most sophisticated equipment available for this process.

    The vechicles which need to be reflashed when no keys or only a valet key is present are:
  • '98 -02 4Runner
  • 98-04 Avalon
  • 98-03 Camry
  • '01-04 Highlander
  • '98-02 Landcruiser
  • '00-04 MR2 spyder
  • '01-02 Sequoia
  • '98-03 Sienna
  • '9-03 Solara
  • '98-04 ES 300
  • '98-00 GS 400
  • '01-04 GS 430
  • '01-04 GS 300
  • '98-00 LS 400
  • '99-02 LX 470
  • '99-03 RX 300
  • '98-00 SC 300
  • '98-00 SC 400
  • '01-04 IS 300
  • Later vehicles may have the immobilizer reset using diagnostic equipment. We are able to duplicate and originate virtually all Toyota and Lexus chip keys.

    A BIG problem with the three-button remote head transmitter Lexus keys is breakage. These keys are typically about $250.00 from the dealer. Thankfully replacement key shells are now available which can be cut from your key, and use your existing transmitter assembly.
