Default HELP - somebody must know

I have a 1997 Lexus ES300 - I have lost my last key - I do have what Lexus refers to as a 'flat' key. This key fits in the ignition, but will not start without the electronic card that came with the car. I bought the car used and do not remember seeing such a device - I only have the flat key.

Without taking it to a Lexus dealership, does anybody have any suggestions on how I can start this car - can it be hot wired? Does anybody have any tricks up their sleeve? Help....

The only way to get this car started is to have it towed to a dealer and have them program a key. The whole logic behind chipped keys is to render hotwiring the car useless, as without the chip reporting it's unique identifier to the ECU the engine will not start. Often times they won't even crank.

i hope it doesn't have tge emobilizer system Lexus used around that time. if it does you need one of the black keys to program a new key. with out it you have to replace the entire security system to get a new key programed. back when I worked there in 1998 it was about a $2500 job. Good luck call your dealer.

Try calling giving your Lexus the VIN. They were able to make a replacement key for me with just the VIN.

Can't be hotwired. You've got to get another key somehow.
