I need an ignition key for my ES300 1997 lexus. Does any one where I may get one without replacing computer

 

I'll assume you have a chipped key. Do you have at least 1 original key left? If so, the dealer can program it.

 

You can have a new master key cut from the dealer based on the VIN. Just bring proof of owner ship. The basic blank non "L" key is about 25, the non remote "L" key is 50. If you want the fancy pants remote key its about 250 if I remember correctly.
