Transponder Key Programming

My family just bought a 1992 Lexus LS 400 and we have one master key. We ordered another key on eBay to avoid the outrageous prices everywhere else, but I don't know how to program it and I don't have the original code. Can anyone who knows how to do this help?? Thanks!


I also have a similar problem with a Honda Civic. If you can help with this one too, please do so. Thanks!

1992 LS400 does not have a transponder system. It is high security key or what is known as laser cut and what it has is a button on the side of the key to open and close the doors. If that's what you mean, you can't do to much. You need to replace the module and when you buy it new, it comes with 2 keys that you would need to have a locksmith duplicate for you.

What year is the honda?

Hope it helps
