blloyd29 Posted August 20, 2007 Share Posted August 20, 2007 So I bought a 1998 Lexus ES 300 at an auction with no key's that came with it. How can I get a new key for it without replacing the ECU? THe local Lexus dealership quoted me at $1400 to replace it. REDICULOUS. Does anyone know of a place I can reflash the ECU or somehow bypass the key transponder? thanks Quote Link to comment Share on other sites More sharing options...
palex Posted August 20, 2007 Share Posted August 20, 2007 www.sparecarkeys.com The key will come to your door already cut just provide vin# and proof of ownership $ 60.00 or so not much more. My key works fine in the door and ignition. So I bought a 1998 Lexus ES 300 at an auction with no key's that came with it. How can I get a new key for it without replacing the ECU?

fastpakr Posted August 24, 2007 Share Posted August 24, 2007 The site indicates that you can save the $15 for cutting from the VIN if you can provide the key code. Do you know where this is marked? Quote Link to comment Share on other sites More sharing options...

Be careful, I believe the key they send you will need to be programmed and you MUST have a working master key for that. You probably will need to have the ECM reflashed which they will do for $125. Still a pretty good deal. Quote Link to comment Share on other sites More sharing options...
fastpakr Posted August 27, 2007 Share Posted August 27, 2007 I'm not the OP, and actually have a working master. I'd just like to save the $15 if possible. Separate question... If I just bought a key with the remote frame but not the remote components from that company, does anybody have the accurate instructions for reprogramming the keyless portion from another key (e.g. if I grabbed a used key from eBay to rob the remote portion from)?

JokeDog Posted August 28, 2007 Share Posted August 28, 2007 I'd like an answer to that "separate question" as well, but as for the original question, the $60 spare key with cut based on VIN, you'll still need a master key to reprogram it, so that won't work for you.

Firewalker Posted September 5, 2007 Share Posted September 5, 2007 I did just that, bought a lexus key fob shell and used my "guts" from another key, I do have the programming instructions somewhere, let me know and I will dig them up for you. It was quite easy to do and saved me a ton. Quote Link to comment Share on other sites More sharing options...
