key programming without master key


Recommended Posts

Hy everyone. hello.gif

First of all, I apologize about my English . . . I'm french ! biggrin.gif

I post here because after I had read lot on the subject, I can't have an answer about my questions.

I'm a RX400h 2007 french owner and I bought it three years ago with only one black key with 3 remote  buttons, fully functionnal !
My seller (multi mark seller not Lexus one) wasn't honest by mail and phone and after I spent 3 hours by train and one hour by taxi, he give me only one key and told me "Do you want it or no" . . . and I bought it ! argue.gif

In 2015, I tried to get another key with my Lexus Local Seller, but he told me he couldn't because my key is actualy known by "calculator" as a wallet one (not a master one) and so he couldn't programm a new one !
I tried to get one key with a local key store, and I've now a key without buttons and I can start engine with it but I can't switch off alarm with it so it is not very usefull.
I bought a new blank key with remote on internet that was cut by a key store but wasn't programmed because no one here can do it!

I'm now a bit lost . . .

I want to know what can I do in that conext to have a new fully functionnal key with remote !

Thanks a lot to the community and thanks before your answer. inlove.gif

Regards

Go to "real" auto Locksmith ( LS). They are be able to program a  valid lexus  made Key. I own such a business and we do it all the time!

 If there are too many keys already programmed  a real auto LS can wipe the computer clean  ( just Like Clinton) and re program the  keys you have.

Hello, bayray:

Thanks for this info.  How much does it cost to program a Lexus key?  We have a key for other Lexus car (same model), but we sold other one.  So, we can use this one for our current Lexus car, if it can be programmed.....Thanks again!

If its the same year and model its likely you can obtain a new shell and have a LS cut it to match the cuts  on the car you retained.

Programming cost depends the area you are in plus the distance the mobile LS must travel to. Figure >$125 - $200 or the new shell , cut and programmed.

if its push start it may not work since those need to be unlock to  program them.. Good Luck

I purchased a 2005 RX330 from a dealer in Rhode Island. The master key was lost, there was only one  Master key and a spare key that can lock/unlock  car manually and of course start vehicle.  The Lexus dealer will NOT provide me the P/N for the remote for this car,stating than I could go then after market and attempt to get a new Master key that will operate the entire vehicle. It did not take a rocket scientist to know the dealer was right. However,  I have a very limited base key only. I would appreciate any counsel how I might get a new master key made.
