Hello,
I recently picked up a spare OEM remote core and new key blank online, as well as a Mini-VCI cable. Was able to code in the new key to the Immobilizer with the software OK. Problem is, when I try the steps to add a remote (per sticky threads here, and watching videos online, repeating exactly), the car never engages to the programming mode (the locks never cycle).

Is there something I'm missing, or is there some feature I need to check in the software to see if something isn't working right or locked out or something?

Input would be much appreciated, thanks.

Are you using TIS Techstream to programs the remote key FOB? The driver side door needs to be open and unlocked. The following video should help.

I purchased Pre-Cut keys from a seller on eBay (1010Keys) which included two keys and one remote. He has raised his price from $29.99 to $35.08. I supplied the car Keycode and he was able to cut the key with no problem.

Having just acquired the TechStream software, I've been fiddling through it to learn all the bells and whistles. I didn't see a remote programming feature at first, and was only trying the key insert-remove and door open-close process. I'll give this a look later and see what I can do. I'll reply back later with the results.

Regarding key cutting, I found a local hardware store that has a drill press-router/grinder device that cuts our 'sidewinder' style keys for $20 ea. I bought my car used and was only given 1 master and the valet key, no key code. Oh well.

Thanks for input.

The keycode can be found along with an emergency key on a card. This should be part of the literature (owner manuals) that came with the car. For Lexus RX the first digit begins with a '4' The entire keycode is composed of 5 digits. If all else fail, you can still retrieve the keycode from the driverside door lock. It is engraved onto the lock. click on the link below

There isn't an open/close door, insert/remove key type of sequence to program keys for the 2007 and newer models. You have to use Techstream. Once you have Techstream and the mini VCI cable, the process is actually simpler and easier than the other methods.

I was able to figure it out in the TechStream software. Thanks for the guidance. I may go through the effort to pull the lock cylinder at some point so I can get the key code.. but that's a project for another day.

Thanks again!
