So my gf smart key was stolen with her purse. She already file a police report. What can she do on her half to protect herself and the car from being stolen? She still has the other smart key. Thanks!

FUKCIN THIEVES!

One of my friend who owns a IS250, just for the kicks, was able to hack/break into his car using an API (application programming interface) he wrote in C... the API had commands to decrypt the algorithm to perform the security check with the smart key. He used some sort of RF card (if I remember) and programmed it to transmit some bits over to the IS sensor. I don't know how he exactly did it, but it was wayyy too cool.. ofcourse, he did this on his 2006 IS, I think he tried it on a 2008 model but didn't work and I'm sure he's trying to break the encryption!!!!

This guy just graduated with a BS in Computer Engg though.. and now works for Norton (the anti virus company)... weird huh?

So should she take the car to the dealer and get it reprogram?

I guess I should ask my hacker friend.. LOL.. just kidding.
I think you should speak to the dealer, just to be safe.. they should be able to reprogram the key.. but I'm not sure how all the key stuff works as I don't own a Lexus..

Good luck!

take it to the dealer and have the key that was stolen removed from her cars computer. If you can get a new key and have the add it to the car at the same time. Saves time and money from going back and forth to the dealer

Another factor to consider is the Homelink, and navigation with your home address programmed in. Before you can have the car’s code changed, have your Homelink code changed, lest this guy finds your home and gains entry. In that regard, I was told to never put your exact address in your address book. Rather, have it set for a block or two away. It will serve the same purpose, but not lead a car thief to your front door or garage.

Just have the dealer reset the code. It'll be easiest. Also have them get you a new key too to replace the stolen one.

Also, if you want. This is a more expensive option but it's just something for you to consider:

You can buy the Lexus LS keycard which is about the size of a credit card. Have Lexus program it if they will (ask them before buying it) and you now have a key to your IS that fits perfectly in your wallet

Just got a quote from the dealer, $350 for the reprogram. Is that about right?

How much is the LS keycard? It can be reprogram to work with the IS?

As stated in here already, the key that was "stolen" can removed from the cars computer.. done deal...

BUT, then you still might have the issue of the physical portion (valet part) of the key that will still be floating around, which can be used to open the drivers door.

Was the valet key still inserted in the smart key fob??
(see picture)

Good Luck

I agree with Joe your gonna need to get all 4 locks re-keyed to eliminate that problem.

350 sounds kind of steep for 2 hours of work max unless it includes re-keying the car. Sewell our forum sponsor sells them and they can be programed for an IS. The physical key wont work on an IS though.

Good luck too you

So we had the dealer do the reprogram. It came out to $440 for the reprogram and a new remote with valet key cut.

I guess next on the list is to rekey the car.

crud you need to get that valet key cut again when you have the the car re-keyed. your gonna have to get another valet key. sorry bud!

Service rep should have thought of that before hand!

WoW.. I guess you paid to have the new key cut already... I would have opted out of that one...

I think you have to re-key one drivers door, trunk & glove box...

How much does rekeyin the door, glovebox, and trunk should run? I think they told me $1g, ridiculous.

Joe there is a passenger door too?

I was wrong!

Shouldnt cost that much. Unless the keys are gold! check with a locksmith
