I'll paypal you $20 to ship it to me depending on the FCCID. I only have 1.

 

OP: You could program the key to work with your vehicle using Techstream

 

 

depends on the FCCID.

 

 

where did you find it? If you found it in a grocery store parking lot for instance, I would give it to the grocery store customer service desk, in the event the owner returns to claim it. Though after 4 days, they may have already done that, not likely to do it again.

 

 

You can drive off without it, car will make beeping sounds or they didn't drive their lexus that day. Was the fob on its own? Realize its a moot point now but my nephew managed to lose my fob while driving my car a few years ago....i asked him why he didn't notice the beeping..

 

is it possible to reprogram a non-virgin key?

 

i wonder if this could also happen by storing the fob near a wireless router? i seem to be replacing my fob battery about every 6 months, and i store my key when i get home, in a drawer by my wireless home router......

 

Router nad fob use way different frequency. If your fob is within the range of your car battery
won't last long. To test. try to unlock the car with fob, if it does your fob is within range. Do you
have smart key?

 

You could try a faraday bag

I consider this an important message to all GX owners (along with any other vehicles with similar keys)
Okay, it finally happened. first time I've ever lost my keys (key fob included).
My wife and I were celebrating our 34 year anniversary along with her birthday at Disneyland all day, had a great day, getting late and ready to go home.
Walk through the massive parking structure to my rig, pull on the door handle... Nothing happens. Pull again, still nothing. WHAT??? (BTY, it was not somebody else's GX I was trying to open, which I know has happened to others, trying to open the wrong vehicle, my rig is very unique)
I check my key ring on my belt loop and sure enough my Lexus GX 460 (I think 460 represents the price of a new key fob) key fob was missing!!! I had my house key on my key ring (small carabiner) but no fob. Called Disneyland security and lost & found... Nothing.
Had to call my daughter and have her drive 40 miles (each way) to get me my extra key fob.

So... Lessons learned:

• REALLY glad I had the presence of mind to get a second key fob when I purchased my vehicle (it only came with one)
• REALLY need to have some method of having a second physical key hidden external on the vehicle and a key fob in a Faraday/RFID blocking pouch in the vehicle for after I unlock the door.
• Or keep a key fob in a Faraday/RFID blocking pouch hidden externally on the vehicle.

I called the Lexus 24 hour help(less) line and they just told me I'd have to tow the vehicle to the nearest Lexus dealer and have a new key made the next day.

It made me think of what this would cost if it happened while traveling out of town! An extra night's lodging, and who knows which Lexus dealer and how far we'd be if I were to lose a key fob in the middle of nowhere? Then losing a day of vacation/travel and that's assuming it was lost on a weekday! If it was a weekend, then one is looking a several nights lodging. Towing costs, lodging costs, extra meals, it would turn into a real life Griswold Vacation!!

 

does the Smart Card work with your model?

if it does, get one put in wallet, done deal:

 

I usually bring 2 keys with me whenever I'm away from home on long trips with my minivan. I keep one in my wife's purse.
You can also get one of the minimag hide a key box, remove the battery from the remote and put it in there and hide it under the car when doing trips.
