Keyfob not allowing me to unlock doors by pulling handle. Can't start the ignition unless I stick the key in the slot either..... Any thoughts? I think I need to get it re-programmed at the dealership but thought I would bounce this off all of you.... I just took delivery and this is how I got it....
Thanks.....

Make sure SmartAccess is turned on under the dash, above the driver's right foot / knee. Two buttons: SmartAccess disable (on/off) and TPMS reset (momentary contact) & one **** for exterior beep volume control.

Are you using the valet key? When I bought my car, they gave me the valet key and I couldn't unlock doors by touching, can't open trunk with the button, and couldn't start it unless I put the key inside the slot.

After they got me a new key and programmed it, everything is working correctly.

I think the way to tell if it's a valet key or not is if the key fob doesn't have a trunk release button, it's a valet key. The key with a trunk release is the regular key.

Hope this helps!

It could be a bad fob battery. Mine doesn't register from time to time which I suspect is a dying battery.

ok...Caddy nailed the first part... Once I pressed the smart access button I was golden. Now I need to figure out why I cannot turn the ignition without having the fob in the slot.... ideas?

Change the battery in the fob. Less than 5 bucks and you can do it yourself.

Thanks CG, Jay et al but the battery didn't fix it.... no worries... I have a few warranty items so I will tack this on to the list.

I believe that the battery is only used to power the "wireless remote control" transmitter (Lexus' name for the door & trunk lock/unlock buttons).
The SmartAccess ignition uses a passive chip (like RFID) and does not require power.
It should work even without a battery installed in the key.
My guess is that the key needs to be "programmed" - actually the car needs to be programmed to recognize it.

Is this a master key and up until just recently, it was all working just fine? Anything new or changed recently we should know about?

Hey Kg I took the fob to my local Radio Shack and they installed the new battery for free.Just pay for the battery.Sometimes you have to turn the steering wheel so the ignition will turn without inserting the fob

yep thanks.... not the issue... I think it needs to be re-programmed. I have tried turning the wheel a few times... heck... just for grins I will try again....
