Hey Guys,

I spend most of my time in the SC 400 forum but my wife drives an 05 LS430. It has the combo key and fob in one. The car has the option if you have the key on you can open the locked door, open the trunk and crank the car with using the key. Under the dash are 2 bottoms labeled key and tire. I accidentally pushed the key button while resetting my low tire inflation warning. Now my key no longer allows me to do the above options. How can I reset / program the key. The key does work to lock and unlock the doors by using the buttons on the key.
Any help would be appreciated.

 

Sounds like you disabled the smart key when resetting the tire pressure warning. It's an on / off button right there. Probably just need to turn it back on.
