i just had my tires replaced and i did not have my wheel lock key since it was removed when i installed the false floor for the stereo.

the tire shop (not lexus) was able to remove the lock but now i only have 4 lug nuts on each wheel

i want to get a replacement lug nut (not wheel lock) does anyone know the exact size i need to get?

 

The tire place didn't offer to sell you some for a few bucks each?

 

Have to get the flat faced lug. 12X1.5 I believe. Same as Honda pitch. Anyway, just get an OEM Lexus lugs off ebay. Got a set for my previous LS and they worked perfectly.

 

12x1.5 , also remember the stock wheel lug nuts has washers

 

kinda curious how you had your system installed. i have one installed under the floor panels in my rx330, i asked the installers to make the amp quick to move so if i had to access the spare tire, it would be easy to do.

 

Everyone is correct 12X1.5 thread pitch. You can goto your local toyota dealer as well. Most of them have that big washer on it.
