i have a 2006 s430 and the door locks and trunk lid release stop working (at the same). Both the key faub and interior buttons do not get e response.

 

Find the floor lamp that is located behind the right rear passenger's heels. Push down on the top edge of the housing and pull it out, lifting the lamp out of the floor. Look behind it near the inboard end and find the yellow 20-Amp fuse. Remove it and check it carefully. If good, reinstall, if not, replace with a good 20-Amp fuse (not one from China).

Try the pneumatic equipment again...
