I would switch to a 'Synthetic Blend' first - and stay with that for the next 3 or 4 oil changes (watching for any oil leaks to appear), before going to a full synthetic oil.

its behind the cover on the side of trunk

there should be a switch in the car to push to unlock the trunk ,i think its in the glove compartment

Welcome to Fixya

Check to see that the safety cover in the trunk is properly aligned in the brackets. It must depress a switch on either side of the trunk for the roof to close.

sorry but cannot help here as this is a complete panel behind the console,now what you could do is rewire the just the hood (sorry top in american) its easy to do and you just need a switch from a window mechanism ,drawing a diagram now so if you find the feed wires from the motor in the boot and run a feed and a earth then away you go

U are going to need to make a trip to the Lexus dealer to reactivate the system, they will need to plug a special electronic system scanner in and reset the system, in the future buy a battery backup while the main battery is disconnected, it plugs into the cigar lighter and keeps the settings intact.

go to your local library and look in a "Chilton's Auto Manual" it will tell you how to do this; R&R project
