1- Can anyone tell me where the tire pressure sensor "battery" is located. Mine has been on for awhile and everything I have read says when all else fails, change the battery.

2- It appears I have a blown speaker in the right door panel. Anyone know how to get at it ??

1. Each sensor, one per tire, has a lithium battery inside it which is NOT replaceable. Typical life is 8 to 10 years. Each sensor is color coded.
2 Yes. There are several well illustrated threads. This is one of the best threads. But the photos are gone now. You can ask the moderator to restore the photos in the step-by step instructions. https://www.clublexus.com/forums/lex...all-sc430.html

BTW there are several repair kits or services to fix the speakers which as notorious for failing.

The TPS are mounted inside the tires on the rims (wheels) integrated into the valve stem. The tires have to be removed or at least broken loose from the rims to gain access to them. If you have a warranty, it should cover them.
