To improve key FOB security, place the FOB into "Battery Saving Mode" (BSM) ** after ** exiting and locking the Land Cruiser.
BSM completely disables the key FOB--improving security and increasing life of the CR2450 battery.
To enter BSM, Press and Hold the LOCK button. While holding down the LOCK button, press the UNLOCK button twice.
The red LED on the FOB will flash 4 times, verifying the FOB is in BSM.
For all the details of this subject, please refer to the LC 2024 Owner's Manual, pp. 152-156.
Important Note: BSM prevents the FOB be being used.
To Cancel BSM, press any of the key FOB buttons...
Depending on the type of additional security you're looking for, an option to review might be disklok.
Recommend getting the Cover for the LC steering wheel to prevent disklok from possibly making marks on the steering wheel.

According my discussion with disklok USA, the size needed for the steering wheel includes the thickness of their Steering Wheel Cover.
Disklok also told me that if a steering wheel diameter borders between the maximum (Small) and minimum sizes (Medium), it's always best to select smaller size disklok (next size down)...rather than going with a larger size.
For example:
Small size: 13.7 - 15.3 inches
Medium size: 15.4 - 16.3 inches
For the LC steering wheel--which is difficult to get the exact diameter because the center of steering wheel protrudes--it's about 15 inches or so. Given Disklok's technical support advice, Small is what I selected.
I recently received all of the above items, and Small is the proper size for the 2024 LC steering wheel.
Absolutely phenomenal design.
One just needs to take time and be careful installing it over the covered steering wheel...because it's quite heavy.
You don't want to bang it into anything on the steering column, dash, or anything else...
