There are several potential reasons why a Lexus LX 570 may not start. Some of the most common causes include:

Steps to Take
If your Lexus LX 570 is not starting, it’s important to consider the following steps:
1. Check the battery: Verify the condition of the 12v battery and the key fob battery. If necessary, replace them if they are dead or not functioning properly.
2. Inspect the battery terminals: Ensure that there is no corrosion on the battery terminals that could be affecting the electrical connection.
3. Examine the alternator: If the alternator is suspected to be the issue, it may need to be tested and potentially replaced if found to be faulty.
4. Check for other potential causes: Investigate other potential causes such as a clogged fuel filter, broken starter, blown fuse, empty gas tank, immobilizer error, or faults in the electrical system.
5. Seek professional assistance: If the issue persists, it may be necessary to contact a Lexus dealer or a qualified mechanic to diagnose and repair the problem.
