Lexus LC Central Locking Failure
Summary of the thread
A 2020 Lexus LC hybrid experienced a central locking failure, with the system unresponsive to the remote, door handle buttons, or interior switch. Diagnostics indicated an error in the central locking circuit, and initial checks of the fuses did not resolve the issue. After consulting a technician, the problem was identified as a defective cable connection, which was subsequently repaired.

Thanks! I checked the key fob battery; it's fine. The car alarm isn't acting up. Where is the security system module located in the Lexus LC?

Okay, so the key fob battery isn't the problem. Honestly, I'm not sure where the security module is in your LC - they hide those things pretty well! But with that error code, it sounds like a defective cable or plug connection, like your mechanic suggested. I think you should take it to a workshop before you cause more damage trying to find it yourself.

I consulted a technician. They confirmed a defective cable connection and fixed it for 95€.

That's frustrating! Have you tried checking the key fob battery? Sometimes a weak battery can cause the remote locking system to fail. Also, is your car alarm going off randomly, or behaving strangely? A faulty security system module could interfere with the central locking.
