CT200h Central Locking Failure

Hi, I have a 2012 Lexus CT200h hybrid. The central locking system isn't working. I can't lock or unlock the doors using the key fob or the internal switch. There's an error stored, but I don't have the code. I checked the fuses, and they're fine. I suspect a bad cable or plug, but I don't want to take apart the door panels without some guidance. Has anyone seen this before?

A 2012 Lexus CT200h experienced a central locking failure, with neither the key fob nor the internal switch functioning. Initial checks ruled out fuse issues, and a weak key fob battery was also dismissed as a cause. The problem was suspected to be a bad cable or plug connection. A workshop diagnosis confirmed a defective connection in the central locking system, which was subsequently repaired.

Did this summary help you solve your problem?

Hey, I had a similar issue with my CT200h. By similar, I mean the car locks didn't work. Have you checked the key fob battery, or whether the car alarm is causing problems? Sometimes a weak battery or a glitch in the car alarm system can mess with the central locking. Just a thought before you start pulling things apart.

Thanks for the quick reply. I checked the key fob battery, but it still happens with the internal switch. Did yours do that too? Were there any other symptoms, like issues with other electrical stuff?

Yeah, that's pretty much what happened to mine. Internal switch and key fob were both useless. No other electrical issues that I noticed, so probably not the car alarm. To be honest, I took it to a workshop, and they sorted it out. It's probably a cable or plug connection like you guessed.

Thanks for confirming what I thought. I took it to my local workshop. You were right; the diagnosis indicated a defective connection in the central locking system. It cost 95€ to repair.
