Peugeot 207 central locking failure

Hi, I'm having a weird issue with my 2009 Peugeot 207 diesel. The central locking has completely stopped working. I can no longer lock or unlock the doors using the key fob or the button inside. I scanned it and there's an error stored in the memory, but I haven't been able to pinpoint the exact cause yet. I've checked the fuses and they seem fine. Any ideas where to start looking? It feels like my car is constantly unlocked.

Summary of the thread

A 2009 Peugeot 207 experienced a complete failure of the central locking system, preventing the use of both the key fob and internal button. Initial checks of fuses showed no issues, but an error was stored in the memory. The problem was identified as a defective plug connection to the central locking module, which was resolved by a professional repair.

Hello! I understand your frustration. Central locking issues can be a real headache, like having a leaky faucet that constantly drips. Have you checked the cable and plug connections of the central locking module? A defective connection there can definitely cause these symptoms. Do you happen to know the specific error code that's being stored? That could help narrow down the possibilities.

Thanks for the quick reply! I haven't checked the cables and plugs yet, mostly because I'm not entirely sure where to find the central locking module. Is it difficult to access? Also, I will check the error code tomorrow and post it here.

You're welcome! Accessing the module depends on the car's design, like trying to find the fuse box - sometimes it's hidden in plain sight, other times it's a puzzle. If you're not comfortable with electrical work, it might be best to take it to a workshop. A damaged cable or faulty plug could result in a full defect of the security system if not handled with due care. It could save you a lot of additional repair costs.

Thanks for the advice. Turns out the problem was indeed a defective plug connection to the central locking module, just as you suspected! Took it to the shop, and they fixed it for 95€. Appreciate the help!
