Hi all,
I have detected sometimes that, after washing my F25 2011 with a high pressure water gun, my FOB key doesn´t work. I can’t unlock my car with the FOB key. The only way to enter into the car is using the standar key to open the driver’s door. Then, when I try to star the car, it doesn´t work because the car doesn´t detect my FOB key. I hear the dong sound. Then, as you know, the only way to start the engine is putting the FOB key close to the steering wheel and push the star button again.

I have checked the FOB key batteries and were OK. However, I changed the batteries but it didn´t resolve the problem. I did it with both FOB keys.
I have noticed several times this fault, and after a week or more days the FOB key starts working again doing nothing, so my conclusion is something related to water, that it evaporates over time.

So, I have considered that the problem is not the FOB key and that the problem is with the Central Locking System (I don’t know if it is the correct name) module or antenna. I think that some water can touch the system or the antenna (if there is one) and for this reason the signal is not received by the system module.

I am surfing on the internet trying to find where those wet or damp parts are in the car in order to take a look and check if they are really wet or damp, but I have not been successful.
Anybody knows where is the module that receives the FOB key signal?

Any suggestion or help will be welcoming.
Thanks!
