Ok I'm new here but I'm having trouble with my 04 545i. The keyless entry doesn't work and I bought it like that. I tried the pairing method but it did not work for me and I even got a new key for it but it still did not work. The dealership told me that the previous owner somehow locked the entire keyless system because he founder find the original key to start the car with or something like that. Will replacing the Keyless Module help??
