Does anyone know if it possible to add the comfort keyless access to a 2008 BMW X5 4.8? I can get the touch unlock door handle and I have seen where there are selling keyless modules with keys and antennas. I am just not sure what all is needed and if it is possible to add the touch open door handle and the option to start car without inserting the key. I purchased my car with 52k miles a few months after having a 2002 X5 for 10 years. The only thing that I do not like is that it does not have the comfort access locks. I would rather spend some money to add them if possible than buy another X5.
