![]() ![]() You can have your one good key "cloned" if you can find someone with that tooling, but that isn't the same as a new unique ID key, so memory functions etc won't work as designed.Ĥ: You cannot just go buy a random key, virgin key, your old key, etc, plug it in, and "mate" it to your car or reprogram it. No locksmith (at least in Texas) has the ability to properly generate replacement BMW keys. I have yet to find any reputable source in the USA with this bmw CAS specific tooling and the know how. Then another tool can program a key transponder to match. There exists some very expensive "hacker level" tooling and software that can reach into the CAS via the OBD port and decipher its saved transponder numbers. This is why you provide your VIN number and proof of ownership to BMW, so they can pull up your VIN's assembly records and send the correct uniquely programmed key. The only keys that will work with that car will be programmed with those matching ID's. Typical automotive locksmiths don't do CASIII or above BMW keys.Ģ: You can only buy a key from a franchise dealership, where it comes from the factory in Germany pre-programmed with the correct transponder ID for your VIN.ģ: The CAS module leaves the factory programmed with 10 unique transponder ID's already flashed into the module (these records are kept at BMW factory). Full list retail on a new comfort access key is $281 ($230 street price), the non CA key is even less. There is a lot of misinformation around this subject.ġ: A replacement key fob is not $500. ![]()
