Dear All, I recently bought a 320D (2010, base model) used car and have only one Key FOB as the previous owner says that he does not have the second Key-FOB. I inquired from at the dealership about the cost of the new Key FOB and they mentioned that it will cost me around $400(INR 24,000). On e-bay the used FOB is for $60. Please advice if the used FOB can be re-programmed to be used with my car.
If yes, please suggest the way to do it. Alternatively, please advice where I can buy the cheaper new Key FOB and how to program it so that I can use it with my car. Thanks, Shekhar.
Bottom line is you can't get a key fob coded to work with your car unless you buy it new at the dealership. That is incorrect.
Many locksmith's are able to program new fobs for BMW's. The issue is that the transponders that are used in the fob's are writable only once. Once they have been used, the transponder chips can not be written to again. The transponder chips are available for only a few dollars on ebay. So, if you would like, you can take an old, used, key, and replace the transponder chip.
There is also a company that claims to flash BMW keys back to original factory condition, but I think they probably just replace the transponder chips. But, even if you get a key with a fresh transponder, and it should be programmable, it's unlikely that a dealership will program it for you.
But it IS possible to program the chip yourself, it just takes more effort than most are willing to put out. I think it's outrageous for dealerships to charge such an huge amount for basically nothing. So, I purchased an AK300 kit. You need to remove the CAS board, and solder a few wires.
Then you can program keys for your car - as long as they have a factory set transponder chip. This is basically the same process that thief's were using directly thru the OBDII port. Wisely, that is no longer possible, you need physical access to the CAS board, which is something that a car thief is not going to have.

That's the issue - the hardware, which is why you can't get an existing key (i.e. My friends dead e90's CA key) to work with my e60. As I read what you said you basically said I'm not wrong? My understanding is that every CAS is preprogrammed from the factory with 10 key IDs. Example (simplified for illustrative purposes) Car A: 1, 3, 5, 7, 9, 12, 14, 16, 18, 20 Car B: 2, 4, 6, 8, 10, 11, 13, 15, 17, 19 Ordinarily if you lost key 2, with code 3, and went to the dealer, they would contact BMW NA who would see that the next key in the series (for your VIN) is code 5, so they burn a key with your car's electronic ID and code 5, and send it to the dealer. Then you pair it to your car, and the CAS then recognizes that new key as authorized in its list and activates it. Someone has said that after you get to key 10 in the series, the next one you need will force you to get a new CAS to start a new series of keys.
Suppose you own Car A and you buy a key from previous owner of Car B. His key you CANNOT recode.but someone mentioned already you can change the chip, but you cannot reburn the code already burned onto the chip.
Part of the challenge is knowing what the next code in the series is. Don't know how lockmiths with equipment to 'burn codes' know the next number in the series. That is incorrect.

How does it work? Where did you get the kit?
How does it work? Do you understand that, as described, installation of the 'kit' in question entails removing the Car Access System (CAS) control module from your car, partially disassembling it and taking a soldering iron to a $400 part? If you screw it up, your car will be stone dead, leaving you with no alternative but to have it flat-bedded to a dealership to have a new CAS module installed and coded to the car.
Oh, and then you'd still need to pay for new keys and programming thereof. Assuming the above has not put you off, don't forget that besides the programmer itself you still need to source virgin key fobs and/or transponder chips. In the end you'll likely be out more than the cost of two keys at the dealer.
Finally, no one is likely to do all of the above work for you, let alone at a bargain price, because this is precisely how a professional thief would circumvent the system on a stolen BMW.
To reprogram the round BMW key, enter the car and close the door before inserting the key into the ignition. Look at the ignition and turn the key to position one, and then turn it back to position zero. Remove the key and press and hold the button that unlock the car.
Keep the finger on the button while pressing the BMW emblem button to lock the door a minimum of three times in 10 seconds. Remove the finger and look at the light on the key; make sure it flashes for about 10 seconds, and listen for the doors to lock and unlock, which shows the programming is complete.
To reprogram the diamond shape BMW key, unlock all of the doors, insert the key and turn it to position one before turning it off. Do this within five seconds of getting into the car, or the system may not recognize the reprogramming. Remove the key, press the unlock button and keep a finger on it while pressing the BMW button three times. Remove the finger from the BMW button and listen for the car to lock and unlock, which means the reprogramming was successful.
