How to Use Your BMW Key Fob Remote
Although pre-programmed for your car, your key still needs to be activated in order to be used.
Hold your new key fob flat on the dim battery indicator next to the steering column to accomplish this. After then, keep pressing the start/stop button until the “no key” warning light goes out. To check that activation was successful, press the start/stop button once more.
If this doesn’t work, you might need to activate your new key while removing your old key fob from the signal range to avoid interference. To accomplish this, first unlock your BMW with the existing key before having someone carry the key a short distance away from your car. After that, you can push the start/stop button while holding your new key against the steering column.
new key fob or reprogramming?
I see, so even though the other key to a different BMW’s rfid chip won’t start the engine, the remote will still work to lock and unlock the vehicle. I suppose I could use the valet key to start and the remote key to unlock, but I believe the problem with that is that the battery won’t last if it’s not in the ignition constantly. I wish I could have removed the rfid from the valet and installed it in the new remote.
I’m sorry to bring up a stale topic. I’m not certain that I comprehend (or at least I hope I don’t). I own a 2003 325xi. The transmitter’s battery was bad, and one of the buttons was broken. It now functions since I resoldered the chip and put a fresh battery. But when I took it apart, I wasn’t as careful, thus the plastic is poor. To replace it, I purchased an uncut “new” fob. Do I understand what I read above correctly that it won’t work since the brand-new, uncut blade lacks an RFID chip before I spend the money to have it cut?
Does this not work? I considered getting a used key from someone, changing the blade, and having it reprogrammed. Also undesirable Any advice would be greatly valued. I appreciate it.
You can switch the rfid chip presuming you can spit open the valet key like you can the basic key. The issue is that if you do, the ignition will stop working.
Summary
Your key fob can be reprogrammed to work with another vehicle. You can usually complete it on your own in just 10 minutes, although it does require a few steps and close attention to detail.
There are, however, several exclusions to this. The key fob cannot be programmed to work with a vehicle that was not designed to accept it or that uses a different type of electronic car key. To be sure, refer to your car’s owner’s manual. Taking it to a professional should remedy the problem if you are unsuccessful, but you will have to pay for the labor. That is preferable than purchasing a brand-new key fob, though.
