How to Program a BMW Key Fob

BMW Key Fob

Whether you’ve just replaced your main key or you’re syncing additional keys with your vehicle, there are a few things you’ll need to know. Luckily, learning how to program a BMW key is easy, and the process itself is even simpler. This short guide will teach you what to do in each scenario, and if being your own BMW key programmer isn’t as rewarding as you expected, you can always schedule an appointment at our Bloomington BMW service center.

BMW Key Fob Replacement

So, you’ve lost your BMW key fob and you’re in need of a replacement. Here’s what you need to do:

  1. Visit a local BMW dealership, like BMW of Bloomington
  2. The technician will ask for your vehicle’s 17-digit VIN number, which can be found near the front of your windshield or in your driver’s door jamb. Of course, you’ll also need to prove that the vehicle is your own by showing your driver’s license, car title, and registration.
  3. You’ll need to pay a fee in order to have BMW send you the new key. Contact us to get the current rates for BMW key fob replacement.
  4. The new fob will be delivered to whichever dealership you initially contacted. We can mail it to you, or wait for you to come pick it up!

BMW Key Fob Battery Replacement

If your key fob is fine, but you need to replace your BMW key fob battery, you’ll need a CR2032 battery. These small batteries are sometimes referred to as “watch batteries,” and you’ll want to make sure you’re using the right size.Just remove the key fob cover, carefully remove the old BMW key fob battery, and place the new one in gently. You’ll be back on the road in no time.

Programming a New BMW Key from Scratch

BMW key fob battery replacement is usually quick and painless, and so is programming a new BMW key. To start, you’ll still need to program the key fob once it arrives at your home near Decatur or Pekin. If you still have a working BMW key fob, your process will be different (jump down to our next section). If you don’t currently have a working BMW key fob, you should take the following steps:

  1. Remove the metal key from the new fob. Insert it into the ignition.
  2. Turn the key to position 1, and then back. Repeat this move five times fast. You should hear a small click each time you move to position 1, but the engine should never turn over.
  3. Remove the key and place it back in the BMW fob. Now, you’ll use the buttons on the fob to finish the process.
  4. Hold the unlock button down, then press the BMW logo three times in rapid succession. Then, remove your finger from the unlock button.
  5. If you have additional BMW keys that you need to program, repeat step four with each additional fob, within thirty seconds of syncing the original.
  6. Turning on the ignition will complete the syncing process for each of the fobs you’ve connected.

Syncing Additional Key Fobs with Your BMW

If you already have one or more working key fobs, but you’d like to sync additional keys, you can take the following steps to complete the process quickly:

  1. Take the working key fob into the vehicle and close all windows and doors. Make sure you have all the other unprogrammed key fobs with you before you start.
  2. Take the working key, insert it into the ignition, and turn it to position 1. You’ll hear a small click and the dash lights will turn on, but the engine shouldn’t turn over.
  3. Turn the key back and remove it.
  4. Now take the working key fob and hold down the unlock button. With the latter held down, press the BMW logo three times. Then release the unlock button. The doors will automatically lock and unlock.
  5. Repeat this process exactly, with each new key fob that you’d like to sync. The doors will lock and unlock automatically each time, and your new fob should start working right away!
