The German car giant loves its key fobs to start its cars. It’s been doing keyless start and entry for 20+ years. BMW key fob batteries need replacement every 3-5 years depending on usage. I got 5 years from my first battery for my X3 before needing to replace it.

  1. Apr 10, 2020 Maybe the key range is not very good. Or you may have a warning symbol on your dashboard. You will get a warning on your instrument cluster saying remote control battery discharged. To fix these problems you will need to replace the dead key fob battery. Once the BMW key fob battery dies, the keyless entry remote will stop working.
  2. The new battery will become overcharged as the car still thinks the old battery is installed. This can potentially cause damage to the car’s alternator. Your car may also throw off warning lights as indicators of these issues. Who can register or program a BMW battery? Any BMW dealership will be able to program or register your new BMW.

  4. One of our X3's fobs gave a low-battery message at about 17 months. The other one started at about two years old. Newer BMW fobs have motion sensors in them. They don't work unless they've been moving recently. That's to prevent those car thieves from pinging your key fob when it's sitting on the hall table inside your front door.

How much does it cost to replace a BMW car key?

BMW car keys must be programmed, this is usually done at a BMW dealership. When I lost a key, it cost roughly $400 to have the dealership program a new key. I had to give them a copy of my drivers license and registration as well. Not cheap.
