Keys

BMW keys are special because they hold so much information. Below are answers to a few common questions about BMW keys. Video

Do my keys need to be charged?

• Yes, each key contains a capacitor and that is what powers the buttons for locking and unlocking, when you insert the key into the ignition there is a plastic ring piece that goes around where your key goes into your ignition, that is called the antenna ring, it read your EWS code (anti- theft code that allows you to start the car) and also charges up the capacitor via magnetic wave in your key.
• No, BMWs with the comfort access feature, which allows you to start the car without inserting the key into the ignition, have a replaceable battery and does not need to be charged. These get checked every two years when you come in for maintenance and are replaceable through our parts department here at the store!
