BMW new cars come with 2 keys. Replacing the key battery: Gently press the small switch on the back of the key to remove the mechanical key. Then, use the mechanical key to open the key cover by inserting it into the notch beside the key and gently prying. After removing the key compartment cover, you will see the position of the old battery. It is recommended to use a small flat-head screwdriver for easier removal of the old battery. Ensure the new battery is installed with the positive side facing upwards, then reinstall the key cover and mechanical key, and confirm the key functions properly. Precautions for battery replacement: Do not use the wrong battery. The battery life of a smart car key is approximately 1 year. Battery consumption varies depending on the frequency of key usage. Different distances when using the key will also affect power consumption. Be very cautious when replacing the battery of a smart car key, as any mistake can burn out the circuit board inside the key.

I just picked up a new 5 Series, and BMW provided two smart keys. Both keys have identical functions, enabling keyless entry and vehicle start. I use one daily, while keeping the other at home as a spare. The keys are well-crafted with a small screen displaying vehicle status. I heard newer models like the X7 come with advanced touchscreen keys, but mine has the traditional style. It's important not to keep both together in case of loss—replacing a single key costs around 4,000-5,000 RMB at the dealership, plus the hassle of reprogramming the anti-theft system. It's wise to use a protective case to prevent scratches or accidental button presses. Also, the mechanical key is hidden inside the main key for emergency door access.

Last time when accompanying my friend to pick up the car at a BMW 4S store, the salesperson clearly stated that new cars come standard with two keys. Both are smart keys with remote control functions. My friend ordered a 3 Series and received two identical keys with no functional differences. The salesperson reminded us to test the unlocking and ignition functions of both keys on the spot. They specifically advised: it's best to keep one as a spare key and use only one regularly. Modern BMW car keys contain precision chips - losing one not only makes replacement expensive but also requires reprogramming and matching. Some newer models like the iX now support digital phone keys, but two physical keys must still be retained.

BMW's new car key system is quite advanced, with two smart keys as standard equipment. Each key can independently control the vehicle completely, from unlocking to starting without any issues. These keys come with encrypted chips and communicate with the car via radio signals. It's recommended to keep the spare key in a fixed location rather than carrying it around all the time. I know someone who keeps their spare key in the office, which is quite smart. Nowadays, car keys are powered by lithium batteries that typically last two to three years. The dashboard will alert you when the battery is low, and you can simply replace the coin cell battery yourself. Some high-end models come with keys featuring displays, but the quantity remains at two.
