The new energy BMW 5 Series 530 is currently known to come with a total of 3 keys. Prying Open the Back Cover: Use a flat-head screwdriver to gently pry open the back cover of the car key and carefully remove it. Replacing the Old and New Battery: Remove the old battery from the car key, then insert the newly purchased battery into the slot of the car key. When installing the new battery, ensure that the positive side of the battery faces downward. Proceed with replacing the battery. Reassembling the Key: Reattach the back cover of the car key. After installation, verify that all buttons on the car key function properly.

I've been driving a BMW 5 Series, and the new car came with two keys: one with remote functions and the other as a spare. The keyless entry system is incredibly convenient. When purchasing the car, the dealer confirmed this configuration as standard. The key battery life is quite good, but it's recommended to avoid prolonged exposure to direct sunlight and keep it dry. Once, I lost the spare key and had to spend 500 RMB to get a new one from the dealership, which was time-consuming and laborious. It's important to take good care of the keys—avoid placing them near mobile phones to prevent signal interference, and consider buying a key cover for protection. If multiple family members frequently use the car, getting a third key might cost extra, but the two keys provided with the new car are sufficient for daily use. The keys are made of durable, shock-resistant material.

With years of experience working at a dealership, I can confirm that the BMW 5 Series typically comes with two original smart keys, both capable of remote engine start. The internal circuitry of these keys is highly precise and pre-programmed to pair with the vehicle. Losing one requires professional tools for reprogramming, which can be costly. I recommend owners verify all key functions upon delivery, ensuring buttons work properly, and store the spare key in a secure location. The key battery lasts several years—avoid prying open the casing during replacement. Bonus tip: The key's chip is temperature-sensitive; avoid leaving it in hot car interiors. Repair shops have equipment to test key signal stability.

When I bought my BMW 5 Series, it came with only two keys - one for daily use and one for collection, simple and practical. The key design is minimalist but sturdy, with crisp button feedback. Don't lose the keys, otherwise it's a big hassle. Getting a new key requires going back to the authorized service center, which is time-consuming and not cheap. I make it a habit to regularly clean the key surface to avoid dust buildup affecting button sensitivity. The new car comes standard with two keys, no need for extra spending. The key size is just right for comfortable pocket carrying.
