Does the BMW 525 not have a keyless entry system?

[McCarmen]

BMW 525 is equipped with a keyless entry system. Keyless entry system process: The keyless entry system is a key with an intelligent electronic chip. If the BMW 5 Series is equipped with a keyless entry system, when the key approaches the BMW 5 Series body, the doors automatically unlock and the anti-theft alarm is deactivated; when the key moves away from the BMW 5 Series body, the doors automatically lock and the anti-theft alarm is activated. Key maintenance precautions: Do not expose the key to temperatures below 0°C (too cold) or above 50°C (too hot), as this will significantly reduce the battery life. Store the key in a dry environment, as a humid environment can also decrease battery life. Do not place the key with hard objects, as this can scratch the chrome plating on the key. Do not place the key near high-power appliances such as televisions, microwaves, washing machines, or computers, as these devices can reduce the battery life of the remote control.

I think this issue depends on the specific year and configuration of the BMW 525. Older models, like the base version of the 525i from a decade ago, often don't come with keyless entry and require additional packages like the Comfort Package. Newer models might include it. From my experience, the keyless system is really convenient—it automatically unlocks when you approach the car, saving the hassle of pulling out the key. However, you should be aware of security risks, such as signal interference preventing the car from locking. I once almost forgot to confirm if the car was locked. The BMW 5 Series is quite tech-savvy overall, and higher trims like the 530 usually come with these features by default. When checking configurations, it's best to look at the production year and market version—official website materials are comprehensive. If you're on a tight budget and opt for the base 525, you might have to sacrifice some convenience. The owner's manual or a VIN query can quickly confirm the details. The system is easy to maintain but requires professional installation for modifications—don't attempt DIY fixes.

From a car enthusiast's perspective, let's talk about the keyless entry on the BMW 525: The core lies in the optional configurations of specific models. Entry-level 525s often simplify advanced features to reduce costs - keyless entry might only be available in luxury packages or M Sport trims. Higher-spec models like the 2023 525Li are more likely to have it as standard. In daily use, I've found this feature incredibly convenient - no fumbling for keys in the rain, just approach and pull the door handle. The technology works via RFID key chip recognition, though it can malfunction in areas with strong interference or when the battery is weak. BMW's trend is making digital key systems (including smartphone unlocking) standard on new models, but for the 525, it depends on your purchase configuration. My advice: always verify through the owner's manual or official configurator rather than guessing. Aftermarket solutions exist, but OEM retrofitting is more reliable. Overall, not all 525s have it - choosing the right configuration significantly boosts convenience.

The BMW 525 may not necessarily have keyless entry, depending on the configuration and model year. The vehicle manual usually indicates standard features, while unspecified ones might require optional packages. Newer models are more likely to include this feature compared to older ones. I find the system practical but with minor risks, such as electromagnetic interference causing unlock failures. Users should verify the VIN code or consult the dealer for accurate information. Regular inspections shouldn't be overlooked during daily use, as maintenance is straightforward.
