The BMW E90 introduced Comfort Access, a keyless entry and start system, enhancing convenience for drivers. This innovative technology allows drivers to unlock and start their vehicle without using a traditional key. The system utilizes a specialized key fob containing an ID sensor.
How E90 Comfort Access Works
The E90’s Comfort Access system functions through radio frequency identification (RFID). The key fob emits a unique signal recognized by the car’s sensors when within a short distance, typically a few feet. Upon recognizing the signal, the car automatically unlocks the doors. Once inside, the driver simply presses the start/stop button to start the engine, eliminating the need to insert a key.
Comfort Access integrates seamlessly with BMW’s key memory system. This feature automatically adjusts the driver’s seat position, door mirrors, climate control settings, and radio presets to the saved preferences of the key holder. This personalized experience ensures a comfortable and customized driving environment from the moment the driver approaches the vehicle.
Locking and Security with Comfort Access
Locking the E90 with Comfort Access is equally effortless. After exiting the vehicle and closing the door, the driver simply touches a designated area on the door handle. This action triggers the system to automatically lock the doors and secure the car. The system also incorporates a safety feature that prevents locking if the key fob is detected inside the vehicle, alerting the driver to retrieve it.
Backup Functionality
In the event of a system malfunction, a backup slot located in the instrument panel allows the driver to insert the key fob. This action enables the vehicle to start and operate conventionally, ensuring uninterrupted functionality. If the key fob battery is depleted, the vehicle may not respond to the Comfort Access features, so replacing the battery as needed is crucial. Additionally if the key fob is left inside the car, the doors will not lock providing a warning to the driver.
Benefits of E90 Comfort Access
Comfort Access offers several advantages:
- Convenience: Keyless entry and start simplifies the process of accessing and operating the vehicle.
- Personalization: Integrated key memory ensures a customized driving experience.
- Security: Automatic locking enhances security and reduces the risk of accidentally leaving the car unlocked.
- Backup Functionality: The system provides a fail-safe mechanism in case of malfunction.
Comfort Access significantly enhances the overall driving experience for E90 owners by providing a seamless blend of convenience, personalization, and security. The system exemplifies BMW’s commitment to innovation and driver-centric design.
