BMW 118D Digital Key & Auto Door Tuning Review
BMW 118D digital key upgrade offers keyless entry via Bluetooth for a more convenient driving experience.
Upgrade Your BMW 118D with a Smart Digital Key System
Imagine your BMW 118D unlocking as you approach and locking as you walk away. The digital key installation we're reviewing today makes this a reality, offering a sophisticated Bluetooth-based system that mimics the convenience of factory-installed comfort access options. This upgrade is perfect for 118D owners who desire enhanced convenience without the premium price tag of original BMW options.
Understanding Digital Key vs. Factory Comfort Access
It's important to distinguish between BMW's factory 'Comfort Access' and aftermarket digital key solutions like 'Keypl2'. Comfort Access is an integrated factory option, often costing a significant amount when purchasing a new vehicle. Keypl2, on the other hand, is an aftermarket system utilizing Bluetooth technology that can be retrofitted to existing vehicles. While both offer proximity-based automatic locking and unlocking, Keypl2 provides a more budget-friendly alternative. A key advantage of Keypl2 is its independent operation; it functions as a separate module, ensuring no conflicts when the vehicle is serviced at a dealership.
BMW 118D Digital Key Installation Process
The installation begins with carefully disassembling the original smart key. The internal PCB board is then modified by precisely soldering wires for power, door lock, door unlock, and trunk signals. This intricate wiring ensures the new digital key system integrates seamlessly without interfering with the car's existing electronics.
Next, the main ECU module for the digital key system is installed. Its placement is flexible, often situated within the glove compartment or other discreet locations like the center console or under the dashboard, preserving the vehicle's interior aesthetics. Once the ECU is connected, it pairs with your smartphone via Bluetooth, enabling full digital control of your vehicle.
Upon successful pairing, the system detects your smartphone's Bluetooth signal as you approach. Within a set range, it automatically powers the smart key, unlocking the doors. As you move away, the power is cut off, conserving battery life. The system is powered by an internal lithium-ion battery, and the proximity range can be customized to your preference.
Enhanced Convenience with NFC Card Option
For added versatility, the Keypl2 system offers an optional NFC card. This card functions like a physical key, allowing you to lock and unlock the car by tapping it on the windshield where the ECU module is mounted. This is particularly useful for valet services, as you can hand over the NFC card instead of your smartphone. Multiple cards can be issued for family members.
If the NFC card functionality isn't required, the ECU module can be hidden away, such as inside the glovebox, without affecting the system's performance. This ensures a clean look while retaining all the advanced features.
