For BMW i1234567 Series X1iX3X4X5X6 Factory Comfort Entry Keyless Entry NFC Digital Key

BMW’s keyless entry feature, officially known as “Comfort Access,” is an advanced and convenient system that allows car owners to unlock, lock, and even start the vehicle without manually pressing the key button while carrying the smart key. This function is achieved by sensing the wireless signal of the key through the door handle and the low-frequency antenna inside the vehicle body.
