Brother Tiger Share–BMW’s new 5 Series G38 upgrades the original four-door keyless entry system

August 16, 2024

One of the processes that must be done when using a car is ignition start, which is mainly divided into two types. One is the most primitive mechanical key start, and the other is the one-click start of the inductive key. The latter will be the mainstream. The one-button start function, also known as keyless start, can start the vehicle without inserting the key into the keyhole. This function will be more convenient to work with the keyless entry function, so that you don’t need to take out the key from getting on the car to starting the vehicle, and the whole process will be more elegant and elegant. First of all, the car key is not as simple as a traditional mechanical key. It has a smart electronic chip inside. The system uses wireless radio frequency technology and a vehicle identification system. When you step into the prescribed range of about 1 meter near the vehicle, the system can recognize you. You are the authorized driver and automatically unlock it, or the owner can press the unlock button on the door handle or touch the area to directly unlock it. After getting on the bus, the whole process is fast and efficient.
Keyless entry is also called comfortable entry. There are two common types of comfortable entry: two-door and four-door entry. Only one side of the driver’s seat carries very little. It is also easy to distinguish whether this car is comfortable or not in terms of appearance. There are buttons or strips of protrusions on the door handle. It is generally a locking area, and the unlocking area is inside the handle and is unlocked by induction.

Many car owners expressed their regret that they had not chosen to enter comfortably when buying a car, and could only choose to install it later. Most of the installed items were from the auxiliary factory. The price is a little cheaper than the original one, but the experience is much worse than the original one. Because of the need to install modules from the auxiliary factory and a large number of wire harnesses, the response speed will be half a beat slow first, and sometimes it will be insensitive. The most important thing is that it cracked the anti-theft system of the original car, which poses a great safety risk. To install the original factory’s comfortable entry, you only need to install the antenna and replace the original factory door handle. It is responsive and the original factory is stable. It is perfectly compatible with the original car system, so you don’t have to worry about vehicle safety issues.
