Keyless access is the authorization of the car owner using a digital smart key or an additional immobilizer tag of the security system. Access is made contactless, the owner of the car just needs to approach it. The doors will be instantly unlocked, he will sit behind the wheel and, by pressing a button, will start the engine. This feature is available in premium cars that you can rent from Narscars. In our assortment there are also models of the middle and budget class, in which keyless entry is an additional option.
How wireless access works
To provide keyless access, a special chip is used, on which the access code to the car is programmed. The chip can be placed on different media:
- trinket;
- key;
- a plastic card;
- smartphone.
When the owner of the car moves away from him further than 2-3 meters, the signal is lost and all the locks in the car are blocked automatically.
The opening of the car occurs according to the following scheme.
- Get closer than 2-3 m to the car and press the button on the key fob. In this case, the system will give a signal to its unit located inside the car.
- The received signal will be processed by the system, in response it will send an encrypted message to the key fob.
- The keyfob will receive an encrypted signal and will send a response coded signal again at a different frequency.
- Upon receiving positive answers to all requests, the system in the car will allow the driver to open the door and remove the car from the alarm.
If contactless access is provided using a smartphone, then the exchange of signals between the units of the system is carried out via Bluetooth or Wi-Fi.
In more advanced contactless access systems, the parameters of the car owner are also taken into account. If, for example, its weight or height is very different from the data that was previously programmed, then the system requires an additional password to open the car.
In addition to opening and closing doors, the keyless entry system can perform other functions:
- start the engine without a key;
- memorize seat settings;
- raise windows;
- close the hatch when arming;
- contactless open the luggage compartment, etc.
In different brands of cars, this system is called differently. Mercedes-Benz calls it Keyless Go, Audi calls it Advanced Key, and Volvo calls it Keyless Drive.
The main pros and cons of keyless entry
The keyless entry system has the following advantages:
- helps to protect the car from theft through the use of a complex coding system;
- easily integrated with all systems available in the car;
- quickly starts a starter;
- allows you to block the doors and steering;
- Provides various vehicle information online.
Despite the many advantages, the keyless entry system has some minor drawbacks. Chief among them is the difficulty of making a new key in case of loss of the original. You can make a duplicate smart key only at the vehicle manufacturer's factory. If it becomes necessary to reprogram the chip itself, then you will have to contact the car dealer. To minimize the negative consequences of these shortcomings, you need to immediately order a duplicate smart key when installing such a system and leave it for storage in a safe place.
Frequently asked Questions:
What to do if the wireless access does not work?
There are several reasons why the system may not work.
- Discharging the car battery or batteries in the electronic key. To restore the system to working capacity, it is enough to open the car with a key fob and start the engine.
- Strong interference. The signal may be disturbed by other signals such as cell phones, TV towers, or repeaters near shopping malls.
- Malfunction of sensors in door handles. Corrosion can render them inoperable. Moisture and dirt can damage wiring.
- A device carried by the driver. Tablets and smartphones can emit signals that block the operation of the smart key, so they should be worn as far apart as possible.
In any case, if keyless entry fails to open the doors, the car owner has a physical key in the kit. Until the smart key is repaired, you can use the regular one.
What should I do if I forgot my key in the car?
The keyless entry system is intelligent. One of the stages of closing the car is to check the location of the smart key. If he remained in the cabin, it will not be possible to close the doors. The owner will be notified of his forgetfulness by a special sound signal. In some systems, a forgotten smart key is reported by an “emergency gang”.
Why won't the engine start?
Sometimes the keyless entry system may prevent the engine from starting because it cannot recognize the key. To start the car, just take it out of your pocket and bring it close to the start button. If necessary, it must be turned in different directions.
