The primary benefit of this is security. One thing with most of the thieves is that they are always aiming at the car owner and their property. It is beneficial to use these keys since they are only operating with a message sent to the vehicle. This is important as they will just need to use a button to lock and unlock the car door, trunk and even the engine. Being that they operate with messages you find that it is very hard to compromise. This is not the case with standard keys as they can be copied or simulated for forced entry. This is important as it has been able to reduce of cars getting lost and their owners found dead.
Apart from that, this system is convenient. Take a case of someone walking from the shop with two bags full of items and a car key in the pocket. It will be very hard to unlock the car trunk, and you will have to put your bags down to unlock the trunk which might give someone an opportunity to run with your goods. On the other hand, you will not have to put the luggage down to unlock the trunk as you will just press the button to unlock it.
Most of the people also prefer keyless entry since it is mistake proof. At some point you may find yourself that you forget to lock the car door when you are using standard. When you are caught in such situation, and you are using a keyless entry you will have to go back and lock the car even if it is raining or else someone may steal it. Without getting out in the rain you will lock the car door using keyless entry.
Most of the people also prefer keyless entry systems because of their safety. Besides rain, there are many things that your car can protect you from. When you are using the standard key it will be very easy for someone who is following you to catch up with you especially when you are being followed as you will have to remove the key to unlock the car. With keyless entry system you will easily escape dangers by unlocking the car door from a distance and slip into the car.
Besides, it helps in preventing key damage. One thing with standard keys is that they will always cause a lot of scratches on the keyhole areas.
