The primary benefit of this is security. You find that there is an increased number of thieves who are always aiming at taking your valuables and even robbing the property owner. It is beneficial to use these keys since they are only operating with a message sent to the vehicle. As a result, they will be in a position to operate their vehicles by just press a button to unlock and lock the door, trunk, and even the engine. With messages as a media of communication it will be very hard for thieves to compromise such systems. Unlike standard keys that can be copied or simulated for forced entry. With this, you would have managed to keep the thieves far from you and your [property.
The other thing is that it is convenient. You can try and imagine a situation where you are walking from the shop carrying two bags full of items with a car key in your pocket. With standard key and such a load you will have to put the load down to get a room to unlock the trunk which might give a thief opportunity to run with your bags. But with keyless entry you will safely put your goods on the trunk by just press of the trunk button on your keyless remote.
Apart from that, it is mistake proof. It is normal that you may forget to unlock the car door when you are using a standard key. In such situation, one may steal your car, and if it is not stolen, you will have to go back and unlock it even if it is raining. This will be very simple if you are using keyless entry as you will lock the car door from the house.
The keyless entry system is also safe. You should know that the car can not only protect you from rain but other disasters as well. In cases of emergency you the chances of you being caught before you get in the car will be high since you will have to remove the car keys to open the door. Unlike keyless entry which will allow you to unlock the door at a distance and slip into the car.
Another benefit is that it prevents key damage. You will experience a lot of scratches around the key lock area when using a standard key. This is not good as it will interfere with your car painting which will make some parts of the car to look old while others are still new. You can prevent this by installing keyless entry system which is free from such scratches.
