The primary benefit of this is security. Normally, most of the thieves will be directing their attention towards you and your 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. With this, you would have managed to keep the thieves far from you and your [property.
Most of the people also prefer this system because of convenience. Take a case of someone walking from the shop with two bags full of items and a car key in the 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. This will be more simple and convenient if you are using the keyless system as you will just press the button for the trunk on your remote to unlock the trunk without putting bags down.
Apart from that, it is mistake proof. One thing that you should know is that human beings are destined to forget things at one particular moment. With this somebody may interfere with your car, and you will have to go back and lock it even if it is raining cats and dogs. Without getting out in the rain you will lock the car door using keyless entry.
The keyless entry system is also safe. Besides rain, there are many things that your car can protect you from. One thing for sure is that when someone is following you he may catch up with you when you are still looking for key to unlock your car. But with keyless entry you can unlock the door from a distance before you even reach the car which can make you escape someone who was following you.
With this system, you will prevent key damage. You find that standard keys always cause scratches around the lock area. 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.
