Most of the people prefer this system because of the security. One thing with most of the thieves is that they are always aiming at the car owner and their property. One thing with keyless entry is that they operate with the 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. One thing that is sure of is that it is very hard to compromise such systems since they operate with messages. Unlike standard keys that can be copied or simulated for forced entry. This has made it very hard for thieve to access their vehicles or their properties.
Most of the people also prefer this system because of convenience. 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. 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.
Safety is another benefit of keyless entry system. Most of the people always think that their cars can only prevent them from rain, but they can also use it as a place to hide. 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.
Another benefit is that it prevents key damage. One thing with standard keys is that they will always cause a lot of scratches on the keyhole areas. 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. But through press buttons, your car paint will always be in good condition.
