How cars without keys work

A world free of keys seems to be the new trend, and that is that the less articles we should take with us much better. 50 years ago no one would have told us that we could open and drive our own car without the need to use keys, a breakthrough for some. However, the more traditional ones, we can not avoid asking how is the operation of this technology and if it is really safe. That's why in .com we clarify your doubts and explain how cars without keys work with all the details.

Many car brands such as Renault or Ford already have several keyless or keyless models on the market, however for those of us who are used to opening the car with a remote control and turning it on with a key, we are curious about such automated dynamics.

The key is to take the control of the car in your pocket or purse and, without having it on hand, to open the vehicle and turn it on . This is possible due to a group of receivers that are located on the outside of the car and that are able to detect the proximity of the command and open the vehicle when we place our hand on the handle of the same and press the symbol usually marked with a key.

Once inside the vehicle we can turn it on by pressing a button, which will work because it detects that the command is in that physical space. That is to say, as it happens with the regular key, without control it will not be possible to do nad a.

To close the cars without keys we can leave the vehicle and press again the key symbol on the handle or, in some models, the car will close automatically when it detects that we have moved a certain number of centimeters.

Because this car system without keys works by frequency it is possible that it fails. In this situation, the command itself has a key that will open the vehicle and turn it on manually, which means that the vehicle can be accessed without problems in the event of unexpected failures.

Although for many the keyless system is completely new the reality is that the market is aiming more and more cars with this functionality, so it is possible that in some years we no longer remember the old key that we sometimes spent hours trying to find in the handbag.

This is one of the innovations of the industry along with other interesting advances such as solar cars or hybrids, which are gradually taking place in the automotive world.
