A keyless entry system or a push-to-start system can save time until something breaks down, such as the key fob dying or a replacement being needed, a regular key differs from a smart key because this one has a built-in technology which lets a user unlock his car without inserting a regular key into a lock. This is a brief guide on how a smart key works and how to deal with some related problems. See our car key replacement service. We also handle key fob programming.

A smart key interacts with a car via a short-range wireless communication. Once a car is recognized by its key fob, users can enter the vehicle by touching the door handle and starting the engine with one press. While the car and key are located near each other, you will be able to operate it by touching it.
When the battery of a key fob runs out, you will still be able to start a car in most cases. Cars have some alternatives to the use of keys for starting, such as placing a fob next to the start button and pressing it. In addition to that, any key fob has an alternative lock mechanism that opens a door physically.
Many people confuse these items, but each one means something different. The term 'smart key' refers to a key which unlocks a car and enables a user to start it by pressing buttons. 'Transponder key' means inserting a key and starting an engine as there is a chip embedded. 'Remote', in turn, only opens and closes car doors.
The process of replacing a smart key requires more than cutting one, since you need to program it first so it could interact with your vehicle's security system. For example, it may need to be installed while all other keys are located next to it. Thus, smart keys tend to be rather pricey when compared to conventional car keys.
Because of the fact that a smart key constantly transmits a signal to a car, it can sometimes become a target for a criminal attack, however if you keep a key in a signal blocking purse, it becomes significantly harder for potential thieves to locate it.
As it has been mentioned above, smart keys are quite pricey, meaning that getting a new key fob can be rather costly, therefore having a spare one at hand saves you both time and effort should something happen.
