Most cars today have the option of remote keyless entry, it’s just that many people don’t really know how to make the most of it. The common questions that arise are what happens when I press all the buttons on the key. Many are also sceptical about the safety associated with such a key if it can open a door from over 20ft away. Many also wonder about the possibility of someone else being able to open the door of the car with a similar key.
There are two basic remote keyless entry devices that are in the market. The first is a fob that is on your key ring which will lock and unlock your doors. Many keys also come with a means to arm and disarm an alarm on your car. The other kind is a small controller that is usually hung from your sun visor that will help you open a garage door. They can be part of home security systems that are remote control based.
For the first kind, that is a fob with a keychain, works with a small radio transmitter. When you press the relevant button on the fob, it sends out a coded signal to the receiver which either in the car or in the garage and this triggers the action to be completed.
Security of course is a big issue with remote keyless entry car keys. If it were that simple, then people would be opening each other’s cars and this could be a huge security threat. There are however ways and means in which each key is personalized and does not work when it comes to another car. It all is based on the programming of the chip that is inside the key and its transmitter and receiver.
There are several advantages to using a keyless entry system for your car. For one it is an efficient means of securing your car. It is simple enough to use and easy enough to reprogram to suit your needs. It works as a means of entry into the car, a means to lock it and to trigger a theft alarm whenever required. All of these advantages put together make it an excellent means of car security. It is also compact and is easily incorporated into your key or onto the key ring that you have. Such electronically created devices often have a fool-proof level of efficiency to them.
