When looking for a replacement car key or car key fob, there is an assortment of car keys that you can buy. It’s important to find a perfect replacement that is compatible with our car make and model because replacement car keys and key fobs vary enormously of their sophistication, security as well as cost:
Basic Car Key
The majority of early model car will probably just have a regular cut key .This is great as they are much easier to duplicate because they have minimal security capabilities due to being, well, basic! To improve the security of the car, many owners will likely have added some type of security system and / or keyless fob to hinder break-ins to their car or truck.
Car Key Remotes
Following on from the basic car key, a good number of vehicles will likely have some form of remote controlled that unlocks the car. Car key remote controls will often be battery powered and have got a press button on the car key fob, that will turn off the car’s security alarm.
These units will probably utilize an infra-red signal or a radio transmitter to transmit a coded signal towards receiver on your car. A standard issue is that you could get into your car using your car key however, if the car’s battery is dead, well then you wouldn’t be able to turn off the car’s alarm. It also been reported that some people that have this sort of device have not been able to gain access to their vehicles because of interference with the remote’s signal.
Car Key Transponder
This type of key is installed having an electronic transponder computer chip within the car key, or its key fobs. The way it works is that each computer chip transmits a completely unique computer code to the car’s immobilizer unit. In case the computer code doesn’t necessarily correspond with the code programmed within the immobilizer consequently the vehicle’s security system kicks and the car will just not start. The way that the transponder is built into the key you most likely won’t actually be aware that you’ve got this specific transponder processor chip within your car’s key.
Originally the majority of transponder keys had a fixed code that would transmitted the same code every time. However as car criminals have developed their tactic’s, so have the security experts. These days most car will have car key transponder with rolling code’s. These much more sophisticated transponder car keys can be found quite easily in shops or only. What makes these car keys more effective is that they produce a unique code each and every time the car key remote is used. Because of this they’re virtually impossible to clone so are generally much more secure.
Switchblade Car Key
To describe the switchblade car key could best to done by saying it is a key in which the base of the key retracts within the fob of the key. These are typically these have a small button that can clicked to open or release the key for you to use. The advantage of the Switchblade Car Key is that you are able to replace both the key or the fob on an individual basis if damaged or become faulty.
Smart Car Key
The term “key” in the word Smart Key is not 100% correct, simply because they aren’t actually a key as such. Smart Key have been developed allowing the key to remain in your bag, purse or pocket with no manual unlocking is necessary. Smart Keys were initially designed by Mercedes Benz for their S-Class series. Mercedes, when they first released the technology, reported it as “an electronic access and authorization of system”. By simply walking near the vehicle the key’s near field technology will trigger the car to unlock! Also, the vehicle’s immobilizer shall be deactivated and will also allow the car’s ignition to be started by pushing a button within the car (of course only if the smart key is inside the car as well). Some car manufacturers allow smart keys to lock that car’s door and activate the security alarm independently, one the driver gets out of the car and walks a specific distance away.
Although it may sound a little worrying being able to access and start up your car with a simple swipe of a car key fob smart keys, are incredibly secure and make use of constant rolling security codes (like the transponder key with rolling codes) instead of fixed codes to avoid break-ins. Because of this the codes involving the smart key and the immobilizer are completely random which results in there is significantly less possibility of having the ability to break into the vehicle.
Within a vehicle with a smart key security system integrated there will be a number of antennas that will recognize smart key if near by. The driver in most cases have the ability to press a button to unlock your vehicle, and in some cases a selection of custom adjustments will be carried out on the set up of the car, such as the heating and cooling, the position of the seating and even music personal preferences.
