Car keys come in different types and have changed a lot since they were just a simple metal piece with several cuts. Today’s car key takes the form of a transponder chip and laser cuts. To be precise there are a total of seven types of car keys, let’s have a look at them one by one.
Metal keys
The most common car key in all times and still a working key for some older model cars. This simple metal key has been discontinued in modern cars due to their low security level.
Remote and key
As the name suggests this car key combines a remote control and an integrated key. You will find this keys in most of the cars running on the road.
Tibbe keys
These are special keys based on a specific key code that available in only Ford and Jaguar car makes. Introduced by Ford in 1982 the tibbe keys are high security keys that cannot be duplicated by anyone except the dealership.
Programmable remotes
These are one step ahead of the remote and a key type. Programmable remotes are mostly called self programmable and they aren’t actual keys. They are simply a set of buttons that are programmed for different functions for example to lock and unlock your car, set the alarm off or open the trunk. These remotes can be programmed or duplicated by a professional car locksmiths or any car dealer.
Transponder keys
Like remote transponder keys are also commonly used keys these days, introduced in 1990s and are similar to metal keys embedded with an electronic chip installed in the key handle helping it to communicate with the car computer. This happens when you insert the key to turn on the ignition the car’s immobilizer responds to the code from the chip inside the key.
Proximity FOBs
This is a new method of entering a car and getting it started. A proximity fob is a keyless car entry and ignition system which works within acceptable proximity to the car. When you reach within the required distance the car detects your fob presence and opens the door for you. This was introduced by Mercedes-Benz in the year of 1988.
Laser-Cut keys
These are high security keys with a unique precise cut on both sides of the key, this keys also have a built-in transponder chip and they are very hard to duplicate.
