Hy-Ko Chip Keys



What are Chip Keys anyway?
ChipKeys also known as anti-theft auto keys contain a computer “transponder” chip in the head of the key programmed to your vehicle’s security system.  Duplicate keys for  your vehicle require programming this matching code in order to operate the vehicle.


Auto manufacturers began phasing these keys into production vehicles as early as 1995.  The vehicle’s anti-theft computer and the programmed chipkey help to contain or reduce auto theft numbers which in turn reduces insurance premiums.  


 How do they work?
The computer chip in the key holds a code similar to a password.  The computer in your vehicle reads the password in the chipkey, and if the password matches the vehicle password, the vehicle will start.  Otherwise, your vehicle will be inoperable.  This additional security is a proven deterrent to theft and contributes to lower insurance premiums on vehicles with this technology.


So that’s why the ChipKey costs more than a plastic-head auto key!
Yes, exactly.  The key isn’t just a key.  It is a high-tech device that communicates electronically with the vehicle’s engine computer with a unique security code.  The majority of newer vehicles use smart keys that contain special-coded computer chips.  The new anti-theft automotive computer technology is an expensive component which was designed to protect against vehicle theft.  Each ChipKey must be programmed to work with a particular vehicle.  Programming these keys requires specialized diagnostic equipment operated by trained technicians.


And, key fobs?
These are generally what is known as remote keyless systems (RKS).  It controls access to your vehicle without using a traditional mechanical key. 

It uses an electronic remote control as a key which is activated by a handheld device or (automatically by proximity). 

They contain a short-range radio transmitter, and must be within a certain range, usually (15-60 ft), of the car to work.  When a button is pushed, it sends a coded signal by radio waves to a receiver unit in the car, which locks or unlocks the door.    Modern systems implement encryption to prevent car thieves from intercepting and spoofing the signal.  


The function of a remote keyless entry system are contained on a key fob or built into the ignition key handle itself.  Buttons are dedicated to locking or unlocking the doors and opening the trunk or tailgate and more.


Remote keyless entry fobs emit a radio frequency with a designated, distinct digital identity code.
