A keyless entry system is an electronic lock that controls
access to your vehicle without using a traditional mechanical key. It refers to
a lock that uses an electronic remote control as a key which is activated by a
handheld device near the vehicle.
A remote keyless system can include both a remote keyless
entry system (RKE), which unlocks the doors, and a remote keyless ignition
system (RKI), which starts the engine.
There is a small chip that creates the code that gets
transmitted from the key to the vehicle.
The controller chip in any modern controller uses something
called a hopping code or a rolling code to provide security.
The transmitter’s controller chip has a memory location that
holds the current 40-bit code. When you push a button on your key fob, it sends
that 40-bit code along with a function code that tells the car what you want to
do, lock the doors, unlock the doors or open the trunk.
The receiver’s controller chip also has a memory location
that holds the current 40-bit code. If the receiver gets the 40-bit code it
expects, then it performs the requested function.
Both the transmitter and the receiver use the same number
generator. In this way, the transmitter and the receiver are synchronized. The
receiver only opens the door if it receives the code it expects.
If your keyless entry remote and your car are no longer communicating,
you will have to reprogram your car’s keyless entry system.
Carless entry reprograming require special equipment. You
will need to contact your local dealer or Townsville Mobile Mechanic. If you
have any problems with your keyless entry Townsville Mobile Mechanic can help.
