KEY PROGRAMMING
An immobilizer is an anti-theft mechanism that prevents a vehicle’s
engine from starting unless the correct ignition key or other device
is present. Most new vehicles have an immobilizer as standard
equipment. An important advantage of this system is that it doesn’t
require the car owner to activate it since it operates automatically.
An immobilizer is considered as providing much more effective
anti-theft protection than an audible alarm alone.
As an anti-theft device, an immobilizer disables one of the systems
needed to start a car’s engine, usually the ignition or the fuel
supply. This is accomplished by radio frequency identification
between a transponder in the ignition key and a device called a
radio frequency reader in the steering column. When the key is
placed in the ignition, the transponder sends a signal with a unique
identification code to the reader, which relays it to a receiver in the
vehicle’s tablet control module. If the code is correct, the tablet
allows the fuel supply and ignition systems to operate and start the
car. If the code is incorrect or absent, the tablet disables the
system, and the car will be unable to start until the correct key is
placed in the ignition.
