Your
Chariot - Automotive security and Transponder Keys.
In
years past the odds against someone else's car key being able to
fit your car were not that great. Today the odds of the key to a
newer car fitting your car are very great. The newer
technologies being employed have however made even getting a
duplicate key to your car expensive and in some cases
challenging.
Automobile security has
changed dramatically in the last several years. We have gone
from the era when there were only 2000+ key combinations used
for every car of the largest auto manufacturer, to transponder
controlled ignition systems, that change electronic codes each
time you start your car. From the 30's to the 60's it was
somewhat common that you might know someone whose car key also
fit your car. Today just to obtain a duplicate key for your
car, can be difficult and expensive.
What are transponder
controlled systems and how do they work? The technology, it may
surprise you is really quite old. A "transponder" is in essence
a combination radio frequency receiver and transmitter. It
transmits a radio signal or binary code that can be picked up by
another receiver, if the codes or signals match, then some
action is allowed. Transponder technology has been used for many
years, and is still used today for aviation control. When a
pilot needs to be positively identified in a radar environment,
air traffic control will give him a specific code, that he will
dial into his transponder, the transponder will continuously
transmit that code, which will be received by the radar, a
labeled "blip" will appear on the air control radar that shows
exactly where that aircraft is. The miniaturization of
electronics now allows a transponder to be placed in the head of
your car key, this transponder transmits a specific code that is
received by a receiver in the dashboard of your car, if they
match, you can start your car.
Some of the problems
with current transponder systems include;
- No standard system
- at last count there are five different manufacturers of
these systems - how and who they allow to produce duplicate
or replacement keys seems to differ with each system.
- Some will allow
only the manufacturer of the car to service any part of
the system - this usually results in severe time and
expense penalties.
- Some will only
allow the auto dealers to service systems or provide
duplicate keys - again the result is more time and
expense.
- Some will allow
locksmiths to service systems and provide duplicate keys -
there usually is no time delay involved, because
specialized electronic equipment must sometimes be used,
it will still be more expensive than the consumer may
expect.
- Some systems do
not require the use of specialized equipment, but may
require that 2 or more original keys and the car be
present to allow "programming" duplicate keys to the
vehicle.
- Because of the
difficulty of explaining these systems, and the expense that
can be involved, some dealers and /or salesmen are reluctant
to discuss these systems. It is imperative that you know if
your vehicle is equipped with an ignition security system,
how it operates, and what is involved in obtaining duplicate
keys. You may have to demand that you be given this
information.
The benefit of these
systems is that having duplicate keys, does require that they be
programmed to the car, by some method. The likelihood of someone
obtaining an unauthorized duplicate is very remote.
At Whitlow's
Security Specialists, Inc. we have the specialized training and the electronic
equipment necessary to produce replacement or duplicate keys to
most transponder equipped vehicles. In most instances, this work
can be performed at your location, and usually on short notice.
