Transponder based immobilization
is a very effective deterrent against auto theft.
Embedded in the head of the key is a radio frequency
"chip" which transmits a unique digital code to
the car. The car must be programmed to recognize
each key. The car is electronically shut down
unless a properly programmed key is used to start
the car.
This prevents a vehicle
from being stolen by any of the classic methods
of forcing, breaking, or lock manipulation. Stronger
and better locks are good, but there is nothing
which cannot eventually be broken or defeated.
Therefore, electronic immobilization is ideal.
It is safe to say that countless cars have not
been stolen because of transponder technology.
- The necessity of proprietary
diagnostic equipment for key programming.
- Establishing vehicle
specific PIN codes necessary for key programming.
- The use of proprietary
transponder chips.
- Using special encrypted
codes within the car's on-board system
Servicing most transponder
equipped cars requires some type of special
equipment. Locksmiths must make a substantial
investment to service transponder keys, and
the investment is ongoing with the continued
development of necessary new software and tools.
With some cars, locksmiths
may have the capability to program keys, but
essential information or PIN codes are either
cumbersome to get, or not available.
In general, transponder
immobilization systems are very effective against
auto theft. Cars will always be stolen by a
number of different methods, but transponder
technology is highly effective against the see,
break, drive away threat. However, look out
for this technology because it may become your
nemesis.
