What is a Transponder Key?
First, before we dive into the potential problems that can arise with
transponder keys, let’s review how a transponder key operates. The two
mechanisms previously mentioned include both the inner chip within the
transponder key itself, while the second is located within the vehicle’s
computer. These two components must be properly programmed to recognize
and match one another in order for one’s vehicle to turn on. This
prevents similar, but different keys from being able to operate a given
vehicle. One must have the proper car key, as well as a working
transponder signal for the car to start.
Potential Problems
When there is something wrong with a transponder key, the most common
symptom vehicle owners discover is that their car will not start.
Sometimes, the vehicle will start, but then stall and eventually stop.
Or, one final common symptom is that not even your car’s electrical
panel will light up. These three common problems may signal other issues
with your car, but it is possible that your transponder signal or key
is causing the problem. There are several reasons why these issues might
happen to vehicle owners and why their transponder keys may be to
blame.
Chip Damage
Transponder keys, just like any other sets of keys, often are
subjected to wear and tear. Key sets are tossed around in pockets or in
purses and may, on occasion, be treated more severely. Chip damage
inside of the transponder key is common with how often keys are used and
handled. Even though you may not be able to physically see the chip
damage within your key, a professional locksmith can open up your key to
confirm if that is the source of the problem and either fix or replace
the chip.
