What is a transponder key?
A transponder key is a car key that has a transponder chip inside of
it. This is an additional security measure meant to increase the levels
of proper user verification. The chip gives off a signal that
communicates with your car’s transceiver. The transceiver is looking for
the correct signal, so if there is no signal or the incorrect signal,
the car will not start.
A car that requires a transponder key will not work without one. A
key without the proper programming will still open the car doors, and
trunk, but you will need the appropriate transponder key programming in
order for the car to start.
Do I need to program my transponder key?
If you want your key to work in the ignition of your car, you must
program the transponder key. Transponder key programming is not
necessary for every single car. Some older vehicles only use the
standard metal key with no supplemental e
Do I need to purchase a new key?
If you would like to have another key, you or your local locksmith
can make this purchase. In the event that you would like to purchase the
key yourself, be wary of secondhand keys. These will be near impossible
to recut, and are most likely already programmed. Once the transponder
key programming process has taken place, that chip cannot be
reprogrammed to work with another car. The key must be blank.
That means that there are no cuts made and that the transponder chip
has never been used. The key must also be appropriate for the car. If
the key does not have the proper shape, then it will not fit into the
keyway. Whenever you want someone else to do the work, trust the company

In the instance that you do not want a key that will start your car,
and all you are looking for is one that will open your exterior locks
(doors and trunk), there is no need to program a transponder chip. When
you have a transceiver in your car, there is no way to get around
transponder key programming without undermining your own security.
How do I know if I have a transponder key?
Take a look at your car key. There is the metal piece that you place
in the ignition (blade), and a larger flattened piece that you will use
to turn the key once it is inserted (bow). If the bow of the key is
covered in a plastic or rubber shell, then there is a good chance that
there is a transponder chip inside. To be certain that this is the case,
you can remove the plastic covering and look for the chip.
It is very important that you do not scratch or damage the chip
during this process because that will make the key unusable in the
ignition. You could also copy the key using a key cutter and see if it
will start the car. If you attempt to start the car with just a metal
key, keep the working key out of the vehicle, as this may give you a
false positive.
The most foolproof method is to call the automotive locksmith.
They can check to see if the key uses a transponder chip, and complete
the transponder key programming if you would like to make a new fully
functional key.
