Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's the small plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is received by a specific antenna that is attached to the ignition barrel. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from starting by hot-wiring or altering the key. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of these keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine, and will notify you via flashing lights and a siren. This feature is intended to deter people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and skilled criminal could still bypass this system by using a specific device that blocks the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding the car in a parking lot, today's key fobs can also activate the heated steering wheel or roll down all windows with a single push. These additional features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna within the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.
There are several ways to program a key fob based on your vehicle's model and make. You may be able to do it yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button it transmits an encoded code to the car's receiver it is linked to. The receiver compared this information with the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.
Once the car is paired with a specific fob it will only accept signals from that specific device. This means that other fobs won't work with the vehicle even though they look the same. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most newer car dealerships will only deal with cars with original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the knowledge to create an appropriate replacement fob is the service department of a dealer. Some aftermarket fobs, usually those for older models with less sophisticated systems, can be programmed without the need for a dealership.
