Transponder Chips
If your car was manufactured in the past 20 years, it is likely that it contains a transponder chip within of it. It’s the small piece of plastic in the head of your car key that contains 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 then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your car.
This is what prevents doing hot-wiring or altering the vehicle’s ignition system to get it started. The chip inside the car key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car key programer near me.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car doesn’t recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and an alarm. This is designed to discourage people from attempting to tamper with the vehicle, but it’s not a 100% security measure. A skilled and determined thief could still be able to bypass this system by employing a device designed to detect the signal.
As you can see there are quite few advantages to getting transponder keys. Every car owner must take this into consideration if they wish to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking space, today’s key fobs can also activate a heated steering wheel, or roll down all of the windows with a single button click. Many of these extra features may appear convenient however they could make it difficult for you to keep the track of your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted through an antenna in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
There are several ways to program a key fob depending on the vehicle’s make and model. Some cars allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press a key fob’s button, the microchip inside transmits an informational code to the car’s receiver that it is paired with. The receiver then compares the data with the ‘allowed signals’ stored in the key fob, and then opens or locks the car’s door. If the information doesn’t match the fob’s information, the car won’t be allowed to drive.
Once the car is connected to a specific fob, it only accepts signals from the device. This means that other fobs won’t work with the vehicle even though they appear similar. This ensures the security of the computer system of the car and prevents unauthorised key fobs from taking control of it.
Most dealerships with newer cars will only accept vehicles that have original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place with the knowledge to create the replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems — can be programmed by the consumer without the need for an authorized dealer.
