Understanding Vehicle Security

Car security can be divided into two categories – Car entry and Starting the car.

In most modern cars, you do not have to insert keys to open the doors since they have remote locking/unlocking. The older car remote entry systems used RF systems not fully secure as their signal could be easily captured and played back to unlock and enter the vehicle.

The modern entry locks use a more sophisticated rolling code system that generates a new code every time. The receiver on the vehicle also produces the same code, so both the electronic devices are synchronized. Infrared systems were also used by some European manufacturers who required pointing the remote towards the car to unlock. Still, most have been replaced with RF technology now.

Talking about starting the vehicle, traditional cars had a simple key lock system that could be unlocked from any similar key. This was convenient for thieves as it allowed them to drive away with any car easily. However, new cars have ECU technology and a transponder for added security.

Luxury vehicles can be coded according to the driver’s specifications. For instance, vehicles such as Rolls-Royce have a memory function, and as long as the driver inserts the key, the seats, headrest, mirrors, and steering wheel are adjusted according to the driver’s settings.

Manufacturers are now working towards removing the need for the key altogether and adding a fingerprint recognition system.

What is a Transponder?

Transponder technology is now apparent in many areas that require security access and are now popular in modern automobiles. New vehicle keys now feature a transponder chip, and as the key is inserted into the ignition, the chip is triggered by the radio frequency signal sent from the ignition barrel.

The chip then transmits a signal to the car’s ECU, which, when found to be correct, disables the immobilizer and starts the engine.

Can you program a new key fob yourself?

If it is only the key fob itself to unlock the car, you can most often program it yourself. However, programming a key for the start function is impossible without the right tools.

How much does it cost to reprogram a key fob?

Reprogramming a key fob for the lock and unlock costs nothing if you do it yourself in most car models. However, if you need to program the immobilizer function, you can expect a total cost of 200$ to 500$ for reprogramming at a workshop.

How to program key fob push start?

Most often, to program key fob push-starts, you need the right diagnostic tools because of the immobilizer, which only the authorized dealers have access to. If you just want to reprogram the unlock and lock feature, the method is the same as a standard key though; you just need to learn how to switch on the ignition properly.

How to erase key fob memory?

To erase the key fob memory, you need to use a suitable OBD2 diagnostic tool. Not all general scanner tools can do this, and you most often require a specific tool for your car model.
