Automotive Locksmith Key Programming

The majority of modern cars require some kind of key programming. Depending on your vehicle's model and manufacturer the procedure could be as simple as using an additional key to program the onboard computer or as complicated as OBD2 programming or EEPROM.

Most US and Asian car makers have programming protocols that they share with auto tool manufacturers so that they can develop software and hardware for locksmiths in the automotive industry to use.

Transponder Chips

Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio signals. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has proven to be a huge success in preventing car theft. It has also saved many car owners a significant amount of money since they don't have to buy new their cars.

The transponder system's basic idea is to make it impossible for thieves to open the doors of your car without the right key. In the past car thieves used an ordinary screwdriver to force the ignition switch of your car to go into "on" mode or even hot-wire it in order to bypass the system. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.

When you insert the transponder key into the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed to read the specific frequency of the chip within the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow, power the starter or start the engine.

Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it is important to ensure that your locksmith for automotive is equipped to program your car's key and fobs properly.

The majority of key fobs are equipped with security features to make it more difficult for criminals to clone and replicate the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.

In most cases you can purchase an additional key fob at the dealership or another retailer and have it programmable by your automotive locksmith to fit your specific vehicle.

They suggest buying fobs designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.
