Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using an additional key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio signals at a low level. They have a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has proven to be an enormous success in preventing auto theft. It has also saved many car owners a lot of money as they don't have to replace their vehicles.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past, car thieves would use the flat screwdriver to push the ignition switch in your car to go into "on" mode or even hot-wire it in order to evade the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the specific frequency of the chip within the key. the full report in the car will recognize the key as being valid and will allow fuel flow, power the starter or begin the engine.
Based on the manufacturer, certain vehicles can only accept certain types of transponder chip. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your car's keys and remotes.
A good automotive locksmith will have a multi-vehicle programming device that can be used on many different models and brands of cars. This is a less expensive option than purchasing individual tools for every brand of vehicle. There are also specialised key programming tools for automobiles that are only suitable for one particular brand of vehicle however, they are less frequently used. The top automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose an established company that has this kind of equipment.
Key FOBs
As the name suggests, key FOBs house the transponder chips that can be programmed to allow your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons that you can push to activate features like trunk release, door locks or fuel flap control. Some fobs have additional functions that can be controlled by the button presses for example, the "smart" key fob that allows you to get your car into tight parking spots as you would with the Genesis GV60 or Tesla. Tesla or Genesis GV60.
While some replacement keys can be programmed by you using the aid of a user's guide, you'll often need an automotive locksmith to have a new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port under the steering wheel.
Today, most key fobs come with security features that make it difficult for criminals to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In most cases you can purchase an additional key fob at the dealer or other retailer and have it programmed by a locksmith for your vehicle to be compatible with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who produce the tools used by auto locksmiths to program their customers' keys.
While some of the aftermarket key fobs are advertised as compatible with any vehicle, most automotive locksmiths do not recommend using them because they will likely only work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.

This includes the labor cost to program the keyfob as well as any replacement parts.

This means that if you get your keys replaced, you'll have to have the new key fob programed to the car in order for it to work.
