10 Wrong Answers To Common Automotive Locksmith Key Programming Questions: Do You Know The Right Answers?
Automotive Locksmith Key Programming
Modern cars need some form of key programming. Based on the model and manufacturer, the process may be as simple as using a spare key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers share their programming protocols with auto tool makers in order to create tools and hardware for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. They have a unique serial number which authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be an enormous success in preventing theft of cars. This technology has also helped car owners save a huge deal of money since they don't have to buy new vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to start your vehicle without the correct key. In the past, car thieves would simply push your car's ignition switch into the "on" position using the flat screwdriver, or make use of hot-wires to bypass the system altogether. These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The computer onboard of the car will recognize the key as being valid and will allow fuel flow, power the starter or begin the engine.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it's important to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs correctly.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that can work on many different car manufacturers and models. This is a cheaper option than purchasing separate tools for each brand of vehicle. These aren't as popular but there are automotive key programmers that can only work on a specific brand of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Make sure you select an established company that has this type of equipment.
Key FOBs
As the name suggests, key FOBs are home to the transponder chips programmable that allow your car to recognize and unlock the doors, or start the engine using a push button ignition. There are also buttons that you can push to activate features such as trunk release, door locks or control of the fuel flap. Some fobs have additional functions that can be controlled with the push of a button, such as a "smart" key fob that allows you to bring your car into tight parking spots similar to the Genesis GV60 or Tesla. Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the help of a user manual however, you'll typically need an automotive locksmith to get a brand new one programmed in case yours stops functioning. A professional locksmith is more equipped to connect your computer to the vehicle via the OBD port under the steering wheel.
Most key fobs today include 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 different unlock code each time you press the button. This is to prevent attackers from capturing and playing back the unlock signal in order to gain access to your vehicle.
In some cases you can purchase the replacement keyfob at an auto dealer or other retailer. The locksmith you choose to use will then program it to work with your car. This is because most of the major US and Asian car makers share their key fob programming protocols with third-party firms that create the tools locksmiths for auto use to programme keys for their customers.
While some aftermarket key fobs are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them as they are likely to function poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less susceptible to issues like interference or incompatibility. This will save you money in the end by avoiding costly repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made huge advances in the last couple of decades. Today's cars are computer-driven. One of the most important components of this technology is a transponder chipset that must be programmed into the vehicle by an expert locksmith or dealer/mechanic in order to function. Key fobs come with security features that prevent hot-wiring like in a film. The car will not start if the keys are not correct.
Key fobs can be a little more complex than a standard mechanical key. This is why they're usually handled by experienced professional auto locksmiths. The cost of a car key fob varies according to the type and model of key, but it is typically between $85 to $400. This includes the cost of labor to program the keyfob and any replacement parts.
To complicate the process, these car key fobs use a special software system to work with the car's onboard computer. The software prevents unauthorised access by only allowing keys programmed specifically for a particular car to work. If you decide to replace your keys, you'll have to program the new key fob to the car in order for it to function.
The most popular method to do this is by using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter a programming mode. The key programming tool can be a simple handheld device or a more expensive one that can perform many things that go beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people attempt to program their keys by themselves using these tools. However it's best to leave this task to a professional auto locksmith. Unless you're familiar with all the aspects of the various software systems, it's very easy to accidentally change settings that could damage the vehicle.

If your vehicle is older than you, you'll still have a traditional key made of metal to use to unlock the doors and turn off the ignition.

This will put your car into an exclusive programming mode that allows the locksmith to add a new key to the system.
The key programmer scanner communicates with the computer in the vehicle to transmit an electronic code. The computer will recognize the code and add it to the list of approved keys. In some cases the scanner will be able to erase keys that have been stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of electronic systems. It is best to leave it to a professional with knowledge of these systems.
Locksmiths can program a key quickly with onboard programming. When everything is done correctly, it can take just one minute. However, if the key isn't placed in the correct condition or the procedure is not followed exactly, it can take up to an hour.
There are numerous key programmer scanners available that support different vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicle models. There is no system that can program every vehicle. These machines are also quite expensive. It is a good idea to buy a programmer that will get regular updates as the manufacturer releases new technologies.
