Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the car's maker and model, the procedure can be as easy as programming onboard using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop software or hardware for locksmiths in the automotive industry.
Transponder Chips
Most newer cars use transponder chips to stop car theft. These are tiny computer microchips which emit radio signals of low-level. The microchips have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money since they don't have to replace their vehicles.
The principle of the transponder system is to make it impossible for thieves to open the doors of your vehicle without the correct key. In the past, car thieves would use an ordinary screwdriver to force the ignition switch in your car into "on" mode or even hot-wire it to bypass the system. These kinds of thefts have drastically decreased with the introduction of the transponder chip.
When you insert the transponder key in the ignition, the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will detect that the key is valid and allow the fuel to flow, then power the starter or begin it.
Based on the manufacturer, certain vehicles can only accept the specific type of transponder chip. This is why it is crucial to make sure that your automotive locksmith is equipped to program your car's keys and fobs correctly.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that is compatible with different models and car brands. This is a less expensive option than purchasing separate tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programmers that are able to only work on a particular type of vehicle. The best 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 implies, key FOBs house the programmable transponder chips that allow your car to recognize and unlock the doors, or start the engine using push-button ignition. You can also use the buttons to activate features such as door locks, trunk releases or controls for the fuel flap. Some fobs also have additional functions that can be controlled by the button presses like the "smart" key fob that lets you get your car into parking spaces that are difficult to access similar to a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the assistance of a user's manual however, you'll typically require an auto locksmith to get a brand new one programmed if the one you have isn't functioning. A professional locksmith is more equipped to connect your computer to the vehicle via the OBD port on the steering wheel.
The majority of key fobs today have security features that make it difficult for attackers to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators which generate a unique unlock code each time you press the button. This prevents attackers capturing and playing back the unlock signal to gain access to your car.
In some cases you can purchase the replacement keyfob at an authorized dealer or another retailer. Your automotive locksmith will then program it to work with your vehicle. This is due to the fact that most of the major US and Asian car makers use key fob programming protocols with third-party companies who make the tools that locksmiths for auto utilize to program keys for their customers.
Certain aftermarket key fobs can be advertised as being compatible with all vehicles. However, automotive locksmiths advise against using them since they are likely to work poorly or not even work at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you can be certain they'll function G28 correctly and are less prone to issues such as interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.
Vehicle Manufacturers' Programming Tool
The automobile industry has made significant strides in the last few decades. Today's vehicles are computer-driven. A transponder chip is an essential part of this technology. It needs to be programmed by a locksmith, mechanic, or dealer to work. Key fobs come with security features that prevent hot-wiring like in a film. The car won't start without the correct keys.
Key fobs can be a little more complex than a traditional mechanical key. This is why they are usually placed in the hands of experienced professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the key type however, they generally cost between $85 to $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
To make the process more difficult the car key fobs utilize a specific software system to work with the car's onboard computer. The software blocks unauthorized access by allowing the key to function if it has been programmed for the specific car. This means that if you need your keys replaced, you'll need have the new key fob programed to the car in order for it to work.
The most common method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. The key programming device can be an handheld device that is inexpensive or one that is sophisticated and capable of doing more than just programming keys (like reading the eeprom file in the ECU).
While some may try to program their own keys with these tools, this is an activity best left to an experienced auto locksmith. If you're not aware of all the details of the various software systems, it's easy to accidentally change settings that could cause damage to the vehicle. The most important thing to remember is that an experienced professional can help you avoid these problems.
On-Board Programming
If your car is older than you that you'll have a traditional metal key to use to unlock the doors and turn over the ignition. However, modern cars are equipped with a transponder chip that must be recognized by the computer system to allow it to start. This is an extra layer of protection that can stop car thieves from stealing a car and driving away with it. A locksmith who is certified will have the tools and software required to program a key that will function in your car's system.
Your locksmith will need to acquire an uncut key that is compatible with your vehicle's model and make. Once the key is received, your locksmith will link the programming scanner to the diagnostic port of your car. This will put your car into a special programming mode that will allow the locksmith to add a new key into the system.
The key programmer scanner communicates with the computer in the vehicle to transmit an electronic code. The computer will recognize this code and add it to the list of keys that are approved. In some cases, the scanner will also be able to erase lost or stolen keys from the system.
You can also program new keys using the EEPROM. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional who has extensive experience working on these types of systems.
Onboard programming is the most efficient way for a locksmith to program an entirely new key. When everything is done correctly, it can take as little as one minute. If the key is not in good working order or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are a variety of key programmer scanners that work with various vehicle models and makes. Both the Smart Pro and Autel IM608 Pro have become very popular among locksmiths due to their wide selection of vehicle models. However, neither will be able to program every vehicle in existence. Furthermore, these systems cost a lot. It's a good idea purchase a programer that is updated regularly when the manufacturer introduces new technologies. If not, your computer will become obsolete quickly.
