Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on your vehicle's model and manufacturer the process could be as simple as using a spare key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to guard against theft of vehicles. These are small computer microchips that emit low-level radio signals. They have an unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been a huge success in preventing car theft. It has also saved many car owners a significant amount of money since they don't need to replace their vehicles.
The principle behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In the past car thieves used an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode, or hot-wire it in order to evade the system. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit a signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip inside the key. The car's onboard computer will recognise that the key is legitimate and allow fuel to flow, power up the starter, or even begin it.
Some vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it is crucial to make sure that your locksmith in the automotive industry is equipped to program your car's keys and fobs correctly.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a far cheaper alternative than buying specific tools for each model of vehicle. These are less common, but there are specialised automotive key programmers that can only work on a specific type of vehicle. The most reliable automotive locksmiths will have the appropriate tools to work on any type of vehicle, so ensure you choose a reputable business that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to unlock doors and begin the engine with the push of a button ignition. There are also buttons that you can press to activate features such as door locks, trunk release or fuel flap control. Some fobs also 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 to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you with the assistance of a user's manual but you'll usually require an auto locksmith to get a brand new one programmed if yours stops functioning. This is because a professional has the right equipment and access to the tools for programming needed to connect your car's computer through the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features to make it harder for attackers duplicate and copy the signals that they transmit. They include pseudo-random sequence generators that generate a fresh unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy the replacement keyfob at a dealership or another retailer. The locksmith you choose to use will then program it to work with your car. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with third-party companies that produce the tools used by auto locksmiths to program their customer's keys.
Certain aftermarket key fobs can be advertised as being compatible with vehicles of all kinds. However, professional locksmiths recommend against using them because they're likely to function poorly or even not at all. Instead, they recommend purchasing fobs designed specifically for your specific vehicle so that you can be certain they'll function correctly and are less prone to issues such as interference or incompatibility. This will save money over time by avoiding costly repairs or replacements of your fobs.
Tool for Programming Vehicle Manufacturers'
Automotive technology has progressed a lot and modern vehicles require computers to function. One key element of this technology is a transponder chipset that needs to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to function. These key fobs have built-in security features that stop hot-wiring (like in a film) and the car won't start without the proper key.
These key fobs are a bit more complex than the mechanical keys and are the reason you'll usually find them in the hands of a reputable, professional auto locksmith. The cost of a key fob may vary based on the vehicle model and the key type however they usually cost between $85 and $400. This includes the labor required to program the key fob and the cost of any needed replacement parts.
Car key fobs are more complex because they use an operating system that communicates with the onboard computer of the car. The software blocks unauthorized access by only permitting the key to function if it has been programmed for the specific car. This means that if your keys replaced, you'll need to have the new key fob programmed to the car in order for it to function.
This is done by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool allows the locksmith to connect to the OBD port (OBD) within the vehicle and then enter an programming mode. The key programming device can be a handheld device that is affordable or sophisticated and capable of doing more than just program keys (like reading the eeprom file inside the ECU).
Some people attempt to program car key programming their keys on their own using these tools. However, this is best left to an experienced auto locksmith. It's easy to make mistakes with the software systems if you don't understand the nuances. This can lead to damage. It's important to keep in mind that a knowledgeable professional can help you avoid these problems.
On-Board programming
If your vehicle is old enough, you'll still have a traditional key made of metal to use to unlock the doors and turn off the ignition. Modern cars come with a transponder that must be acknowledged and accepted by the computer system to start. This is a further security measure to prevent thieves from stealing the car and then driving off with a stolen vehicle. A locksmith certified has the tools and software needed to program a key that can be compatible with your car's security system.
First, your locksmith will need to get a blank key that is compatible with the model and make of your vehicle. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will put the vehicle into an exclusive programming mode that allows the locksmith to add a new key into the system.
The key scanner is programmed to communicate with the computer of the vehicle to send the code. The computer will detect this code and include it to the list of approved key. In certain instances the scanner may also be able to erase keys that are stolen or lost from the system.
You can also program new keys with EEPROM. It is more complicated and requires a deep understanding of how electronic systems work. This is why it's best left to a professional that has a lot of experience working with these kinds of systems.
Locksmiths can program keys quickly with onboard programming. It takes as little as an hour if everything is done correctly. If the key isn't in right condition or the procedure isn't followed exactly, it can take as long as a half hour.
There are numerous key programmer scanners that support different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide selection of models for vehicles. There is no system that can program every vehicle. These devices are also expensive. It's a good idea to buy a programmer that receives regular updates as the manufacturer releases new technologies. Your programming machine will quickly become obsolete if you don't take this step.
