11 Methods To Totally Defeat Your Car Key Programmer
What Are Car Key Programmers?

Car key programmers are devices that can duplicate a transponder within the memory of a car. They are useful for replacing keys that have been stolen or lost. They can also be used to reset oil service lights as well as tire pressure warning lights and many other functions.

Most of these devices are bidirectional OBD II devices that work with a wide range of vehicles. Some, like the Autel MaxiIM IM608S II, provide an automated and supervised Smart Mode that aids novices, while experts can use Expert Mode.

The Basics

The process of programming a car key lets you to recode an uncoded chip for a replacement key to ensure that it is compatible with the settings of your vehicle. This allows the key to communicate with the vehicle, and also ensures that the key is capable of running and starting the engine. Although it is possible to accomplish this with a standard mechanical car key, modern cars require a device known as a "car key programmer." These are usually standalone devices but are sometimes integrated into more complex scan tools.

When it comes to selecting the most effective car key programming program for your needs, there are a few important aspects you should keep in mind. First, consider your budget. The cost of car key programming devices can differ, so it's crucial to find one within your budget. Before purchasing do some research on different models and read customer reviews. You might also ask other locksmiths or automotive professionals for suggestions.

Another thing to think about is the ease of use. It is crucial to choose an easy-to-use car key programer. Many are complex and require a long learning curve. Choose a program that has clear instructions and an intuitive program that can help you get started quickly. Finally, consider the variety of models the key programmer can support. It is crucial to locate a tool that covers an array of vehicles to be able to serve as a multipurpose solution for your business in the automotive sector.

It is important to check that the car you're considering has this feature before purchasing a key programmer. Certain cars come with "On-Board Programing" that allows you to create an entirely new car key by following a simple process. This is not a foolproof system, and you'll require the key(s) and vehicle in front of you, but it can be an effective method to save money on a professional service.

Method of EEPROM

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a permanent CMOS chip that is used to store information in computers and other electronic devices. It can be programmed with individual bytes, which are accessible via an address. Each byte can be either one or zero. When the byte is written to the chip, it becomes active and when it is read, the bits are decoded into instructions.

When writing data into an EPROM, both the source and drain are grounded. A high voltage channeled through the control gate travels through the silicon oxide to the floating gate and causes electrons to flow into it and become trapped. This causes the gate to change its content from 0 to 1. If the voltage is removed, the gate becomes uncharged and the contents of the EEPROM are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations and the statuses of remote keyless system components. They are also used to keep track of state between power transitions. This is essential for ICs powered by batteries because a sudden loss in power will cause the chip to reset.

There are several ways to reprogram an EEPROM. However, the majority of them require the vehicle to be in a specific state. For example, it may be necessary to disconnect the ECU from the battery, or to take the EEPROM out and connect it to the test board. Then, the contents of the EEPROM can be read using an EEPROM reader and transferred to a different chip.

It is a lengthy process, and it is difficult to obtain the correct data. Many people prefer having their vehicles reprogrammed by professionals instead of doing it at home. Find an auto locksmith that is reputable and has advanced tools who knows what they do. This will ensure that the key works and is programmed correctly. To avoid problems in the future it is a good idea for the locksmith to use genuine parts.

Onboard Programming

A car key programmer is a handheld tool used to program new fobs or remotes. They are used in the field by professional locksmiths to increase their efficiency, or by DIY customers to save money. Car key programmers are available in three different types that include onboard, OBD2 as well as EEPROM. Each has its own advantages and drawbacks. Onboard programming is the fastest method, however OBD2 and EEPROM may take longer. Onboard programming is fairly secure as long as correct procedures and methods are followed.

In the majority of cases, the key or fob will need to be programmed to communicate with the vehicle before it is able to start the engine. The electronic keys that are found in many modern vehicles are equipped with improved transponders that require a specific programer to work correctly. A professional can perform this task efficiently, often in less than one minute.


Connecting the device to an OBD2 port can aid in longer-lasting procedures. Certain vehicles may require EEPROM programming, which can take several days. This is why the majority of these tasks should be left to professionals who have access to the right tools, and who have an understanding of car safety systems.

You might need to add the capability to program car keys to your toolkit in three different situations:

A customer may ask for an extra key. Then, you may need to program an additional fob or key after replacing one that was lost. Third, you might need to do some no-start diagnostics on a vehicle that doesn't start with a certain key.

The addition of car key programming capabilities to your shop could also increase your profits by offering this service. A typical customer can pay between $50 and $75 for the service, depending on the model and make of their vehicle and whether they receive it from an auto dealership or through a professional. With the right information and some training you can become a successful auto key programmer and begin earning more money. You can then use this money to upgrade your tools and expand your business.

DIY Method

It can be a hassle to lose your car keys. Depending on the situation you might be able to replace your keys with an automotive locksmith or dealership, but it can take a long time. In the majority of instances, a transponder chip needs to be reprogrammed on the key. This requires knowledge and skills.

As such, it's important to consider the advantages and disadvantages of DIY car key reprogramming before attempting the task yourself. This process may appear simple however, it's difficult to execute correctly and could cause serious system damage if not performed properly. Therefore, it is always advised to consult a professional, and be cautious about DIY key programming.

There are a few ways to program a brand new car key. One method is called On-Board Key Programming. This involves inserting the new key into the ignition and then turning it on. After inserting the key you must wait for a few seconds and then switch it off. The reason is that the system resets its settings after a certain amount of time.

You will require a car key programer to perform this process. You'll need to select a programmer that is compatible with your car model. Once you've identified a compatible device, follow the instructions in the user's guide to correctly configure and use the device. Additionally, you should be aware that each vehicle has its own specific programming protocol, so it's important to follow the correct steps.

There are plenty of top car key programming tools on the market that can help you save money while remaining safe while driving. Autel MaxiIM IM608PRO is a good choice for shops who want to program a replacement key and restore immobilizer data. You can also count on Autel's excellent customer service team to assist you with any issues that might arise. This is an excellent option for auto locksmiths who are just beginning their careers. It can also be used as a backup plan in the event that the primary car key programer is damaged or lost.
