What Are Car Key Programmers? Car key programmers are devices that replicate a transponder into the memory of a vehicle. These are useful for replacing stolen or lost keys. They can also be used to reset oil service light as well as warning lights for tire pressure and many other functions. These are typically bidirectional OBD II devices, which can be used with a variety vehicles. Some, like the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode that aids novices, while more experienced technicians can utilize Expert Mode. The Basics Car key programming is a procedure that allows you to recode the chip that is blank in your replacement key so it matches the current setting of your vehicle. This allows the key to communicate with the vehicle and ensures the key is capable of starting and running the engine. While it is possible to accomplish this using a regular mechanical car key, modern cars require a device known as a “car key programmer.” These are usually separate devices, but can be integrated into more complex scan tools. There are a few factors to consider when choosing the best car key programmer. First, consider your budget. The cost of car key programmers can vary, so it's important to find one within your budget. Before making a purchase make sure you research different models and read reviews. You might also ask for suggestions from other locksmiths and auto professionals.

This is not a foolproof method, but you will still require the vehicle and key(s). The EEPROM Method EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a permanent CMOS memory chip that is utilized in computers and other electronic devices to store information. It is programmed to store individual bits of data that are accessed with an address. Each byte is either a 1 (or a 0). If a byte has been written to the chip, it becomes active. The bits are then converted into instructions when the byte is read. When writing to an EPROM, the drain and source terminals are grounded. A high voltage channeled through the control gate tunnels through the silicon oxide to the floating gate which causes electrons to flow through it and get trapped. This causes the gate's content to change from a zero to a 1. When the voltage is cut off, 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 status of remote keyless system components. They can also be used to keep the state of the system between power transitions. This is essential for ICs powered by batteries, as a sudden loss of power can cause the chip to reset. There are a couple of ways to reprogram an EEPROM. However, the majority of them require that the car to be in a specific state. It could be necessary, for instance to disconnect the battery and ECU or remove the chip and place it on the test board. The contents of the EEPROM chip could then be read by an EEPROM Reader and then copied onto another chip. It can be a lengthy process, and it is difficult to get the right information. Many people opt to have their cars reprogrammed by a professional instead of trying this at home. Find an auto locksmith who is reliable and uses advanced tools who know what they do.

In most instances the fob or key will need to be programmed to communicate with the vehicle before it is able to start the engine. The majority of newer vehicles have upgraded transponders on their electronic keys, which require a special programer to function effectively. A professional can complete this task swiftly, often in less than one minute. Connecting the device to an OBD2 port can help with the process of. Some cars might even need EEPROM programming, which can take days.

One method is called On-Board Key Programming. This involves inserting the new key into the ignition and turning it on.
