As technology becomes more advanced the demand for building sophisticated systems has increased over the years. These technological advances have revolutionized various industries including the locksmith industry. In this article you will learn about the technology called EEPROM programming, an alternative method of key making.
Everything you own is an invaluable asset, so are your cars! The modern day car lock systems are equipped with various digital components exclusively designed to secure the cars. It is not an easy option to get a duplicate key because, keys have unique codes and require programming to link them to the vehicle.
Automotive locksmiths in Portland encounter a lot of vehicle security issues. The most common customer problem is losing the key. It is not so easy to get key duplication because the modern-day car lock systems are automated and you will not recognize the importance until it’s lost or stops working.
Most of the car keys stops working either due to physical damage or technical issue. when this happens, your vehicle fails to recognize the unique code of the key, and you have to get it reprogrammed.
So, it is important to either have a pre-coded key (in most of the cases is not available) or to opt for EEPROM method, an alternative form to create new keys when required.
What is EEPROM?
Among various electronic component in the vehicle, one of the component with memory part which stores the key data sequence is called as EEPROM.
EEPROM stands for Electrically Erasable Programmable Read Only Memory. It is a type of non-volatile memory chip designed to provide a piece of specific information to the user. Locksmiths use this technology to solve the lost key problem, it allows the user to erase the content and reprogram by using specialized tools and pulsed voltage. And the procedures followed to make the keys using EEPROM is called an EEPROM method, an alternative form for key making used for automotive locksmith services.
Applications of EEPROM:
- EEPROM is used in computers.
- It is used to integrate remote keyless systems and microcontrollers.
- It is used in certain vehicle immobilizer systems and other electronic devices to store minute amounts of data.
Benefits of EEPROM
- The method of erasing is electrical and immediate.
- It gives you the scope to re-program EEPROM an unlimited number of times.
- EEPROM method helps to erase entire contents of EEPROM and particular byte as per selection.
- It is very easy to program and erase the contents of EEPROM without removing it from the board.
- It is used to change the data, without using additional components.
- It is the process of creating a key from the information enclosed in the vehicle immobilizer module or ECU.
- And to run this programme, you need to have a locksmith kit as it uses the kit to read the data from the EEPROM and save it to a file.
- Once the file is generated, it is passed to a Transponder Programmer or Key Cloner which processes the file and creates a key.
- There are several transponder programmers (Tango, Zed-Bull, Mira Clone, AD900) that are capable of creating from the EEPROM data file.
How does EEPROM work?
To conduct EEPROM work, we must remove the module from the vehicle and locate the chip where the data is stored. And once it is located, we can read it in or out of the circuit.
The next step is either replace the data with a fresh file, read the EEPROM data to produce an existing transponder chip, or add values to the ROM for the transponder. Reading the chip in the circuit is always the preferred method.
If you are using a programmer that doesn’t control variable supply voltage you may end up with power up other components in the immobilizer. And that can cause a barrier to collect the EEPROM data. In these circumstances, you either need to lower the voltage supply, or simply short the oscillator out and if you don’t find this option as feasible, you must remove the chip and read it out of the circuit.
Once the data is read, we have to create a course of action to create a programmed transponder that helps to start the vehicle or manipulate the data as needed to add our chip to the immobilizer.
After reading the data and interpreting it we need to save the data back to the chip or prepare the blank transponder as needed. Finally, the immobilizer is installed back in the vehicle and ready to hit the road.
Vehicle brands which require EEPROM:
Why do you need EEPROM?
You need EEPROM for key generation and car key programming. The goal is to make sure that your vehicle is operating safely and prevents theft.
To implement this programme, you need to have the knowledge, skillset and the right tools else, your results may not be what you need them to be. And a proper automotive key generation is not possible without proper programming system access like this.
