Wiki Article

Losing or damaging your car keys can be a frustrating and inconvenient experience. For Mitsubishi owners, the prospect of replacing and programming a new key might seem daunting and expensive, often conjuring images of costly dealership visits. However, understanding the intricacies of mitsubishi car key programming can empower you with knowledge of your options, potentially saving you time and money. This informative article delves deep into the world of Mitsubishi car key programming, exploring the different types of keys, the programming processes involved, the tools and equipment required, and valuable troubleshooting tips to get you back on the road swiftly and securely.

Understanding the Evolution of Mitsubishi Car Keys

Mitsubishi has evolved its key technology over the years, moving from simple mechanical keys to sophisticated electronic transponder keys and proximity fobs. Understanding the type of key your vehicle uses is the first crucial step in navigating the programming process. Older Mitsubishi models typically utilized standard mechanical keys that could be easily duplicated by a locksmith. However, modern Mitsubishi vehicles, especially those manufactured after the late 1990s, are equipped with transponder keys. These keys contain a microchip that communicates with the car's immobilizer system. Without the correct transponder code programmed into the vehicle's computer, the engine will not start, providing an added layer of security against theft. More recent models feature proximity fobs, which offer keyless entry and ignition. These fobs communicate wirelessly with the vehicle and require a more complex programming procedure. Identifying whether you have a basic mechanical key, a transponder key, or a proximity fob will dictate the programming methods available to you. Consulting your owner's manual is an excellent way to determine the specific type of key system your Mitsubishi vehicle employs.

Exploring Different Programming Methods

The method for programming a Mitsubishi car key varies depending on the vehicle's model, year, and the type of key. Generally, there are a few primary approaches:

Onboard Programming: Some Mitsubishi vehicles allow for a self-programming procedure, often referred to as onboard programming. This method typically involves a sequence of turning the ignition on and off, opening and closing doors, and pressing buttons on the key or fob in a specific order. The exact steps for onboard programming are highly specific to the vehicle model and year and are usually detailed in the owner's manual. While convenient, onboard programming may not be available for all Mitsubishi models, particularly newer ones with more advanced security systems. It's crucial to consult your owner's manual meticulously and follow the instructions precisely, as incorrect steps can sometimes lock the system or cause further complications.

Diagnostic Tool Programming: For many modern Mitsubishi vehicles, especially those with advanced security features, programming new keys requires the use of a specialized diagnostic scan tool. These tools, often used by dealerships and professional automotive locksmiths, can communicate directly with the vehicle's onboard computer system (OBD-II port). The diagnostic tool interfaces with the immobilizer system, allowing the technician to input the necessary security codes and program the new transponder chip or proximity fob to be recognized by the vehicle. This method is generally more reliable and can handle a wider range of Mitsubishi models and key types. However, it necessitates access to a compatible diagnostic tool and the relevant software and security credentials.

Locksmith Programming: Automotive locksmiths specializing in key programming offer a valuable alternative to dealership services. These professionals possess the necessary diagnostic tools and expertise to program Mitsubishi car keys, often at a more competitive price point. They can typically handle transponder keys and proximity fobs for a wide range of Mitsubishi vehicles. Furthermore, locksmiths can often come to your location, which can be particularly helpful if you have lost all your keys and cannot drive your car to a dealership. When choosing a locksmith, ensure they have experience with Mitsubishi vehicles and possess the necessary programming equipment. Inquiring about their credentials and reading online reviews can help you select a reputable and reliable service provider.

Dealership Programming: Mitsubishi dealerships have the official diagnostic equipment and software specifically designed for programming keys for all Mitsubishi models. While often the most expensive option, going to the dealership ensures that the key is programmed correctly and that you receive an original Mitsubishi key. This can be particularly important for newer vehicles with complex security systems where aftermarket keys or non-official programming methods might not be compatible or could potentially void warranties. The dealership will typically require proof of ownership, such as your vehicle registration and copyright, before programming a new key.

Essential Tools and Equipment

Depending on the chosen programming method, different tools and equipment may be required:

• Owner's Manual: This is your first and most crucial resource for determining if onboard programming is possible and understanding the specific steps involved for your Mitsubishi model.


• New Key or Fob: You will need a new, unprogrammed key or fob that is compatible with your vehicle's make, model, and year. Ensure you purchase the correct type of key (transponder or proximity) and that the frequency and chip type match your vehicle's requirements.


• Diagnostic Scan Tool: This specialized tool is necessary for programming keys on many modern Mitsubishi vehicles. It connects to the OBD-II port and communicates with the car's computer system. These tools range from professional-grade units used by dealerships and locksmiths to more affordable aftermarket options. However, using aftermarket tools requires caution and technical knowledge.


• Programming Software and Security Codes: The diagnostic tool often requires specific software and security codes to access the key programming functions within the vehicle's computer. These codes are typically obtained from the vehicle manufacturer or through authorized channels.


• Laptop or Tablet (Optional): Some diagnostic tools connect to a laptop or tablet to display the programming interface and guide the user through the process.

Step-by-Step Guide to General Programming (Illustrative Example - Consult Your Manual)

While the exact steps vary significantly by model, here's a general illustration of a potential onboard programming sequence (always prioritize your owner's manual):

1. Enter the Vehicle: Ensure all doors are closed and the vehicle is in park (for automatic transmissions) or neutral with the parking brake engaged (for manual transmissions).


2. Insert Existing Key: Insert your existing, working key into the ignition cylinder.


3. Turn Ignition On and Off: Turn the ignition to the "ON" position (without starting the engine) for a few seconds, then turn it back to the "OFF" position. Repeat this a specific number of times as indicated in your owner's manual (e.g., 3-6 times).


4. Remove Existing Key: Remove the existing key from the ignition.


5. Insert New Key: Immediately insert the new, unprogrammed key into the ignition cylinder.


6. Turn Ignition On: Turn the ignition to the "ON" position. If the programming is successful, the security light on your dashboard may flash or turn off.


7. Test the New Key: Attempt to start the engine with the new key. If it starts, the programming was successful. If not, repeat the process carefully or seek professional assistance.

Important Note: This is a highly generalized example. The actual steps for your specific Mitsubishi model will differ. Always refer to your owner's manual for accurate instructions.

Troubleshooting Common Programming Issues

Even with careful execution, you might encounter some issues during the key programming process:

• Programming Fails: If the new key does not start the vehicle after attempting the programming sequence, double-check that you have followed the correct steps precisely as outlined in your owner's manual. Ensure the new key is the correct type and compatible with your vehicle.


• Security Light Issues: If the security light on your dashboard remains illuminated or flashes rapidly after the programming attempt, it could indicate a problem with the programming process, an incompatible key, or an issue with the vehicle's immobilizer system.


• Inability to Enter Programming Mode: Some vehicles require a specific sequence of door locks, ignition cycles, and pedal presses to enter the programming mode. If you cannot initiate this mode, review your owner's manual carefully for the correct procedure.


• Diagnostic Tool Errors: If using a diagnostic tool, ensure the tool is properly connected to the OBD-II port, that you have the correct software and security codes, and that you are following the tool's instructions accurately. Software glitches or incorrect settings can lead to programming failures.
