Looking at a specialized site can be a great, budget-friendly choice, but there are some factors to look out for as an informed customer.

Shopping Safely

When you view a Mitsubishi key seller’s website, you should be able to find the following information:

  • Copyright: Legitimate sites will often have “© Copyright 2021” at the bottom of the page.
  • Shipping details: The company should state the time and cost to ship and whether tracking is free or paid. As a bonus, free shipping can save you a good deal of money, particularly if your seller is overseas.
  • A number to call or email to contact: Ideally, there will be no need for you to contact your seller during the transaction. However, every reputable store should have email or call options for customer service. These days, an email address is more common than a customer service hotline.

If you search for a remote on an online marketplace — such as Amazon, Inc. — you might not be able to find all of these details. For example, there may be no email, number to call, or other forms of contact if the platform handles customer service. In this case, view the customer ratings to understand the seller’s legitimacy.

Mitsubishi Key Programming Options—Customer DIY vs. Professional Programming Services

Black and Silver Mercedes Benz Steering Wheel After receiving your Mitsubishi key, the next step is programming it to control your car. Most car remotes will require a professional service, so make sure you check your product’s specifications before finalizing your purchase. There are three different ways to program your Mitsubishi key fob:

1. Customer Key Programming (When Available)

DIY programming is the cheapest way to get a functional key fob, but you may not be able to find a programming tutorial for all Mitsubishi vehicles. Additionally, a customer cannot program most fob devices. You’ll have to access one of the other services below.

2. Dealer Programming for Mitsubishi Key Fobs

A Mitsubishi dealer will have the most experience in programming your specific key fob. If necessary, make sure your dealer will be willing to service you—some dealers will refuse to program aftermarket products. Mitsubishi dealers will be the most expensive way to program your replacement, but it’s also the most reliable way. If you can’t do it yourself or find a trustworthy automotive locksmith, a dealer is the best route, no matter the cost.

3. Using an Automotive Locksmith Programming Service

An automotive locksmith is simply a person or company that specializes in locks and keys for vehicles. They almost always handle electronics as well as regular keys due to the near-universal use of key fobs. Generally, going through an automotive locksmith will save you more money than using a dealer, making them the next best option budget-wise when DIY programming isn’t an option. However, not all locksmiths will have experience programming your device.
