Reviews & Comparisons: Top 7 Car Key Programmers on the Market in 2022

Car key programmers are an important part of any mechanic’s tool set, whether you’re a professional or a DIY repairman. But, there are a lot of key programmer options on the market. Some key programmers are single-purpose, focused exclusively on generating new keys. Others include a range of diagnostic and service functions so they’re helpful all-in-one tools for any garage.

Let’s discuss why a car key programmer is so important and the top 7 products currently on the market for mechanics.

What is a Car Key Programmer?

Car key programmers allow mechanics to program an electronic key to work with your car. While keys can be obtained from a locksmith, mechanic, or dealership, they will need to be programmed either way. Having one in your repair kit can help save you the time and hassle of getting a new key from a locksmith if yours is lost or broken.

Drawbacks

Drawbacks

While this key programming tool has a wide range of special features and benefits, it still has it’s individual drawbacks including:

  • Won’t diagnose all engine modules: ​While it will diagnose a large amount of engine models, it does have its limitations.

ECU programming compatibility is still limited: This is an OBD2 tool, so it won’t work with other car systems.

4. FICBOX 4D Chip Keymaker/Programmer

The FICBOX 4D Chip Keymaker/Programmer is one of the most affordable on the market, so it makes a great tool for home mechanics that don’t mind the limited features. Some of the key features to this tool include:

  • Affordable Key Programming: If the models above are outside your budget, consider the FICBOX 4D Smart Key Maker. It can program new keys for Toyota and Lexus vehicles in about 20 seconds. Best of all, it does so without an immobilizer disrupting the car’s anti-theft protocols.
  • Great for Home Mechanics: While this tool won’t necessarily help you in a professional setting, it is the perfect key programmer for a home mechanic with Toyota or Lexus vehicles. 

The FIXBOX Keymaker also doesn’t have any service, diagnostic, or programming functions. That’s not surprising for the price, but it’s something to keep in mind. For making new keys, this is a fast and functional device, but don’t expect it to do anything beyond that.

  • Efficient Key Programming: The Autel MP808K can effectively program key fobs for a wide range of vehicles. It also supports ECU coding.

Its IMMO functionality is a bit limited, and on some vehicles more than others.
  • OEM-Level Diagnostics: Along with full OBD2 support, the MP808K can perform bi-directional tests of components. This is very useful for diagnosing mechanical issues and very helpful when it’s time to make repairs.
  • Full Service Functions: The capabilities of the MP808K go beyond any other scanner you’ll find at the price. It’s the best key programmer for all-in-one functionality. Among its 23 service functions are DPF regeneration, ABS bleeding, transmission or throttle adaptation, and injector coding. 

The Autel MP808K is the best diagnostic scanner with key programming abilities, but it’s not a dedicated key maker. Because of that, it’s missing some functions you’ll get from other professional key programmers.

  • Service and key programming functions not supported on all vehicles: You may find that this tool does not perform key programming functions for all vehicle manufacturers. However, it will work well for the following car types: Dodge, Toyota, Suzuki, Acura, Honda and Nissan.​​

6. Autel MaxilM IM608 Key Programmer

The Autel MaxiIM IM608 is a great tool to use for professionals. While it does have a higher price tag (upwards of $3,000), it does come with a wide range of features including:

  • Guided Key Programming: The Autel MaxilM IM608 gives users full access to key programming and IMMO functions.

This gives you more room to view diagnostic data and a clearer picture of your vehicle’s health. It includes both Smart and Expert modes, too, and has other helpful extras, like a built-in camera and flashlight.

The Autel MaxilM IM608 is an advanced key programmer and diagnostic scanner with all the functions a professional needs, though it’s likely outside the budget of hobbyists and DIY-ers.

While the list of special features of the Autel MaxiIm IM608 is comprehensive, it does have it’s drawbacks including:

  • High price: The price of this tool is usually between $3,000-$3,500. While the long list of features can justify the price for some repairmen, this is not a tool for the casual home mechanic. 
  • Unit is bulkier and requires more power: The bulky nature of this key programming tool makes it difficult to store. Additionally, the amount of power that it requires is much higher compared to the other key programming tools on the market. 

7. Carrfan CK-100 Car Key Programmer

The Carrfan CK-100 is a simple tool – it’s only purpose is car key programming and deactivating. While it’s missing some of the diagnostic features of the other models, it does have some key features including:

  • Compatibility: ​The only thing to be aware of before you buy the Carrfan CK-100 is that its compatibility is limited. While it supports key programming on more than 25 manufacturers, it won’t read PIN data from all of them. Make sure you check that your vehicle is supported on their website before you purchase.

The Carrfan CK-100 is the best car key programmer for home garages, thanks to its affordable price and guided key programming features, though it lacks the advanced functions you’ll find on other models.
