Diagnostic And Service Functions

The X100 Pad2 has the same 8 service functions found on the X100 Pad. Its main improvement from a diagnostic standpoint is the inclusion of 4-system diagnosis. This means you can read codes from the ABS, SRS, and transmissions systems, not just the engine.

Wider Compatibility

The biggest difference between the X100 Pad2 and the X100 Pad above is its range of compatibility. It includes a wider array of adapters, and its IMMO and service functions are supported on more manufacturers. This includes newer models, like the C-class and E-class Mercedes left behind by other versions of the device.

FICBOX 4D Chip Keymaker can program new keys for Toyota and Lexus vehicles in about 20 seconds.

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 disrupting the car’s anti-theft protocols.

Select Compatibility

Now here’s the rub: you can’t use the FICBOX Chip Keymaker on any vehicle. It will only work with Toyota and Lexus vehicles that use the 4D chip—basically those that were made from 1996-2008.

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.

Pros

  • Add a key in as little as 20 seconds
  • Won’t disrupt vehicle’s anti-theft system
  • Can make new keys even if you’ve lost the master
  • Very affordable
  • Lightweight and compact design

Cons

  • Limited compatibility (Toyota/Lexus with 4D chip)
  • No IMMO or ECU programming functions

Verdict

The FICBOX 4D Chip Keymaker is the most affordable ways to make new keys for Toyota and Lexus vehicles.

The Autel MP808K can effectively program key fobs for a wide range of vehicles. It also supports ECU coding. Having said that, though, it’s more a diagnostic scanner with keymaking abilities than it is a dedicated key programmer. Its IMMO functionality is a bit limited, and on some vehicles more than others.

OE-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. While you won’t get all of these on all supported manufacturers, it’s still one of the best repair tools on the market.

  • Programs key fobs for most vehicles
  • 23 service functions
  • All 10 modes of OBD2 supported
  • Diagnoses all systems
  • Supports bi-directional control

Comprehensive OE-Level Diagnostics

Along with all 10 modes of OBD2, the IM608 can read trouble codes from most electronic systems. You can diagnose systems like the airbags or anti-lock brakes quickly and easily. In addition, auto-VIN and Auto Scan functions are an efficient way to diagnose any vehicle.

Robust Special Functions

Advanced maintenance services of the MaxilM IM608 include oil reset, battery and TPMS relearn, and maintenance of the EPB, SAS, and DPF systems. These functions are available for most vehicles, too, unlike most hand-held scanners which are limited by manufacturer.

Intuitive Design

The 10.1” touchscreen on the Autel IM608 is larger than you’ll find on most diagnostic scanners. This gives you more room to view diagnostic data and a clearer picture of your vehicle’s health.

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.
