Today I bring you the evaluation of OBDSTAR X300 PRO4 and Xtool X100 PAD3.

Generally, they have similar price of less than 1,000$, and they can do key programming for 80-85% budget cars. (Not good for Benz, BMW...)You may need it after you've worked on initial programming with like Kess for a while and customers start to ask key programming for you. 

The Xtool has free updates for 2 years, while the OBDSTAR is one year. 

For others they are similar, EEPROM, IMMO... menus are separate on PRO4. 

RU cars

Can they program Renault Lada Vesta? These platforms are based on continental blocks. The two scanners basically read them for diagnosis, but Xtool PAD3 sometimes cannot make my Lada when I lost all keys, although when adding it makes them. X300 PRO4 never has this problem. It’s able to read FLASH and add keys, but it happens that it cannot read it when all keys are lost. 

US cars

I have a Grand Cherokee 2006, but I couldn't read it on PRO4, and the pin code is trouble. I have done more than ten Cherokee and never had any questions about this.

Toyota smart key

Both fine, even Camry 2021 adds right. They all have simulators for all keys lost, read data and write it to the simulator and the car comes. But, for Aqua 2014, the Xtool reads EEPROM without problems, but I couldn't write down the PH94 type.

Benz

If you have to do Mercedes-Benz, the Xtool doesn’t know how to do them fully but can add key for young Benz if you get a KC501 Key Programmer. Xtool goes further, and they add more professional cars. That is what I don’t smell on this OBDSTAR.

Summary

Better to take another device because it'll be more professional, Xhorse, MB tools...If I have the PRO4, I would never learn BMW and Mercedes, and never restore keys fully to Toyota smart key.

Of course, there are more advantages for this Xtool because diagnosis is strong, 2 years warranty, 2 years free updates. If you want to make a Mercedes or BMW with budget, you can still consider Xtool.

More tools you get, more confident you will be.
