  • Amazing find; easy to use
Too good to not write a review. I had to share positive experience. I purchased this after it was recommended elsewhere to help program new key fobs for our 2019 Acura MDX. I was adding a remote start module and the new fobs needed to be programmed and immobilizer reconfigured. This controller was able to do all of it. Quickly. Only downside: initial activation was a little convoluted. You need to enter the registration information from the manual into the phone app after you download and create a login. After setup is complete, though, the unit is super easy. ... show more

  • DOES DO KEYS!
Bought this on the chance the info was actually correct and that it could enroll chip keys for my 2025 Nissan Rogue Select. IT DOES! The setup, registration, software downloads were simple enough and work flawlessly on my iPhone. The erase/enroll steps for the immobilizer were clear and easy to follow (be sure to write down the passwords and any other numbers it captures, so you have them for the steps immediately following). Calls around for keys/programming ran from $125 to $250 PER KEY TO CUT AND PROGRAM! I bought four chip keys (be sure to match the FCC ID and Chip number to your original key), cut them myself, and all four enrolled in the immobilizer flawlessly, FIRST TIME! I can’t speak for everyone or every vehicle, but I can say that just about everything else for the 2015 Nissan Rogue Select “J”-VIN has been a challenge to match parts and harnesses for, but this little baby made keys a no-brainer! ... show more

  • Up there with autel and snap on
This thing is amazing ! It can do it all from check engine lights all the way to actually coding the PCM on a vehicle . And every thing in-between. For the price it is well worth it . It also works on almost every vehicle imaginable . Connects quickly to your phone or tablet and then to the car . It also comes with a year of free updates . I have messed with it for months and still have yet to see everything it can do . Highly recommended . And I am not paid for this review . Thanks ... show more

  • Doesn't work as advertised.
I too considered the negative reviews and decided to try anyway. I emailed ThinkCar and got confirmation that I could do a 2008 Prius ABS brake bleed and linear offset relearn for our ABS actuator replacement project (yes, the $1200 part, or the $2700 repair at your local shop). It can be done. The mechanial part is actually not hard, just tedious and time consuming. It's the post repair configuration that gets you. I noted in the product FAQ's that functions were not as "robust" on IOS, so I purchased an Android tablet. Software would not install, said incompatible. First flag. Installed software manually on the tablet no issues. Initialized the software for Toyota and successfully registered and connected to car. Proceeded to run the ABS brake bleed but it would not finish successfully, crashing at various points or finishing "unsuccessful". Four hours of retrying and searching for answers, no luck. No online support, email or phone only during work hours m-f. Not taking a day off to get the runaround as described in other negative reviews. We then proceeded to use the mini vci cable and cloned tech stream software also purchased off Amazon. (Which involved building a windows 7 pc for compatibility, and downloading an ancient copy of tech stream from a forum because the software included in the Amazon product was bogus.) Which, believe it or not, actually worked. There are other required functions in order to actually complete the job: resets, clear the various DTC's due to the system being dissembled, and a final reset to clear the brake, abs and vsc dash lights, which I'm not sure the ThinkDiag could accomplish, never made it that far. This seems like a great product for DIY work. Affordable at $135, a great advantage over other products - which there appear to be none. I spent several hours and contacted several vendors trying to find a diagnostic scanner to do this work and it appears there are none, save the several thousand dollar commerical products, or possibly the Harbor Freight scanner at $900. Sorry folks, very enticing but not ready for prime time. ... show more
