Autel vehicle coverage stops at 2020 for this model Cadillac. But the coverage is not 100% correct.  A CANFD adapter is required no matter what.

Obdstar does this right from the tool.

Test report:

2021 Cadillac Escalade knife smart key all keys lost is done by obdstar keymaster dp plus. Autel km100 generated a key for it just fine.

This immo requires a pin code from a 3rd party, this is the ONLY tool that does it all from the scan tool automatically. it took about 10 minutes for it to get the code. then only a few minutes to actually program the key.
You also have to use the can fd adapter.

What more advantages does obdstar X300 DP Plus have? Let’s read one user’s feedback:


I bought it because it’s the 1st tool out that can do the 2021 GM, also 2021 Dodge.

Clone gm bcm

Has toyota akl bypass

Ford akl active alarm bypass cable.

You can buy the full adapter set and you get free motorcycle immo key learning. also PWC into.

Also has odometer change. I already have the odometer table from them and it’s got good coverage and works good.


I used it today for the first time, 2007 ford freestyle AKL. 2010 Pontiac g6 AKL, 2018 Hyundai sonata AKL proximity key.

Right now I’m doing a 2018 Malibu proximity keys so far it’s done them all, and it was pretty quick pulling pins. both gm and Hyundai.

so far it’s working out pretty good.


Why I go with the obdstar X300 DP Plus / Keymaster DP Plus over the code cannibal?

Because with the obdstar one you can buy the MOTO IMMO adapter set and it comes with ford AKL active alarm bypass cable. Toyota can cable. and also it gives u the motorcycle and PWC key programming license. can’t get that with code cannibal.

and also the keymaster dp plus also has odometer capabilities. and I already have the obdstar odomaster and it has good coverage. I’ve been happy with it.



4. Xtool [Server is down]

Even 500euro Xtool D7D8D9D9 Pro series can do CAN FD. Xtool D7 can do it, but it does not have built-in CAN FD, you need a CAN FD adapter.

xtool is stable on this and very fast.

x100 tablets with new updates and CanFd 100% no security code like old models.

5. Buy 24-digit security code from 3rd party, then program key with OBD programmers.

Contact @Ameer Hasan on facebook. He will provide BCM rolling code in 5-10min.



Hope it helps!
