One user feedback: have Xhorse vvdi2 and vvdi mb. And very happy with that. And done a lot of keys. but many customers ask for other keys also mostly vag and bmw. Looking for good universal remote that can be used in most of the vags and also bmw with key blade.
Xhorse has universal remote/blade systems. But you will still need to learn them to the vehicle.
I use https://www.obdii365.com/producttags/xhorse-remote.html they are a very reputable company with some of the best prices, I will say this. Xhorse VVDI2 is a must have tool. However the universal flip key with remote is touch and go. Its 99 percent success with transponder programming or cloning with an xhorse superchip. The remote cloning I have little to no success with. Remote generating and programming I would say I have a 60 percent success rate. Very vehicle specific, and much better on pre 2015 vehicles for remotes. All this being said. I do love there product and pricing. I just wouldnt put all my eggs in one basket. They are great go to when you have many options for the economical customer.
AS I said you can do a lot with transonder. ID48 Cloning cost points similar to tokens. It works very well on vw and audi. The xt27 superchip is amazing it can be programmed many times over and over and continue to work. I have often just used one for testing probably programmed over one hundred times. If you buy 100 you get a big discount. You can use them on so many different vehicles. Then you can purchase cheap shell transponder keys and just generate or clone yourself. Now if you are all key lost, You will be reading the immo dump and either generating your own new key file or easier grab one and use your VVDI2 to clone one of the already made keys. The program to do that is in the transponder area of the tool software. If you are trying to do immo 5 and up MQB key I don’t recommend using other keys and yes if that means purchasing some for stock then so be it. Dont be afraid to spend money on tools and inventory. You will make it back little by little and then use half your profit to buy more stock so soon you won’t have to order and wait for overseas shipping. As far as your universal key question. Look at xhorse 3 and 4 button super remote item#5261. It has a super chip inside it already. So you can literally program or clone like 15 different chip types (think of how many cars you can do with that one remote, only thing missing is the blade). Buy like 20 of this remote and then buy many different key blade inserts. That will get you up and running, to hopefully purchase more product to have on hand.
Alright, here I attach one image of Xhorse universal remote:
