Bmw 3 Series Cas3+ Istap all keys lost

full instructions on how to program a key to the car , I’ll be posting a video of how we get the dme out and wiring it to the G-box to pull the isn code.

Thanks for the great video! For someone trying to get into the business, this is amazing.

Our pleasure!

get something like ACDP that reads and makes key by eeprom dump. zero downgrades. best investment i've ever made. no soldering. no more fixing fuck ups from programmers that require a reflash to access key file.

[@derekkchung]

I was told that Autel KM100 can do CAS3+ all-key-lost. Have you tried that?

[@mohamedbashire5869]

Thank you very much ❤

ISN code is needed to decrypt CAS date to make a key. It actually takes about 15 min to read ISN code from DME directly on the bech.

Good evening my brother, I really like your work from my country. I have a 2012 BMW X6 E71. I would like to know is this the same procedure to follow to reprogram the remote control lock? The key starts the vehicle but it no longer locks the ports. I changed the kidney battery. Can you direct me please?

[@jonathanromero8639]

Question bro, if I have a working key can i get the ISN from the key or how would i go about programming a blank key with 1 working key. Also, it would be done on an otofixIM1 programmer which seems very similar to the one in your video. Any suggestions would be greatly appreciated, new at this but have enough knowledge around cars. Haha

[@tomking3942]

If you get the car to turn on then back out to read isn will that work? The 64 times seems time consuming. The dme read only requires us to get the car on right?

[@KeyMaker-22]

Well yes if you have a key and you can get it on it’ll let you read the isn code , but in this case all keys were lost , I usually read the dme for the ISN code but for these 3 series with cas3 istap it’s a bit of work to disassemble the all the plastic to get to the dme so I just try this first . It’s not to time consuming

[@myroad5469]

Hello plz So we must not have isn code to do all Key Lost on cas3 + istap ??? Thank you for your Replay 🙏

[@KeyMaker-22]

Yes you do need it but sometimes when you do the 64 starts it’ll work like in this case , always have your G-box ready in case it doesn’t work

Car needed to be running 15min at the end? I have add key with cas istap first time. I wont to do on bench becouse people says its safer

[@KeyMaker-22]

I syne the dme 20 times then let it run just to be on the safe side .

[@tomconner5067]

Deadlocked BMW’s will disconnect the lock cylinder from the latch assembly on the drivers door, even if you’re in the car you still can’t open the door. In order to gain entry in this situation, simply air wedge the passenger side door and double pull the inner door handle, the alarm will sound, just pop the hood and attach a battery charger to the jumper 12v + terminal, and 12v negative/ground. And by that time the car will quit carrying on. I might add you should open every door when you first gain entry to minimize the alarm noise duration. Hatch too, use the glow in the dark escape handle

[@KeyMaker-22]

only time Iv ever had an issue was on 2006-2007 Range Rover with an ews system which was locked and we had a lot of people come to try to unlock it I made a key for the door and everything but nuthin we ended up busting the window .

[@Juppie902]

I did a similar range rover I broke the window but alarm didn't sound until I put a key without a chip in it to the IG switch, the thing is the inner lock mechanism broke so you can't open the car with the key and inner door handles don't work when locked and Remote didn't work.

[@robwanhella6860]

Do you have the ISN from the DME

[@johnholding107]

Did you watch the video?

[@robwanhella6860]

@@johnholding107 yes i did and was also watching when i installed it in the vehicle, but it went in quickly no waiting or anything, but yes it did work well for me Thank You

[@KeyMaker-22]

In this situation I just did the 64 try’s and it worked , but usually we have to pull the dme .

13+ VOLT POWER SUPPLY?

[@KeyMaker-22]

I used to , but as long as it’s stable at 11-12 volts iv never had an issue

[@car-key-programming]

Not true what you said about mobile hotspot. I've been using my phones hotspot for years and using it at the same time and never had an issue. Not saying i will never have a problem but so far no. But also depends on who your service provider is.

[@KeyMaker-22]

Be careful with that iv seen many cas3 get damaged , better same then sorry.

[@car-key-programming]

@KeyMaker-22 If it gets its data damaged, all I have to do is pull it out and renew it, then program back in the car. No big deal. Just sucks for the customer as he has to wait longer.

[@convertathletics4564]

Terrible. Istap is the firmware encryption and should always be done on bench. Funny how autel labels this process as an upgrade. Doing these OBD with any tool is frikking cowboy. I wonder how many cas units and dme this guy has bricked.

[@KeyMaker-22]

Actually if the battery voltage is steady and if you have solid internet you won’t have a problem , iv done a few hundred same way never had an issue. In my career I bricked 1 because I connected jumper cables to it to try to keep it at 13v and somehow it failed to downgrade but I also have an autohex which helped fix the flash that I erased . People get told a lot of things by guys that learned from an older generation that looked at European cars as a dangerous/risky thing but I’ assure you like everything in the word people learn easier and better ways of doing things by going out researching and trying . Hope you enjoy the videos .

[@Eurosmithpro]

Ok sir. Im not getting into a pissing match w you. All I have to say is: Any tech that has actually done 100 bmws will know that this statement is total bs.
