Key wont' turn bmw 645ci, code is good and programmed

[labusas]

Hello, I have a dillemaI have a lost all keys. Car is 2004 bmw 645ci with cas3.
Read cas and retrieved a code. Droped last digit from code and found cuts.
Key is cut and transponder programmed OK.
Key turns in the door but ignition WILL NOT!
Why?
correctly programmed chip is detected by "remove key" icon on the display.


Is this because stearing lock is "locked" or some difference in door versus ignition cuts in the key?


I would appreciate your input since the car is still stranded.

it doesnt mean if it opens the door it should open ignition , there is difference in door and ignition as far as i know , iginition uses 1 extra cut depth i think
correct me if i m wrong

[labusas]

Yes but the key was cut from code 0598 which was retrieved from CAS directly.

Can anyone confirm cuts. I used instacode 2008. It didn't list 645ci though.
I use miracle A5 and selected silca hu92

i dont have instacode to confirm it , but the bmw iginition works with just a blade even without transponder , so the programming is not the issue here , definitely its the cuts , maybe the blade is faulty with wrong measurements , try another blade or maybe the ignition is jammed

try to unlock steering if lock
i m not sure about the extra cut in ignition
key code give u id get 8 cuts is good
not sure
what are u using to read cas module

Good chance the ignition had been replaced to a random key.
I am not sure if a 2 in 1 pick will work on the ignition.
I have been able to over lift these though in the past to get them to turn.

Cuts should be 24323424

have done same a few week ago (effi work great xD) and ignition have 8 cuts. if key dont cut perfectly dont work. when you done a little force in ingnition, turn?

[labusas]

Thanks all for ideas.
Fallen, what do you mean by over lifting? And Yes, those are the cuts I have.
I still think its something to do with car being locked via a remote. Now I made only a transponder - no remote, hence can't unlock steering which jams ignition. Maybe transponder ONLY key needs to be initialized by ignition ON first? So, if I had a remote key it wouldn't be a problem. Just an idea. I checked with a calliper and cuts are correct.

sorry , my mistake ,

should be ok

[labusas]

Thanks for the pic. It looks like the tip is cut wrong on mine. Yours is wider tapered to the tip past cut 1.
Maybe that's the ticket!

[topclef]

do you mean N?8 ? maybe , i use Viper , i never had problem .

[labusas]

I widened the tip and no go

[keygargoil]

It is probably the calibration I know a few people who struggle cutting hu92 keys on a5 the keys just about work the door and won't turn the ignition I use viper and never had any problems or it could be a different ignition lock 2 in 1 works on the ignition

Overlift means lift all the wafers up with a blank and apply tension so they stay up.
Gently release the tension and you will hear the wafers click back into place.
Do it right and it will turn.

Make sure the key is going all the way in too.
