Mercedes W210 / Add key / All keys lost / Autel IM508 / Xhorse Key Tool Plus Pad

I decided to write the key with Autel IM 508, but the immo date was calculated and the password could not calculate, decided to try to calculate Xhorse Key Tool Plus Pad, it calculated the password but did not understand how to calculate the immo date, I took the password that was calculated and made a key faile with Autel, after making a key faile and wrote it into the key for W210 you need to activate the key with a programmer. After all the work done, I put the lock on the car, inserted the key and the steering wheel latch worked immediately, the key is recognized. After 5 minutes and the buttons on the key worked.
