Promaster max keys

[darknezz19]

Full size Promaster has 1 key programmed, 7 keys disabled. Trying to add a brand new dealer key but fails to program. Tried to remove disabled keys over OBD with autel, but it failed. What are my options here?

I tired a dump of my own before you posted lion. Generated a keydiy Marelli bcm key, and then edited the 46 id to match dealer key. Then added it to the dump over the original working key with autel. Unfortunately didn't work. Was able to add the original working key back in though through obd. So there is no 8 key limit for bcm like I thought. The aftermarket key I tried was just bad, or who knows and just assumed hit a key limit for the BCM. Precoded another marelli aftermaket flip key and that one worked. Lock button wasn't working because sliding door was ajar from a theft attempt. What a wonderful job.

Still not sure why dealer key wouldn't go in. Either autel messes with the precode data in BCM, or dealer precoded it wrong.

Dealer key can ONLY add over OBD. If you can't -> Wrong precoding.

Give me a Fresh ID key, i'll add and give you back data for precode your key.

Just write back eeprom then start. Xhorse, keydiy not work very long for remote
