So i just bought a "new" 2005 545i from an independent dealer, and he ordered me a key from the dealer at his cost because the car only came with one key and i wanted a backup key.

The key arrived from BMW, but does anyone know how to program the key to the car?

i understand there's a certain way to do it, but i'm not sure if i have to take it to the dealer to do that or if i can do it myself.

thanks for any help with this,
brian

use old key to open the door, put new key in the ignition, wait for a few seconds. Start the car, new key is programmed. Test by closing the door with the new key.

It's done the same way for the blade key as well? (I know this is the way to do it for key fobs)

it worked perfectly! thanks so much.

but i want to mention, i put the key in, left it for a few seconds, and then took it out and locked the door to test, it did lock the door manually, but the buttons were not working.

so i did it again, but this time i started the car with new key in ignition (there was a slight delay before it turned over) - and then it started the car, left it run, shut off. after that the buttons to lock and unlock all worked correctly.

thx again!
