And while you're at the dealer order a SPARE key! Better to be safe than sorry. Trying to get a new key when you've lost or locked your only key inside the vehicle is a frustration you can remove now from you life without having to go through the experience.

You do NOT have to buy another expensive REMOTE key for back-up. There are non-remote keys that cost 1/3 to 1/2 the cost of the remote keys. Ask your local BMW dealership's Parts Dept how much the BMW keys below cost (give them the 11 digit BMW part nbr for #1, #3, and #5):

1. #1 is a metal blade spare key (approx $50)
2. #2 is a plastic "valet" key (approx $40) works the ignition & door only...will not open glove box
3. #5 is the remote key
