Most recent BMWs use a smart fob and a start/stop button. With the fob in a pocket or bag, many of them unlock as soon as you touch the door handle and lock again when you walk away; on others you press the buttons on the fob. Either way the engine starts with the button, not a turn of a key, and the car has to recognize the fob before it will run.
Inside every BMW fob is an emergency blade. Find the small release on the fob, slide the blade out, and it opens the driver’s door when the fob battery dies. On many BMWs the lock cylinder hides behind a little cover at the end of the driver’s handle, so it’s easy to miss. Many models also have a marked spot — on the steering column or in the center console, depending on the model — where a fob with a dead battery can be held so the car still reads it. Your owner’s manual shows where yours is.
Older BMWs work differently. Many 3 Series and 5 Series from the 2000s use a fob you push into a slot in the dash before pressing start, and older ones still use a turn key. BMW and MINI blades are laser-cut — a groove milled into the blade instead of notches on its edge — and we cut them at the car from your key or from the key code.
MINI is owned by BMW, and it shows in the keys. Many MINI Coopers from about 2007 to the mid-2010s use a rounded fob that pushes into a slot beside the steering wheel; many newer Coopers, Countrymans and Clubmans use a smart key that stays in your pocket while you flip the start switch.
All that variety is why we ask for the VIN before anything else: it tells us which key your BMW takes and how it programs. We have the equipment for newer BMWs as well as older ones. Once in a while a specific model and year turns out to be a dealer-only job, and when that happens the dispatcher tells you on the phone, before anyone drives out.
