Identifying the Release Mechanism
Most BMW key fobs have a small release button or slot, usually located near the key ring. This button or slot releases the emergency key blade, which often doubles as a lever to open the key fob casing. Some newer models might have a slightly different mechanism, so consulting your owner’s manual is always a good idea.
