To reprogram a BMW Z3 key switch after replacement, you will typically need to use a specialized diagnostic tool or follow the vehicle's manual if it provides specific instructions. Generally, the process involves turning the ignition on and off in a specific sequence while pressing the key fob buttons to sync it with the car's electronic system. If you are unsure or the procedure is not straightforward, consulting a professional locksmith or a BMW dealer is recommended for assistance.

When you change the ignition switch, you often do not need a new key, as the existing key can still work with the new switch if it is compatible. However, if the ignition switch is part of a more comprehensive security system or if it is designed to work with a different key pattern, you may need a new key or to reprogram the existing key. It’s best to consult your vehicle's manual or a professional to confirm the specifics for your car model.
