868 MHz Replacement Remote Key

This three-button remote key operates at 868 MHz and uses a PCF7945 transponder chip. It is a non-OEM replacement fob intended for adding a spare or new key to compatible BMW models. The unit includes the circuit board, battery and transponder chip inside a black plastic and metal housing. Professional locksmith programming and key blade cutting are required before the remote will start the vehicle.

Build and Daily Handling

The fob measures 6.8 by 3.6 by 1.4 centimetres and weighs very little, so it fits easily on a standard key ring. Three tactile buttons replicate the original lock, unlock and trunk functions and are rated for comfortable daily pressing. An insert-style key blade is supplied uncut; a locksmith must mill it to match the vehicle’s door and ignition cylinders. The 868 MHz frequency and included electronics are ready for programming once the blade is prepared.

PCF7945 Chip Compatibility

The single specification that decides fitment is the PCF7945 transponder chip paired with the 868 MHz operating frequency. Only vehicles listed in the fitment data — covering specific 1, 3, 5, 6, 7 Series, X5, X6 and Z4 chassis codes from 2002 to 2013 — use this exact chip and frequency combination. Buyers whose vehicles require a different transponder type or frequency cannot use this remote, even if the case looks identical.
