I've got keyless, but can't really see the point - if you need to lock/unlock panniers, lift the seat, or take the Satnav off, you still have to use the "manual" key attached to the keyless one. The plastic transponder key breaks easily, as I found out. Ordered a plain old-fashioned metal key through BMW (not expensive) which I keep on a spare keyring with the broken transponder key in my trouser pocket and to give to a mate to carry as back-up when on trips, and I can keep the keyless one tucked safely away in my jacket. SORTED.
