    Damaged keyless ignition switch

    Some low life today attempted to steal my bike, luckily a work colleague noticed what was going on and the thief fled, but not before he broke my steering lock casing 🤬. My question is has anyone used a second hand switch and stripped down to swop the electrical box, or am a going to have to bite the bullet and get a new one then take to dealer to have it paired ?   😡😡🤬🤬🤬

    As far as I understand, the pairing is not performed by the switch, it's performed and stored in the ECU. Hence, the switch is just a Dummy. The antenna for keyless is to be found under the seat, the unit that is also used as an emergency start if your FOB battery is dead.

    Cheking the repair DVD the DVD says that when changing the switch control unit, it needs to be coded, but if changing the switch only, the  electronics will not be changed. But there is no pictures of details to indicate wether it's even possible to separate the switch from the controll unit

    Probably a good idea to get this confirmed by the dealer.

    i was told it is that circular area right next to the battery on the clutch side of the bike

    I've only owned 2 bmw so far, the antenna is never on the switch itself but the location varies. Bummer about the bike, hope your insurance covers it.

    Thanks Newguy, Put the post out there to get confirmation regarding the switch and if requiring trip to dealer to pair which has been answered. Havenít got my insurance involved because the excess is prob more than the switch costs, will keep looking for a used switch on the sale sites, bike still runs fine just no steering lock which are useless anyway , back to disc lock, ride safe all 😊👍
