Immobilizer ?

[Doctor T]

In my handbook that came with the bike, it states that it is fitted with an immobilizer as standard. I've looked around the ignition lock and all i can see is a black box fitted to the cylinder. I have doubts i have an immobilizer fitted as my keys have no battery or chips in them. A VIN check states I've one fitted but if the keys have no internal battery or chips how does it work?. Was immobilizer's fitter to 2007 RT's?

I've one fitted but how does it work.

Cheers, once again David. Still can't see where the chip is in my keys. I suspect unlike car keys with chips in the BMW bike chip is molded into the plastic part of the key without a small tab you can open.

Plenty of car keys have moulded in transponders, the openable compartment is more indicative of central locking where the key has to actively transmit from a greater distance.

[Doctor T]

Is that why the new BMW M/C have a large key. Hence the central locking

[Graham88]

In part. The keyless ride feature is also an 'active transmit' so also requires a battery.
