A K bike without a transponder

People often assume that any BMW built after 2000 has EWS. The K 1200 RS does not. BMW introduced the transponder key on its motorcycles with the newer CAN-bus models, starting with the R 1200 GS and then the K 1200 S that replaced this bike. On the RS, BMW's parts catalog shows what you would expect of an older design: a metal key blank, keys that the dealer could order already cut from the key code, and lock cylinders. The rider's manual for the K 1200 GT built on the RS likewise describes plain keys with a key number tag and no immobilizer.

BMW's 2004 maintenance booklet for the RS points the same way. Its chart for an engine that will not start lists the ignition key position, the kill switch, the side stand and the clutch, and says nothing about a key being recognized.

The light-up key head

Some K 1200 RS keys have a bulky head with a push button and a tiny bulb. It is easy to mistake for a remote or a chip, but it is a flashlight for finding the keyhole at night. BMW listed the head, its battery and its bulb as separate spare parts. If the light has stopped working, the key still does its job. If the head has cracked and the blade is loose in it, the blade can be copied onto a new key.

Locks on the RS and what is behind them

The seat lock deserves respect on this model. BMW's maintenance booklet puts the fuses, the battery access and the toolkit compartment under the seat, so a seat that will not unlock turns a blown fuse into a stranded bike.

Ignition switch with the steering lock in one housing on the fork bridge
Fuel tank lock in the filler cap
Dual seat lock, which the maintenance booklet has you close and lock after working under the seat
Cases, if fitted: not part of the lock listing for the bike itself, so tell us whether yours are on the ignition key

Getting a new key made

We start with proof of ownership: photo ID and the registration or title. If you have the key number from the original key tag or dealer paperwork, the key can be cut to that code. If you do not, the cut is worked out from the locks on the bike. Either way the key is tested in the ignition, the steering lock, the fuel tank lock and the seat lock on site.

Lock cylinders for this family could be supplied matched to a code, so a worn or damaged lock can usually be set up to the existing key instead of leaving you with two keys.

Where to find the key code

BMW's parts listing for the K 1200 RS shows ignition keys and lock cylinders that could be ordered by key code, so a code existed for every bike. Look for it on a tag or label in the original document wallet or on old dealer invoices. Without it, the key is made from the locks.

BMW K 1200 RS key FAQ

Does a BMW K 1200 RS have an EWS immobilizer?

No. BMW's parts listing for the K 1200 RS shows a plain key blank and keys cut to code, with no ring antenna or immobilizer parts. EWS arrived on the K 1200 S that followed it.

The button and light on my K 1200 RS key stopped working. Will the bike still start?

Yes. The illuminated head is only a small light powered by its own battery. The cut blade is what operates the locks.

Can the fuel cap and seat be kept on the same key if my ignition lock is replaced?

Usually, yes. The replacement lock can be set up to the bike's existing key so one key continues to work the ignition, fuel tank lock and seat.

Is the K 1200 RS key the same as a K 1200 S key?

No. The K 1200 S is a later design with a transponder key and EWS. The RS uses a cut key with no electronics involved in starting.
