BMW R 12 nineT, R 12 and R 12 G/S Key Replacement

Quick answerThe R 12 family replaced the keyed R nineT with a Keyless Ride setup: the bike is supplied with one radio-operated key and one spare key, and the ignition is a button. The key blade is still needed, because the steering lock and the fuel filler cap are locked and unlocked by hand. If the fob is lost, the spare key starts the bike, but only after the seat has been removed to reach the ring antenna underneath.

BMW R 12 nineT, R 12 and R 12 G/S key quick facts

BMW's R 12 nineT rider's manual says the motorcycle is supplied with one radio-operated key and one spare key.
On the R 12 nineT the ignition and the anti-theft alarm, if fitted, work with the radio-operated key, while the steering lock and fuel filler cap are locked and unlocked manually.
The steering lock is a separate lock: the bars go fully left, the vehicle key is pushed in and turned.
To start with the spare key or a fob with an empty battery, the manual has you remove the seat and insert the key into the ring aerial under it, then start within 30 seconds.
If the fob stays out of range, about 3 feet (1 meter), the ignition switches off after about 90 seconds to protect the battery.

What changed from the R nineT

The original R nineT had an ignition lock you put a key in, two ignition keys and a little third key for the passenger seat. The R 12 nineT, the R 12 cruiser and the R 12 G/S dropped the ignition lock for a button and a fob. BMW still calls the anti-theft side of it EWS, and the manual has an electronic immobilizer section, but day to day you ride with the fob in a pocket.

What did not go away is the metal key. This is a simpler Keyless Ride than the one on the big GS: the system does not lock the steering or release the fuel cap for you. Both are done with the key blade, so the blade on a replacement fob has to be cut correctly or you will not be able to refuel.

Steering lock, fuel cap and seat

Three places on the R 12 need attention when keys are replaced.

Steering lock: a separate key lock used with the handlebars turned all the way left; the key is pushed in and turned, and BMW warns you to remove it before riding off
Fuel filler cap: opened with the key under a protective cap; you press the cap down to close it and take the key out
Seat on the R 12 nineT: not a key lock at all; the manual shows a cover being removed and the on-board Torx wrench and extension used to release the seat
Ring aerial for the spare key: under that seat

Lost fob on the road

BMW's guidance is to carry the fob on you and to have the spare key as the fallback. The spare is a real backup, but it is not a ten-second fix. On the R 12 nineT, and on the R 12 G/S, you have to take the seat off, place the spare key or the dead fob into the opening of the ring aerial, wait for the key to be recognized, start the engine within 30 seconds and refit the seat.

That makes two habits worthwhile. Keep the spare key somewhere on you and not at home, and know where the bike's Torx wrench lives before you need it in a parking lot. The R 12 nineT manual says the fob battery has to be replaced when the fob's LED shows red, and doing that early avoids the whole exercise.

Both keys gone

With no fob and no spare, the R 12 cannot authorize a start, and the steering lock and fuel cap stay shut. BMW's manual says spare keys are obtained through an authorized retailer, who is obliged to check that the application is legitimate, and that a lost key can be disabled.

This is a recent platform, and what can be done at the roadside for it is still narrower than for older BMWs. Call with the exact model and year and we will tell you straight whether we can program a fob for it on site or whether the dealer is the right route. Either way we can cut the key blade, free a steering lock or fuel cap, and look after the mechanical locks at the bike. Have photo ID and the registration or title ready.

Where to find the key code

The R 12 manuals do not refer to a key code tag. Replacement keys are handled against the VIN with proof of ownership.

BMW R 12 nineT, R 12 and R 12 G/S key FAQ

Does the R 12 nineT have a normal ignition key?

No. It uses Keyless Ride with a button, and is supplied with one radio-operated key and one spare key. You still need the key blade for the steering lock and the fuel filler cap.

Where do I hold the spare key to start an R 12 nineT?

In the ring aerial under the seat. The manual has you remove the seat, insert the spare key or the folded fob with the empty battery into the opening, and start the engine within 30 seconds of it being recognized.

Will the fob unlock the fuel cap on my R 12?

No. BMW's manual says the steering lock and fuel filler cap are locked and unlocked manually, with the key.

Is the R 12 key the same as the older R nineT key?

No. The 2014 to 2023 R nineT has a keyed ignition with a transponder key. The R 12 family uses a radio-operated key and a start button.
