BMW F 750 GS, F 850 GS and F 800 GS Key Replacement

Quick answerBMW's middleweight GS twins use the EWS immobilizer, so a new key needs programming as well as cutting. The F 750 GS and F 850 GS come with either a keyed ignition and two keys, or optional Keyless Ride with a fob and an emergency key. One key works the ignition, fuel filler cap and seat lock, and Vario case locks can be matched to it.

The key and immobilizer by generation

The F 800 family manual describes EWS the same way as BMW's bigger bikes: the engine can only be started with keys that belong to the vehicle, signals pass through a ring antenna in the ignition lock, and a dealer can bar an individual key if it goes missing. That wording is from the F 800 S manual. The F 800 GS, F 700 GS and twin-cylinder F 650 GS share that platform, so check your rider's manual for your exact model.

The F 750 GS and F 850 GS keep EWS and add a choice. The standard bike has a keyed ignition. With the Keyless Ride option the manual refers to a remote-control ignition lock, and you get one radio-operated key and one emergency key.

What the dash tells you

When the immobilizer is active, the general warning light comes on yellow with the EWS warning symbol. BMW's manual gives the cause as a key that is not authorized, or disrupted communication between the key and the engine electronics. The listed remedies are to remove other keys from the ring, use the spare key, and have a defective key replaced.

Keyless Ride bikes have two more messages. One warns that the radio-operated key is out of range, with the advice to check or replace its battery and carry on with the reserve key. The other warns that the fob battery has lost much of its capacity. The manual adds that if the warning appears while riding you can continue, because the engine will not switch off.

Locks and luggage on the same key

The F 850 GS manual says the ignition switch, fuel filler cap lock and seat lock are all operated with the same key. Vario cases and top cases have their own lock cylinders, and BMW dealers sell a key-matching kit for F 750 GS and F 850 GS Vario luggage that sets the cylinder to the cut of an existing key, either the ignition key or a key already used on the luggage. On a used bike, expect either arrangement.

With Keyless Ride the fob has a fold-out key blade, and the seat lock, top case and cases are still worked by hand.

Trail and travel problems

Flat fob battery far from home: on the F 850 GS the manual says to remove the seat and insert the folded fob or the emergency key into the ring antenna under it. The fob battery is a CR 2032.
Bent or snapped key after a drop: a keyed bike still needs the chip from that key or a newly programmed one, so keep every piece.
Single key on a used adventure bike: get a second key made while the first works, before a trip rather than during one.
No keys at all: a dealer orders against the VIN after checking ownership. We come to the bike, and we ask for photo ID and the registration or title.

BMW F 750 GS, F 850 GS and F 800 GS key FAQ

Where is the emergency key antenna on an F 850 GS?

Under the seat. BMW's manual says to remove the seat and insert the emergency key or the folded fob with a flat battery into the ring antenna there.

Does my F 750 GS have Keyless Ride?

Only if it was ordered with that option. A key slot at the steering head means a keyed EWS bike, and a button means Keyless Ride.

Can my Vario cases be put on the ignition key?

Yes. BMW's key-matching lock cylinder kit for F 750 GS and F 850 GS Vario cases is set up to an existing key, so the luggage and ignition can share one.

Does the F 800 GS have a chip key?

The F 800 family manual describes the EWS immobilizer with a ring antenna in the ignition lock, so plan on a programmed transponder key rather than a plain cut key.
