BMW F 650 CS key quick facts
- BMW's US rider's manual for the F 650 CS, dated October 2003, says you receive two master keys and one spare key.
- The key number is printed on a plastic tag that comes with the keys.
- One key operates the ignition and steering lock, the fuel filler cap, the seat lock and the optional lockable stowage compartment.
- The steering lock engages only with the handlebars turned fully to the left, according to the manual.
- The optional topcase has its own key lock for the lid and a keyed retainer that holds the case on its mount.
- The manual has no EWS or immobilizer chapter, and the troubleshooting advice never mentions key recognition.

A single-cylinder BMW from before the chip key
The F 650 CS belongs to the same generation as the fuel-injected F 650 GS single, and like that bike it predates BMW's transponder keys. The key chapter in the rider's manual is half a page: two master keys, a spare, a key number on a plastic tag and a list of the locks the key fits. The ignition switch has four positions, ON, R, OFF and a parking light position, and the key can be withdrawn in all but ON.
Because there is no ring antenna and no chip, a hardware-store style copy of a good key will start the engine. That also means the bike relies entirely on its mechanical locks for security, so a worn ignition lock is worth fixing instead of living with.

What the CS key opens
The standard stowage compartment takes a softbag held by loops and a hook, so on many bikes there is nothing to lock there at all. Check which version you have before assuming a lock is missing.
- Ignition switch and steering lock on the top yoke; the manual says to lock the steering with the bars at full left lock
- Fuel filler cap, which BMW says should always be locked with the key after refueling
- Seat lock on the left side of the bike: turn the key, lift the seat at the rear and take it off
- Stowage compartment in the dummy tank when the optional lockable version is fitted
- Topcase, where fitted: one key position opens the lid latch and another releases the retaining hook so the case can be pulled off its mount
Things that go wrong with these locks
The seat has to come off for routine jobs, so the seat lock gets a lot of use. Watch for a tired key starting to bind there. The fuel cap sits exposed to road spray and benefits from the same attention as the ignition.
If a previous owner fitted a topcase from another bike, it may be on a different key from the ignition. That is easy to live with, but it is also something we can usually put right by matching the case lock to the bike key, so mention it when you call.
If every key to your F 650 CS is lost
Bring out your photo ID and the registration or title, and look for the plastic key tag in the document wallet. With the number, the key can be cut to the factory pattern. Without it, we work out the cut from the locks on the motorcycle. The finished key is checked in the ignition and steering lock, the fuel cap and the seat lock before we leave, and a second key cut at the same visit costs far less than starting again later.
No dealer order, tow or control unit work is involved on this model.
Where to find the key code
BMW's rider's manual says the key number for the F 650 CS is on the plastic tag supplied with the two master keys and the spare. Look in the original owner's document pouch. If the tag is gone, the key is made from the locks themselves.
What to have ready
Have this ready when you call or text
- Year, make and model of the bike
- Where the bike is parked
- Whether you have any working key, a broken key or a key code
- Photo ID and registration or title (we verify ownership before making a key)
BMW F 650 CS key FAQ
Does the BMW F 650 CS have an immobilizer?
Not from the factory. BMW's US rider's manual for the F 650 CS describes plain keys with a key number tag and contains no EWS section. An alarm or immobilizer added by an owner would be separate aftermarket equipment.
How many keys did the F 650 CS come with?
Three. BMW's manual lists two master keys and one spare key, along with a plastic tag showing the key number.
Is the topcase on the same key as the ignition?
The manual shows the topcase lid and its mounting retainer both working with a key, and the stowage compartment option shares the ignition key. Cases bought secondhand often arrive with their own key, so tell us what you have.
I have a key that works the seat but not the ignition. What does that mean?
On a bike with original locks one key should do both, so either a lock has been replaced at some point or the key is too worn for the ignition. Both are fixable at the bike once we see which it is.
