> The oilhead boxers, from the R 1100 models of the 1990s through the R 1150 GS, R, RT and the R 1100 S, were built before BMW fitted the EWS immobilizer to its motorcycles. Their rider's manuals describe two master keys, one spare key and a key number tag, with no immobilizer section. A lost key is a cut-at-the-bike job with no programming.

**BMW R 1100 and R 1150 oilhead boxers key quick facts**

- BMW's 2002 US rider's manual for the R 1150 GS and GS Adventure lists two master keys and one spare key, with the key number on an accompanying plastic tag.

- The 2000 US manual for the R 1100 S says a small self-adhesive label showing the key number is supplied with the keys.
- On the R 1150 RT the key also fits the storage compartment and the System cases, as well as the ignition, tank filler cap and dual seat lock.
- None of these manuals contains an EWS or electronic immobilizer section.

## BMW R 1100 and R 1150 oilhead boxers key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| 2000-2005 | R 1150 GS, R 1150 GS Adventure, R 1150 R, R 1150 RT, R 850 RT | mechanical cut key | no | Two master keys and one spare key, key number on a plastic tag, per the 2002 manuals. |
| 1999-2005 | R 1100 S | mechanical cut key | no | Two master keys and one spare key. Key number on a small self-adhesive label per the 2000 US manual. |
| About 1994-2001 | R 1100 GS, R 1100 R, R 1100 RS, R 1100 RT and other earlier oilheads | mechanical cut key | no | Same pre-EWS generation. We confirm the details for your exact model when you call. |
| From 2004 | R 1200 GS and the boxers that followed | transponder key (EWS) | yes | Not an oilhead. Listed so the changeover is clear. |

## Before EWS: what that means for your oilhead

BMW's transponder immobilizer came to its motorcycles with the R 1200 GS in 2004. Everything in the oilhead family predates it. Open the rider's manual for an R 1150 GS, R 1150 R, R 1150 RT or R 1100 S and the key section is a few lines: you receive two master keys and one spare key, the key number is on a tag or label, and the locks share the key. There is no ring antenna, no EWS warning and nothing electronic in the key head.

For an owner this is good news. Any correctly cut key runs the bike, a spare is inexpensive to add, and a no-start is never a key recognition problem. If the engine cranks and will not fire, look elsewhere.

## Which locks the oilhead key fits

The manuals differ a little by model, and the differences are worth knowing before a visit.

- R 1150 GS and GS Adventure: ignition and steering lock, tank filler cap lock and seat lock, with the helmet holder at the seat lock
- R 1150 R: ignition and steering lock, fuel filler cap and a combined helmet and seat lock
- R 1150 RT and R 850 RT: ignition and steering lock, tank filler cap lock, dual seat lock, the storage compartment and the System cases
- R 1100 S: ignition and steering lock, fuel filler cap and seat lock, with cases for the same key available on request
- System cases on the GS and R: optional, and BMW says they can be ordered with locks for the bike key

## Age-related trouble on twenty-year-old locks

What goes wrong on these bikes is mechanical. Keys wear thin and round off, and a copy made from a worn key carries the wear forward. Locks that have gone twenty years without attention get sticky with old grease and dust, and case locks see the most weather.

Because the bikes have a key number, the cleanest fix for a tired key is one cut to the original number, not traced from the old key. If the ignition lock itself is loose, hard to turn or lets the key come out in the wrong position, it can be repaired or replaced and set up to match the rest of the locks.

## Lost key visit for an R 1100 or R 1150

No dealer order and no programming are needed. We check photo ID against the registration or title, then cut a key from the key number if you have the tag or label, or work the cut out from the locks on the bike if you do not. The new key is tried in the ignition, the tank cap, the seat or helmet lock and any cases you want on the same key.

If the bike has an aftermarket alarm or immobilizer added by an earlier owner, tell us. That equipment is separate from BMW's locks and can keep a bike from starting even with a perfect key.

## Where to find the key code

BMW's manuals for the R 1150 GS, R 1150 R and R 1150 RT say the key number is on the plastic tag that accompanies the keys; the R 1100 S manual describes a small self-adhesive label. Check the original document wallet. Without the number, the key is made from the bike's locks.

## 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 R 1100 and R 1150 oilhead boxers key FAQ

### Does a BMW R 1150 GS have a chip key?

No. BMW's 2002 US rider's manual for the R 1150 GS and Adventure describes two master keys, a spare key and a plastic key number tag, and has no immobilizer section. A cut key is all the bike needs.

### Will one key open the cases on my R 1150 RT?

It should on a bike with its original cases. BMW's manual says the RT key also fits the storage compartment and the System cases. Replacement or secondhand cases may have their own key until the locks are matched.

### I found a sticker with a number in my R 1100 S paperwork. Is that the key code?

Quite possibly. BMW supplied the R 1100 S with a small self-adhesive label showing the key number. Keep it safe and give us the number when you call.

### My oilhead key turns but feels sloppy. Key or lock?

Often both. A key cut fresh to the original number shows quickly whether the lock is the remaining problem. If it is, the lock can be serviced or replaced without changing the key for the tank cap and seat.
