> The Nighthawk 250 and Nighthawk 750 are plain-key motorcycles with no immobilizer. On the 250, Honda's manuals show one key working five separate locks, including a steering lock away from the ignition and a combined helmet holder and seat release. A lost key is cut to the bike, and worn locks are the main thing to watch on machines this age.

**Honda Nighthawk 250 and 750 key quick facts**

- Honda's Nighthawk 250 (CB250) manuals for 2004, 2005 and 2007 have no HISS or immobilizer section.
- The Nighthawk 250's steering lock is a separate cylinder at the right front, turned 180 degrees with the bars at full left.
- On the 250 the helmet holder lock at the left rear also releases the seat, through a seat lock lever.
- The 250's tool kit sits in a keyed compartment under the right side cover.
- The Nighthawk 750 is a plain-key Honda; its 1991 manual lists an ignition switch and a helmet holder and has no section on coded keys.

## Honda Nighthawk 250 and 750 key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| 2004-2007 | Nighthawk 250 (CB250) | mechanical cut key | no | One key for the ignition switch, separate steering lock, fuel fill cap, helmet holder and seat release, and tool kit compartment. |

## The Nighthawk 250: a small bike with a lot of locks

The CB250 Nighthawk changed very little over its long run as a training-school and commuter bike, and its locks are a snapshot of how Honda did things before everything moved to the ignition switch. The ignition only turns the electrics on and off. Everything else has its own little cylinder, all cut to the same key.

- Steering lock at the right front: turn the bars fully left, insert the key and turn it half a turn clockwise
- Fuel fill cap: key in the cap, turn clockwise
- Helmet holder at the left rear: key clockwise unlocks it; turn back to lock and remove the key
- Seat: with the key turned clockwise in the helmet holder lock, pull the seat lock lever down and slide the seat back; turn the key counterclockwise afterwards to lock the seat
- Tool kit compartment under the right side cover: key clockwise in the slot on the compartment cover

## The Nighthawk 750

The 750 was sold from 1991 to 2003 as a simple air-cooled four. That simplicity extends to the key. It is an ordinary cut key, and the bike has no electronics that care which key is in the switch.

What the 750 does have is age. An ignition switch that has been turned daily since the 1990s develops slop, and a key copied from a copy from a copy drifts further from the original each time. If a new key from a hardware store does not work as well as the old one, that drift is usually why.

## Used bikes, training bikes and missing keys

Nighthawk 250s often spend years in rider training fleets and then get sold on, sometimes with one tired key and no key number. On any bike that has had locks replaced during repairs, the ignition key may no longer fit the helmet holder or the tool compartment. Since the seat release on the 250 depends on the helmet holder lock, a mismatch there means you cannot get the seat off to reach what is under it.

If you have just bought one, try your key in every lock on the list above. It takes two minutes and tells you whether you have a complete, matching set.

## Replacing a lost Nighthawk key

We start with proof of ownership: photo ID and the registration or title in your name. On a recent purchase a signed-over title or bill of sale does the same job. The key is then made to the ignition where the bike is parked. On a 250 we go on to check the steering lock, fuel cap, helmet holder and tool compartment, and on either model a lock that no longer matches can be rekeyed. Where an ignition is too worn to hold a key reliably, we will show you and talk through repair or replacement before doing anything.

## Where to find the key code

Honda's Nighthawk 250 manuals ask you to write the key number in the Quick Reference section at the back and note that the selling dealer may have it on record. On older Hondas the number is sometimes stamped on the original key. If neither survives, the number is recovered from the lock.

## 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)

## Honda Nighthawk 250 and 750 key FAQ

### How do I get the seat off a Nighthawk 250?

Put the key in the helmet holder lock at the left rear, turn it clockwise, pull the seat lock lever down and slide the seat back. If that lock does not accept your key, the seat stays on until the lock is sorted out.

### Do Nighthawks have any kind of immobilizer?

No. These are plain-key bikes. A correctly cut key is all that is needed to start one.

### Why does my new copy work worse than my old key?

A copy reproduces the wear on the key it was made from. On a bike this old, a key cut to the original factory depths from the lock or the key number works better than a copy of a worn key.

### The steering lock on my Nighthawk 250 is a different key from the ignition. Is that normal?

It left the factory on one key. A different key means a lock was replaced at some point, and it can be rekeyed to match.
