> The Grom and Monkey use plain cut keys with no immobilizer, according to Honda's US owner's manuals. A lost key is cut to the bike on site and needs no programming. The one thing to know is that the Grom was supplied with a folding retractable key as well as a plain one, and a worn folding mechanism does not mean the bike needs anything more than a new cut key.

**Honda Grom and Monkey key quick facts**

- The 2018 and 2020 US Grom manuals and the 2020 US Monkey manual have no HISS or immobilizer section.
- The 2018 and 2020 Grom manuals describe both an ignition key and a retractable ignition key that folds out of a key case at the press of a release button.
- The Grom comes with a key number plate; the Monkey with two keys and a bar-coded key tag.
- On the Grom, one key works the ignition and steering lock, the fuel fill cap and the seat lock, and the helmet holder is under the seat.
- On the Monkey, the key also releases the left side cover and a locking helmet holder with its own lock cover.

## Honda Grom and Monkey key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| 2018 and 2020 | Grom, Grom ABS | mechanical cut key, supplied as one plain key and one retractable key | no | Key number plate supplied. Steering lock is in the ignition switch. |

## Small bikes, simple keys

Honda's 125 cc minis are built to be simple, and the keys are no exception. Honda's US manuals for the 2018 and 2020 Grom and the 2020 Monkey do not mention an immobilizer, a coded key or a security indicator. A new key only has to be cut to match the locks.

If yours is a different year, the Keys page of your owner's manual will confirm it in a few lines, and we check from your VIN when you call.

## The Grom's retractable key

The Grom manual lists two keys: a normal ignition key and a retractable ignition key. The retractable one lives in a plastic key case and swings out when you press the release button; to put it away you hold the button and push the blade back in until it clicks. Honda's only instructions are to avoid touching the blade while it moves and to make sure it is fully extended before use.

A folding key has more to go wrong than a solid one. A blade that is not fully extended, or a hinge that has loosened, puts sideways load on the key in the ignition. If your retractable key has gone floppy or the button no longer holds, use the plain key and have a solid spare cut. The blade pattern is the same on both, so either one can be copied.

## Which locks share the key

- Grom ignition switch with steering lock: push the key down and turn to the lock position. The key comes out in OFF or lock.
- Grom fuel fill cap, under a lock cover; the key stays captive until the cap is locked
- Grom seat lock. The helmet holder and document bag are under the seat, and the manual warns you not to lock your key under it.
- Monkey ignition switch with steering lock, and fuel fill cap under a lock cover
- Monkey helmet holder: open its lock cover, insert the key, hang the helmet on the pin and push to lock
- Monkey left side cover: the key turns clockwise in the cover's lock to release it

## All keys lost, and a word on theft

We confirm ownership with photo ID and the registration or title, cut a key to the bike's locks where it is parked, and test it in every lock. There is no programming. Honda's manual says that without the key number plate a dealer will probably have to remove the ignition switch assembly to find the number, so dig out the plate or key tag if you have it.

Because these bikes are light enough to be lifted by two people, the steering lock and a plain key are not much protection on their own. If your key was stolen and not just lost, tell us. Rekeying the locks so the old key no longer works is worth considering, along with a chain or disc lock.

## Where to find the key code

Grom: on the key number plate supplied with the keys; the manual asks you to record it in the manual and store the plate safely. Monkey: on the key tag, next to the bar code. If it is lost, the number can be recovered 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)

## Honda Grom and Monkey key FAQ

### Does the Honda Grom have a chip key?

No immobilizer appears in the 2018 or 2020 US Grom owner's manuals. Both the plain key and the retractable key are simple cut keys.

### My Grom's folding key is broken. Do I need the dealer?

No. The folding case is just a holder for an ordinary cut blade, so a solid replacement key can be cut on site from the other key or to the lock.

### Does the Monkey key open the side cover?

Yes. Honda's 2020 manual shows the ignition key turning clockwise in the left side cover lock to remove the cover.

### I locked my key under the Grom seat. What now?

It is a known hazard; the manual warns about it because the seat latches when pushed down. Call us and we will get the seat open and your key back.
