Yamaha Zuma 50 and Zuma 125 Key Replacement

Quick answerYamaha Zuma scooters use a plain cut key, and the Zuma 50 and Zuma 125 owner's manuals list no immobilizer. On the Zuma 125 the keyhole sits behind a cover that is opened with the bow of the key, so a replacement needs the correct key head as well as the correct cut. On the 2005 Zuma 50 the one ignition switch also locks the steering and opens the seat.

The Zuma 125 keyhole cover

The Zuma 125 has a cover over its keyhole. Yamaha's manual describes how it works: insert the key bow into the keyhole cover receptacle and turn the key to the right to open the cover. To close it, push the keyhole cover lever inward. Whether a keyhole cover is fitted varies by model and year, so a photo of the ignition tells us what you have.

The bow is the head of the key, the part you hold. That is the catch with replacement keys for this scooter. A key cut on a blank with a plain head can turn the ignition once the cover is open, but it may not open the cover. If the cover is shut and the only key is lost, you need a key with the proper head. When you call, tell us whether the cover is open or closed. It changes the job.

One switch does almost everything on the Zuma 50

The 2005 Zuma 50 manual shows how much rides on a single lock. The main switch has ON, OFF and LOCK, and the steering locks with the bars turned all the way to the left. The same switch releases the seat: turn the key counterclockwise without pushing in, and the seat folds up. The helmet holder and the storage compartment are under that seat. The fuel cap is not keyed at all. It has a lever that moves between LOCK and OPEN.

So on that scooter a worn ignition means trouble with starting, steering and storage at the same time. It also means a replacement key only has to fit one lock.

Lost or broken Zuma keys

Scooter keys are small, and they can break when a stiff seat release is forced. If a piece is left in the switch, do not push another key in behind it. A broken key can usually be taken out and a new one cut from the pieces or from the lock.

With every key gone, we check your photo ID and registration or title and cut a key to the scooter. There is no chip to program on a plain-key Zuma.

Where to find the key code

The Zuma manuals include an identification numbers section in the consumer information chapter. Yamaha's key number is on the tag supplied with the keys.

Yamaha Zuma 50 and Zuma 125 key FAQ

Why will my copied key not open the Zuma 125 keyhole cover?

The cover is opened by the bow of the key fitting into a receptacle, according to the owner's manual. A copy with a plain head has the right cut but the wrong bow.

Do Yamaha Zuma keys have a chip?

No immobilizer appears in the 2005 Zuma 50 manual or the 2020 and 2021 Zuma 125 manual. They are plain cut keys.

How does the seat open on a Zuma 50?

On the 2005 model the manual says to put the key in the main switch and turn it counterclockwise without pushing in. The seat then folds up.

My key broke off in the Zuma ignition. What should I do?

Leave it alone and keep the broken half. The piece can usually be extracted and a new key cut without replacing the switch.
