[Permanent Preservation Edition] Motorcycle and Moped Key Loss Manual! From Creation Methods to Cheap and Quick Solutions
What to do if you lose your motorcycle or moped key
Many of you may have experienced the panic of not being able to find your motorcycle or moped key when you're about to go out, desperately searching all the places you can think of, or realizing the key isn't where it usually is. This article explains how to deal with a lost key.
In addition, it also explains how to deal with a key that is broken and unusable, not just lost. Please use this article as a guide for troubleshooting motorcycle and moped key problems.
First, if you've lost your key, it's best to follow these steps:
- Check inside your bag and clothing pockets.
- Check if it's locked inside the helmet compartment (for motorcycles with a helmet compartment).
- Check for a spare key.
- Check roadside assistance and optional insurance.
- If you live with family, ask them.
1. Check inside your bag and clothing pockets
Unless someone else has taken it, your motorcycle or moped key should be somewhere within your area of activity. So, first, check if it's in your bag or clothing pockets.
If you lost it at home, retracing your actions from opening the front door upon returning home might help you find the key.
It's also a good idea to take a break and then search again.
Have you ever experienced finding something that you searched for endlessly but couldn't find, suddenly appearing later?
When you're in a hurry, you tend to search the same places repeatedly. So, if you have time, it's a good idea to take a break and then search again.
2. Check if it's locked inside the helmet compartment.
For motorcycles with helmet compartments, locking the key inside after putting it in is a common problem for two-wheelers.
According to JAF, which provides roadside assistance for two and four-wheelers, locked keys were the 4th most common reason for call-outs in 2020 (4,236 cases / 6.16% of total).

Check if the key is locked inside the helmet compartment. If you have a spare key, open the helmet compartment and check inside.
If you don't have a spare key, you'll need to request locksmith services from a roadside assistance provider like JAF or a locksmith.
JAF is Japan's largest roadside assistance provider with over 20 million members. Membership costs 6,000 yen (including enrollment and annual fees) (renewal is 4,000 yen/year).

Also, if you have optional insurance, roadside assistance may be included, so it's a good idea to check. We will also introduce nationwide mobile locksmiths in a later section, anticipating situations where locking assistance is needed, so please refer to it.
3. Check for a spare key.
If you've searched everywhere and still can't find your key, check for a spare key.
If you have a spare key at home and lost your key while out, you can retrieve the spare key from home to be able to ride your motorcycle or moped again.
If you are not enrolled in roadside assistance services like JAF, requesting them often costs more than 10,000 yen, so if the round trip cost is less than 10,000 yen, it is recommended to go back and get it yourself.
If you leave your motorcycle for a while, ensure it's locked to prevent theft or vandalism, cover it if possible, and move it to a less conspicuous location before leaving.
4. Check roadside assistance and optional insurance.
If you are subscribed to roadside assistance services like JAF, confirm that your membership is valid before making a request.
Also, if you have optional insurance, roadside assistance is often included, so you can use it by contacting your insurance company.
You can use it regardless of your optional insurance policy rating, and it doesn't affect your rating, so if you have optional insurance with roadside assistance, you should consider using it.
5. If you live with family, ask them.
If you lose your key at home and live with family, it's a good idea to ask them if they've seen the key.
Also, if you lose your key while out, asking a family member to pick you up or bring you a spare key is an option.
If the key is not found, file a loss report with the police.
If you can't find your key after searching extensively, file a loss report with the police.
By filing a loss report, if someone else finds your key and turns it in to the police, you will receive a notification.
To file a loss report, you simply need to provide your address and name, describe the key's shape and characteristics, and the approximate location where it was lost to the police officer. You can file a loss report not only at the nearest police station but also at a police box, so be sure to do so to increase the chances of finding your key.
How to deal with a lost key
Here, we explain how to deal with a lost key.
We'll cover common methods like requesting roadside assistance, as well as quicker solutions for when you're in a hurry and methods for minimizing costs. Please refer to this information.
1. Call JAF to request key unlocking.
If you are a JAF member, you can contact JAF to request key unlocking services.
Key unlocking is free for members, but non-members will be charged 13,100 yen (tax included) (as of January 2022).
If key unlocking is not possible, they will transport your vehicle to the nearest motorcycle shop or your home, with the first 15km free. Since JAF membership is for individuals, not the motorcycle itself, roadside assistance is available even if you're renting a motorcycle. Therefore, if you're not a member, you might consider joining.
It's important to note that if you have optional insurance, roadside assistance may also be included, so you need to check to avoid duplicate memberships.
Joining JAF is easy through their official website.

2. Request unlocking from your optional insurance's roadside assistance.
If you have optional insurance, free roadside assistance may be included.
Roadside assistance can be utilized by contacting your insurance company, so request them to unlock it.
3. [Quick Solution] Request key unlocking/key creation from a locksmith.
JAF and optional insurance roadside assistance services address requests in the order they are received, so you may have to wait a long time for your turn. If you don't have time to wait, hiring a locksmith often resolves the issue faster than waiting for roadside assistance, so consider this option if you're in a hurry.
While roadside assistance is free, requesting key unlocking or creation from a locksmith will incur costs exceeding 10,000 yen, so it becomes a matter of balancing time and budget.
4. [Cheaper Solution] Request key creation at a motorcycle shop.
If you want to keep costs down, you can ask a motorcycle shop to create a key, but this can take time.
When you request a key creation at a motorcycle shop, the shop orders the key from the manufacturer based on the key cylinder number, which requires about 1 to 2 weeks for delivery.
While it takes time, depending on the manufacturer and model, it costs around 2,000 to 5,000 yen, which is significantly cheaper than hiring a locksmith.
Losing an immobilizer or smart key can be expensive.
Smart keys with immobilizers are convenient as they allow engine starting even when kept in your pocket. However, if you lose one, the cost of creating a new one will be significantly higher compared to a plain metal key.
While a metal key can be made for around 8,000 to 10,000 yen, a smart key can cost anywhere from 15,000 to 30,000 yen (for imported cars), which is considerably more expensive.
Also, locksmiths may not be able to handle smart keys with immobilizers, in which case you will have no choice but to ask a motorcycle shop.
Even if they can handle it, the financial burden will be significant, so it's a good idea to contact several locksmiths for quotes and compare them to reduce the cost.
Cost and price range for lost keys
How much does it cost if you lose your motorcycle or moped key?
If you lose your key, the appropriate course of action varies depending on the situation, such as "the key itself is missing" or "it's locked inside the helmet compartment." We'll introduce the average costs for different key-related issues, so please refer to this when requesting services from a professional.
Average price for requesting key unlocking.
If you lock your key inside the helmet compartment and request a locksmith to unlock it, the cost generally ranges from 8,000 to 150,000 yen, depending on the vehicle model and the location of the lock.
If the ignition key and the helmet compartment key are the same, the keyhole is complex, which can sometimes cost around 20,000 yen.
The longer the work takes, the higher the cost. So, if it's easy to open, the cost is lower, and if it takes time or requires additional work, the cost tends to be higher.
Average cost for losing a helmet compartment key.
If the ignition key and the helmet compartment key are different, and you lose the helmet compartment key, the average cost for unlocking is around 8,000 to 10,000 yen.
Even if you don't have a spare key, it's possible to create a duplicate, and the average cost for creating a key for the helmet compartment lock is around 10,000 yen.
Average price for creating duplicate/spare keys.
The cost of creating duplicate or spare keys varies depending on the motorcycle or moped model and the difficulty of creation, but the average cost ranges from 10,000 to 50,000 yen.
It is possible to create duplicate/spare keys even if you don't have the original key. However, if it's a shutter-equipped cylinder that combines the shutter and ignition key, some locksmiths may not be able to create it, so confirm if it's possible before requesting.
Average price for key replacement.
The cost of key replacement also varies depending on the vehicle model, with imported vehicles tending to be more expensive than domestic ones.
The cost of replacing the cylinder where the key is inserted, plus labor costs, typically ranges from 15,000 yen to 30,000 yen.
For complex structures like those with shutters, parts tend to be more expensive, so the cost will also be higher.
What do I need to have a locksmith make a lost key?
When having a locksmith make a lost key, you will need your driver's license, compulsory liability insurance certificate, and payment. Some locksmiths may also require a local government registration certificate or vehicle inspection certificate (for motorcycles that require inspection).
It's important to have duplicate/spare keys just in case.

It's recommended to have duplicate/spare keys in case you lose your original key.
Not only might you be unable to find it where you thought you left it, but there are also cases where it might accidentally fall into a ditch or waterway outside and become unretrievable.
It's crucial to have a duplicate or spare key as a precaution.
Can a motorcycle with a lost key be sold? Can it be bought back?
Even if a motorcycle has a lost key, it can still be sold if a new key can be made.
However, the purchase price will likely be reduced by the cost of creating a new key after the buyback.
