1. Introduction
This manual provides essential instructions for the EasyKeys B12148 replacement key. This key is specifically designed for Yamaha golf carts and other compatible Yamaha products that utilize the B11111 - B19999 key series, with the specific code B12148.
It is crucial to verify that your vehicle's lock code matches B12148 to ensure proper functionality. This key is compatible with various Yamaha models, including golf carts, motorcycles, ATVs, side-by-sides, snowmobiles, and other power products that use this specific key code.
2. Key Identification
Before using your new replacement key, it is vital to confirm that the lock code on your vehicle or original key matches the B12148 code. Incorrect key codes will prevent the key from functioning.

Figure 2.1: Locating Your Lock Code. This diagram illustrates common locations where you can find your lock code: directly on the key, on the face of the lock cylinder, on a label inside or behind the lock mechanism, or on a cabinet/door label associated with the lock.
Important Notes:
- Manufacturer Specificity: Lock codes are often manufacturer-specific. Always order by the manufacturer and ensure the lock code matches.
- Key Cut Variations: Even if codes appear similar, key cuts can vary significantly between different brands and models. Confirm both the manufacturer (Yamaha) and the exact code (B12148).

Figure 2.2: Example Replacement Key. This image shows a typical EasyKeys replacement key. Note that the code stamped on the key (e.g., B11111 in this example) should match your required code (B12148 for this product).
3. Setup and Usage
- Verify Compatibility: Double-check that your vehicle requires a B12148 key for Yamaha products.
- Insert Key: With the ignition or lock mechanism in the OFF or UNLOCKED position, gently insert the B12148 key into the keyway. Ensure it slides in smoothly and completely. Do not force the key.
- Operate Lock: Turn the key clockwise or counter-clockwise as required to engage the ignition or unlock the mechanism. The key should turn without excessive force.
- Remove Key: Once the desired action is complete, return the key to the neutral position (if applicable) and remove it.
4. Maintenance
Proper care will extend the life of your replacement key and the lock it operates.
- Keep Clean: Periodically wipe the key with a dry cloth to remove dirt, dust, or grime.
- Avoid Damage: Do not use the key for purposes other than its intended function (e.g., as a pry tool). Avoid bending or scratching the key blade.
- Lubrication: If the lock mechanism becomes stiff, apply a small amount of graphite-based lubricant directly into the lock cylinder, not onto the key. Avoid oil-based lubricants as they can attract dirt.
- Storage: Store the key in a secure location to prevent loss or damage.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
