Key Identification and Setup
Before using your replacement key, it is crucial to verify that it matches your lock's code. The correct key is determined by the lock code, which is typically stamped on your original key or directly on the face of the lock cylinder.
Identifying Your Lock Code:
- Check Original Key: If you still possess your original key, locate the stamped code on its head. This code will be in the format "E00X" (e.g., E003).
- Inspect Lock Face: If the original key is lost, examine the face of the lock cylinder on your office furniture. The code should be visible there.
Ensure the code on your replacement key (E003) matches the code found on your lock or original key. Mismatched codes will prevent the key from operating the lock.
Operating the Key
The Ojmar E003 replacement key functions identically to an original key for compatible Ojmar cabinet locks.
Basic Operation:
- Insert Key: Gently insert the E003 key into the keyway of the Ojmar lock cylinder. Do not force the key.
- Turn Key: Once fully inserted, turn the key clockwise to lock or counter-clockwise to unlock, depending on the lock mechanism's design. The key should turn smoothly.
- Remove Key: After operating the lock, return the key to its original insertion position (usually vertical) before removing it.
If the key does not insert or turn smoothly, do not force it. Refer to the Troubleshooting section.
Maintenance
The Ojmar E003 key requires minimal maintenance to ensure its longevity and proper function.
- Keep Clean: Periodically wipe the key with a dry, soft cloth to remove dust or debris.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents on the key, as these can damage the metal finish.
- Proper Storage: Store the key in a dry place, away from extreme temperatures or corrosive environments.
- Lubrication (for lock): If the lock mechanism becomes stiff, a small amount of graphite powder or a specialized lock lubricant can be applied directly into the lock cylinder, not on the key itself. Consult a locksmith if unsure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Key does not insert fully. | Incorrect key code; debris in lock; bent key. | Verify key code matches lock. Check for and remove debris from keyway. Inspect key for damage; replace if bent. |
| Key inserts but does not turn. | Incorrect key code; internal lock mechanism issue; key not fully inserted. | Confirm key code. Ensure key is fully inserted. If lock is stiff, apply lock lubricant. If problem persists, the lock may require professional service. |
| Key is difficult to remove. | Key not in neutral position; internal lock mechanism issue. | Ensure key is returned to the vertical (neutral) position before attempting removal. Apply lock lubricant if stiffness is present. |
