FAQs

What makes the Alarm-D Pro 'maximum-security'?

It comfortably surpasses the Sold Secure Pedal Cycle GOLD standard, featuring an upgraded, thick lock body and a 14mm special hardened steel shackle designed to resist cutting and breaking.

How does the 120db alarm work?

The alarm is weatherproof and activated by movement and shock. If someone tries to tamper with or move your locked bike, the loud siren will sound to deter them and attract attention.

Can I replace the keys if I lose them?

Yes, Oxford offers a key replacement service. When you purchase the lock, make a note of the unique number attached to your keys and keep it in a safe place.

Does the alarm have a motion sensor?

Yes, the alarm is activated by movement and shock, meaning any significant disturbance to the locked bike will trigger the siren.

What type of battery does the alarm use and how long does it last?

The alarm uses a replaceable Lithium CR2 battery. Battery life varies depending on usage and environmental conditions, but it is designed for long-term performance.

How do I prevent the lock from damaging my bike's paintwork?

The lock is coated in vinyl to protect your bike's paintwork. Ensure the vinyl coating is intact and avoid sliding the lock aggressively against the frame.

Is the alarm waterproof?

The alarm is described as weatherproof, meaning it is designed to withstand rain and outdoor elements, but it should not be submerged in water.

Troubleshooting

Alarm not sounding

Ensure the battery is correctly installed and has sufficient charge. Check that the lock is fully engaged to arm the alarm. Clean the sensor area if it appears obstructed.

Lock cylinder is stiff or difficult to open/close

Lubricate the lock cylinder with a graphite-based lubricant. Avoid using oil-based lubricants, which can attract dirt. Ensure no debris is present in the keyhole.

Carry bracket is loose

Re-tighten the screws or securing mechanism of the carry bracket. Ensure it is properly aligned with your bike frame before tightening.

False alarm activations

Ensure the lock is not being bumped or moved unnecessarily when armed. Check for environmental factors like strong winds or vibrations that might be triggering the sensor.

  • Battery: The lock uses a replaceable Lithium CR2 battery. When the alarm's performance diminishes, replace the battery following the manufacturer's guidelines. Keep the battery compartment clean and dry.
  • Key Management: Store your key number safely. This number is essential for the key replacement service.
