Frequently Asked Questions

How loud is the alarm?

120dB — loud enough to alert you and deter thieves within a significant distance.

How long does the battery last?

Approximately one year of normal use. The CR2 battery is replaceable so you can swap in a new one without buying a new lock.

Yes — the lock has ARM/DISARM modes, so you can disable the alarm when towing or transporting your bike.

What does the ATPO cover provide?

Optional anti-theft protection up to $500 USD (€400 or £300 depending on region) if your bike is stolen while the Kryptolok is properly engaged.

Will this fit my motorcycle's disc brake rotor?

The 6mm locking pin fits standard disc brake rotors on V-twin bikes. If your rotor thickness is non-standard, verify compatibility before ordering.
