Some locks come with an anti-theft guarantee, which means the company will pay out up to a stated amount if your bike is stolen because the lock was broken or opened by force – although they are often subject to many conditions and restrictions, such as being locked up correctly or the policy not being valid if torches or power tools are used. Similarly, some companies have 'key safe' schemes that make it easier to order replacement keys, or combination lock registration services in case you forget your code.
