All key duplication is backed by replacement or money back guarantee and liability is limited to the retail price of the key. Exceptions occur when keys to be copied are too badly worn to guarantee a perfect working copy. The company reserves the right to bring this to the attention of customers and offer the customers the option to proceed entirely at the customers risk which will negate any guarantees. This also applies when requests to duplicate keys that have been bent or broken and the company reserves the right to mark all such keys so as to identify them as supplied after advice. Keys supplied to code numbers are not replaced or refunded unless there has been a cutting error on the part of the company. Certain lock and key systems are protected by law and replacement or extra keys will not be duplicated without the correct authorization procedure. The company is obliged to operate these procedures to comply with law and in the best public interests.
