We are sorry to hear that the keys to your cable lock have been lost.For security, safety, and legal reasons, Regal Products does not stock or provide replacement keys, master keys, duplicate keys, or key codes. We also cannot provide instructions for bypassing or defeating an installed lock.Please do not load, fire, cycle, or force the action of the firearm while the cable lock is installed. Keep the muzzle pointed in a safe direction, keep your finger outside the trigger guard, and keep ammunition secured separately.The safest way to remove the lock while minimizing the possibility of firearm damage is to contact a qualified gunsmith or a locksmith who specifically works with firearm locking devices. Call before transporting the firearm and explain whether you can positively confirm that it is unloaded. When unloaded status cannot be confirmed, do not manipulate or transport it without first obtaining professional safe-handling instructions.If you’d like to replace your lock, we offer a wide variety of options on our FSDC by Regal Amazon page.
