How to Unlock a Master Padlock #3 Without a Key

Padlocks help protect your valuable property.

Master Lock imports padlocks, combination locks and other security products for industrial and commercial use. The company's No. 3 padlock is a commercial grade keyed lock encased by a hard laminated shell. Master Lock's No. 3 padlock is intended to secure tool cribs, construction equipment, vending machines and storefront or business gates. Because of this lock's resistance to cutting and picking, a replacement key should be obtained if you wish to open it.

Things You'll Need

• Key number

Instructions

1. Contact Master Lock and request a set of replacement keys. This step requires that you know the identification number printed on your old set of keys. See the "Resources" section below for Master Lock's contact information.

2. Bring your key number to a hardware store or professional locksmith to have it duplicated.

3. Take your No. 3 padlock to a hardware store or professional locksmith if you have lost or do not remember your key number. The technician will make an impression of your lock and create a new set of keys which will unlock it.

Tips & Warnings

• Always store your key number in the Master Lock Vault, a free service provided by the company. See the "Resources" section below.

• Phone the hardware store or locksmithing service in advance to check that they offer a lock impression service.

• Do not attempt to unlock a No.3 padlock--or any other lock, for that matter--that does not belong to you. Such action may be met with legal consequences.

• Do not attempt to cut or pick a No.3 padlock, even if you own the lock and the property to which it is secured, as this may be mistaken for theft.
