How to Change Combination Locks

If an old lock simply doesn't work or look the way it used to, it's probably time to change the lock. Changing a combination lock takes moments, and most older locks can be stored for later use in case of an emergency. Be certain to save the combination code after putting on the new lock.

Things You'll Need

• Combination or key for old lock Bolt cutter (in case of lost combination) Paper Pen New lock

Instructions

1. Open the old lock with the combination or key. If the lock is old with no remembered combination or key entry, use a universal key (available through a locksmith only) or bolt cutter to break the lock off.

2. If the lock is salvageable after removal, close it shut. Write the combination on a small slip of paper and securely tape it to the back of the lock for safekeeping.

3. Open the package for the new lock. There will be a small card or paper with the combination. Practice opening and closing the lock several times to make certain that the mechanism works. If there's a key, pocket it or place it someplace safe.

4. Apply the new lock to the area that requires securing. Place the combination in an easy-to-remember spot for later use.
