What Exactly Is Rekeying A Lock?

Lock rekeying is the process of changing the lock code. The lock is taken apart, and the locking pins and springs are replaced. Then, new keys are cut to match the new locking pins. At this point, the old keys will not operate the lock.

Why Should You Rekey A Lock?

There are many reasons for rekeying a lock, but they should all revolve around security and key control. Let’s say that a bank has five keys that open the bank doors, and when they do an audit, they discover that they cannot account for one key. They have two choices: replace all the locks that the lost key opened, or rekey them. If the door hardware is in good condition, then the choice should be to rekey. A locksmith like phoenixlocksmithpros.net can do this job at the bank and cut new keys to match the rekeyed locks.

Key control is the process of knowing where all your keys are and who has them. If you can’t account for even one, rekeying should be your first action. Remember, without Control you do not have a secure facility. Most quality locks can be rekeyed, and if the lock happens to be high security, you will get a new registered code with registered keys.

For example, if you have multiple doors that work with a different key (keyed different) and you want these doors to all open with the same key (keyed alike). All of these locks can be taken apart and rekeyed to open with the same key. To take this a little further, you can create a master system. This is when all the doors open with different keys, but you have one (master) that will open all the doors.

To rekey a lock, the cylinder must be made to be removed from the padlock. Once removed, the combination pins are changed to a new configuration, and keys are cut to match. This process can be done many times. Not all padlocks are reliable, though. It depends on the manufacturer, the manufacturing process, and the cost. Most padlocks sold at big box stores are not reliable.

If you lose your keys and want to ensure your stuff is still secure, you either have to purchase new padlocks or rekey them. The rekey process is much cheaper. For years, high security padlocks were manufactured to be rekeyable. With these locks the rekey process is a little different. These types of locks use restricted lock and key codes. This usually means that only you will have those lock codes and the keys to open those locks.

For Businesses, These Types Of Locks Offer Many Benefits:

There is another type of lock cylinder that goes into padlocks. These are called removable core, SFIC, or changeable. With these, the complete lock cylinder is removed from the padlock and replaced with another one. The core can then be rekeyed and ready for use in another padlock. The benefit to these locks is that anyone can change the padlock core. This helps you immediately regain control of your keys. Removable core padlocks are usually available only at service centers or locksmith stores and cost more than standard padlocks.

So how can you tell if a lock is rekeyable? For the average person, it could be challenging. If you go to big box stores, the padlocks are usually carded, sealed in plastic, and hung on a hook. Unless it is stated on the packaging, it would be not easy to know. I don’t think that store personnel would be any help. If you want this type of padlock, go to a professional Service Center.
