What is Rekeying a lock?
While “changing a lock” is quite self explanatory, simply referring to changing an old lock with a new one, rekeying requires a bit of explanation to be understood. Rekeying a lock means to change the working key of the lock to a different key, without replacing the lock itself. In simpler words – you keep the same lock but the old key will no longer operate it. This is done by taking the lock apart and replacing some of the parts inside (called “tumblers” or “key pins”).
In order to rekey a lock, the locksmith has to have its current matching key. Without the matching key, the only way to rekey the lock will be to pick it open, and although it’s usually not a problem for a skilled locksmith, it will often incur additional charges which can make it more expensive than replacing the lock altogether.
Rekeying a lock does not hurt the security of the lock, nor does it make it more secure. One of the factors that makes a lock secure is how many pins are inside of it. As long as the locksmith swaps the old 5 pins with 5 new ones, the lock will remain just as secure as it was before. If you’re looking to get better security of your locks, changing them to new, higher security ones will be the way to go.
Due to the extremely low price of the key pins in the locks, rekeying is almost always much cheaper than getting your locks changed. When rekeying your locks, you are only being charged for the labor, whereas when you get your locks changed, you’re paying both for labor and parts.
One important thing to keep in mind is that all the locks come with a built in option to be rekeyed, so you don’t have to wonder whether your locks are rekeyable or not. However, the way to rekey different locks is not always the same and often requires different tools.
Rekeying is not only used when you want to retire an old key, but also to match more than one lock for the same key. For example, if your home has several locks and each lock has a different key, which can be inconvenient, you may want to rekey the locks to all match the same key. Keep in mind that in order to match 2 locks or more for one key, the locks has to be of the same brand or to share the same types of keyholes. If your key fits into one lock but won’t go into the other, it means their keyholes (or “keyways”) are different and they cannot be matched.
When should you change your locks?
1. You want your locks to be in a different color or design. For example, if you moved into a new place and your locks are old and rusted, you may want to get a new, nicer looking locks. 2. When you want to upgrade your security and change your locks to high security locks or electronic locks. 3. If you have locks of different brands on your house and you want them all to work on the same key, you will need to change some locks so that all your locks will be of the same brand (or have the same type of keyway), only then you can re-key them all to one key.
In cases where you have one or more locks installed but don’t have the key for them at all, you will need to compare the price of a new lock versus rekeying them without a key (which requires extra labor) and make an informed decision as to what is more cost effective. Only in cases where picking the lock and rekeying it is more expensive than the price of a new lock, you should change it.
Note that when getting your locks changed, the locksmith should be able to supply you with at least a few locks with a matching key. At Crouse Lumber we will match your locks for free upon purchase.
