There are many reasons why you might want to either rekey locks or change locks on doors. Perhaps you’ve moved into a new home and don’t know who else has keys. Maybe you’ve lost your keys. Or you think that too many people have copies of your keys.
It doesn’t matter – you want things changed. You’ll need to choose between using rekey services or changing locks completely. Which option is best for you? In this post, we’ll look at both options so you can make an informed decision.

Choose to Rekey Door Locks
Most people believe that losing keys means having to get new locks. You don’t always need new locks. If you choose to rekey the old lock instead, you could save yourself time and money. And, contrary to popular belief, this does still prevent old keys from working.
The locksmith removes the lock and switches out screws and pins. You now have a lock that works with your new key. It’s the same locking mechanism, but “reprogrammed” for a new key.
There are videos online that show you how to do this. We don’t advise you to do it yourself unless it’s an extremely simple lock. As a layperson, you’ll have to buy a new lock and key anyway. If that’s the case, you may as well just change the locks.
Think of it this way – DIY won’t do you any good if we have to come and fix your repairs.
Pros
- It’s cost-effective. Instead of replacing the entire unit, you replace some of the screws and pins.
- You get heightened security. Old keys won’t open these locks, so it’s almost the same as swapping out the whole unit.
- The work goes faster.
- It’s more environmentally friendly. Because only a small part of the lock is changed, there’s less waste produced overall.
Cons
- The lock must be in good working order for rekeying to be effective. If the locking mechanism shows significant signs of wear or damage, you have to change the lock.
- Not all locksmiths are willing to offer to rekey.
- Very few people even know about rekeying.
When is Rekeying a Good Idea?
- If you’re moving into a new property or don’t know who might have access to it, rekeying is a simple fix.
- You’ve lost your keys.
- Someone stole your keys.
- You think that too many people have copies.
- You’re looking for a budget-friendly alternative.
- You want extra security.
Lock Replacements
You’d be surprised at this, but not many people realize rekeying is an option. There are times, though, when changing the whole mechanism is a better idea.
To change the lock, a technician can remove the mechanism and replace it with a new one. If you’re handy, you could do this yourself. Just be sure to note how things were set up with the old lock. If you’re choosing the same model, it’s simple enough.
If you want to upgrade your security, we recommend calling in a locksmith. While this will cost some money, you’ll get the best advice. You’ll also be able to get better locks at favorable prices thanks to the contractor’s bulk-buying discount.
The pro will also check the strike plate and doorknob. If these need to be changed, the locksmith will advise you.
Pros
- You’re getting a whole new mechanism. There’s no way that anyone could have keys.
- You can benefit from updated technology or better quality.
- It’s easy enough to change over to a keyless entry system.
Cons
- It costs more.
- It takes longer.
When are Lock Replacements a Good Idea?
- When your locks are old or broken. Say, for example, a lock keeps sticking. If a bit of WD-40 doesn’t loosen it up, you probably need to replace it.
- You’ve had a burglary.
- You want to upgrade your security with better quality locks.
- You want to incorporate new technology.
- You’d like to have the same key for multiple locks.
- You’re interested in changing up the aesthetic.
- You’re injured or disabled and need a more straightforward solution.
Final Notes
Rekeying is a perfectly good solution in most cases. We usually recommend this solution if you have good locks in great shape. That said, if you need a security upgrade, new locks could be a better solution.
