Common situations where homeowners get their locks rekeyed with LockSmart

 

• Just moved into a new home or rental property (you have no idea how many copies of the key are out there) and want to ensure they are the only ones with the keys. 
• Their keys have simply gone missing or have been stolen.
• After a relationship breakdown, flatmate departure, or family dispute we are commonly asked to re-key locks. 
• After a break-in or attempted break-in, even if the lock itself wasn't the target.
• Tradespeople, cleaners or contractors had access and their not sure who might have copied a key.
• They want to retire old spare keys in circulation without changing locks entirely

 

What Is Lock Rekeying?

Rekeying changes the internal pins inside your existing lock cylinder so your old key no longer works and a new key operates it instead. The lock body stays in place. Only the mechanism inside changes. It's just as secure as fitting a brand new lock, but can be considerably more cost-effective for Auckland homeowners.

If your locks are in good condition, rekeying is all you need to cut off access from anyone who has a copy.

Rekeying vs. Replacing Your Locks

If your locks are in good working order, often rekeying your locks is usually the right call. It costs less than full lock replacement and delivers a similar result: anyone with an old key simply can't use it anymore to gain access.

Lock replacement can sometimes make more sense in situations when:

• Your lock is damaged, worn, or no longer functioning reliably. Replacing a lock in bad condition is always recommended. 
• You want to upgrade to a higher security grade to increase the level of security at your home. 
• You're fitting a new door or replacing old hardware throughout the home due to renovations, upgrades and the likes.
