Lock rekeying is one of the most practical and cost-effective security decisions a homeowner, renter, or business owner can make. The problem is that most people do not know it is an option until they are already in a situation where they wish they had done it sooner.

If you just moved into a new property, lost a key, ended a tenancy, or had any kind of access change, rekeying your locks is the fastest way to regain full control over who can enter your space. Janesville Locksmith Service provides professional lock rekeying for residential and commercial properties throughout Janesville, WI and Rock County.

What Lock Rekeying Actually Does

When a locksmith rekeyes your lock, they change the internal pin configuration inside the lock cylinder. That change makes every existing key for that lock useless. A new key is then cut to match the updated pin configuration.

The lock itself, the hardware, and the door all stay exactly as they are. Only the key that works changes. This is why rekeying costs significantly less than full lock replacement in most situations.

When You Should Rekey Your Locks

The most common reasons our customers in Janesville request rekeying include:

  • Moving into a new home or apartment
  • Losing a house key and not knowing where it ended up
  • A roommate or partner moving out
  • An employee leaving a business with a key that was not returned
  • A contractor or service provider who had temporary access
  • Purchasing a property and wanting to start with fresh key control
  • A previous security incident where key control was compromised

In each of these situations, rekeying delivers immediate, verifiable key control at a fraction of the cost of replacing the entire lock.

Rekeying vs. Replacing Your Locks

A common question we hear is whether to rekey or replace. Here is a straightforward way to think about it.

Rekey when:

  • Your existing lock hardware is in good working condition
  • You simply need to eliminate access for old keys
  • You want a cost-effective solution with the same security outcome

Replace when:

  • The lock is damaged, worn, or malfunctioning
  • You want to upgrade to higher-security hardware
  • You are installing a smart lock or keyless entry system

We assess your locks at no charge and give you a direct recommendation before any work begins.

Frequently Asked Questions

Should I rekey my locks after moving? Absolutely. Rekeying ensures previous keys no longer work and is one of the most cost-effective ways to improve security when taking over a new property.

Can all locks be rekeyed? Most standard pin tumbler locks can be rekeyed. Some older or specialty lock types may require replacement instead. We will assess your specific hardware and advise you accordingly.

How many locks can you rekey at once? We can rekey all exterior and interior locks in a single visit. Most residential rekeying jobs are completed within an hour depending on the number of locks.

Is rekeying as secure as replacing the lock? Yes, when the existing lock hardware is in good condition. Rekeying changes the key that operates the lock, which is the security outcome you are looking for.
