Can You Rekey a Rental Without Landlord Permission?

Can You Rekey a Rental Without Landlord Permission?

Short answer: in South Carolina, generally no, not without your landlord’s knowledge, though the details depend on your specific lease and the reason you want to rekey.

This comes up more than people expect, usually after a breakup, a roommate situation gone wrong, or just wanting peace of mind that a previous tenant’s keys no longer work.

The General Rule in South Carolina

South Carolina’s landlord-tenant law doesn’t give tenants an automatic right to rekey locks without the landlord’s involvement. Most leases require the landlord’s consent before changing locks, and many leases require the tenant to provide the landlord a copy of any new key. Altering locks without permission can be treated as a lease violation, separate from any locksmith issue.

Check your lease first. Some leases explicitly address this, either permitting tenant-requested rekeying with notice, or prohibiting it outright. The lease language controls here more than general assumptions.

When Landlords Are Expected to Rekey

Many landlords rekey between tenants as standard turnover practice, even without a specific law requiring it, simply because a previous tenant’s keys being active is a liability for everyone. If you’re moving into a new rental and haven’t been told the locks were rekeyed, it’s reasonable to ask directly before move-in.

What to Do If You Have a Safety Concern

If your concern is a genuine safety issue, like an ex-partner who may still have a key, that’s worth raising with your landlord directly and in writing. Most landlords will act quickly on a safety-based request, and having it in writing protects you if the situation needs to be escalated later.

What a Locksmith Can and Can’t Do Here

We can rekey any lock you have legal access to and authorization for. What we can’t do is rekey a rental unit without some form of landlord authorization, since we have no way to verify tenant vs. landlord rights over the property from a phone call alone. If you call us about a rental, expect us to ask a few questions about your lease and landlord communication before booking the job.

A Middle-Ground Option

Some tenants add a secondary lock, like a keyed deadbolt in addition to the existing lock, rather than rekeying the primary one. This can address a safety concern without altering the landlord’s existing lock, though this should still be discussed with your landlord first, since some leases restrict adding hardware too.

Have a Landlord-Approved Rekey to Schedule?

We handle rental rekeying across Summerville SC once authorization is confirmed.
